Free VPN Selection Tips

1. Stable connection

Even if there are not many nodes provided, the connection must be stable, otherwise no one can tolerate frequent disconnections.

2. Easy to use, convenient and fast

For novices and technical novices who are new to circumventing the firewall, the cumbersome operations and settings will simply discourage them.

3. The connection time is long after watching an ad

Watching an ad once an hour is barely acceptable, after all, you shouldn’t go too far in getting the freebies. But if you watch an ad once but the connection time is short, it’s a bit annoying.

4. The VPN manufacturer is not from mainland China

China has a strict Internet censorship system, and the government has the right to require service providers to hand over all user data. Security is not guaranteed.

5. Strict Zero-Log Policy

A strict zero-logging policy means that the service provider will not collect users' personal privacy and Internet data, and will not be able to sell private data.

What should I do if VPN cannot connect?

Using a VPN can effectively encrypt network connections, protect personal privacy and data security, bypass geographical restrictions, and access blocked websites. Sometimes we may encounter problems with VPN not being able to connect. This article will introduce some solutions.

The first possible reason is a VPN server failure. When we connect to a VPN, if there is a problem with the server, it may cause a connection failure. At this time, we can try to connect to other servers or contact the VPN provider for help. Free VPNs sometimes limit the quality of service for users, so it is recommended to choose a well-known and regular VPN service provider.

The second possible reason is a network problem. If you encounter connection problems when using a VPN, first check whether the local network connection is normal. You can try to reconnect to WiFi or use other network connection methods. After eliminating the network problem, try to connect to the VPN again.

The third possible reason is a VPN client configuration problem. Sometimes, when we use the VPN client, we may misconfigure it or miss some key parameters, resulting in a connection failure. At this time, we can check whether the configuration is correct and make sure our account information is correct. If the configuration is correct and you still cannot connect, you can try to reinstall the VPN client or upgrade to the latest version.

The fourth possible reason is firewall restrictions. Some regions may have firewall restrictions that block some VPN connections. In this case, we can try to use a free VPN service, because free VPNs may be more flexible and can bypass firewall restrictions in some regions. However, it should also be noted that free VPNs may have some security risks, so it is important to choose a regular and reliable free VPN service provider.

In addition to the common reasons mentioned above, there are other problems that may cause VPN to fail to connect. For example, there may be software conflicts in our devices, causing VPN to fail to work; or our device system needs to be updated, VPN is not compatible, etc. For these problems, we can try to close other conflicting software or processes, or update the device system and VPN client.

In summary, when VPN cannot connect, we should first determine the cause of the problem and then take appropriate measures to solve it. You can try to connect to other servers, check whether the network connection is normal, troubleshoot VPN client configuration problems, or seek help from the VPN provider. For situations where VPN connection is stuck in some areas, you can try to use a free VPN service. Whether using a free VPN or a paid VPN, you should choose a well-known and regular service provider to ensure data security and privacy protection.

I hope that through the introduction of this article, readers can better understand VPN connection problems and successfully solve the problems they encounter.

What Streaming Media Can a VPN Unblock?

Different countries and regions restrict access to certain streaming platforms, which means you may not be able to watch your favorite TV shows, movies, or sporting events.

Fortunately, VPN, as a technology that can hide the user's real IP address and change the virtual location, provides us with a way to bypass geographical restrictions. Whether it is a commercial VPN service or some free VPN providers, they can help us unblock many domestic and foreign streaming platforms.

Let’s take a look at which overseas streaming platforms VPNs can unblock. Netflix is ​​one of the world’s largest video-on-demand platforms, providing users with a large number of popular movies, TV series, and documentaries. Due to geographical restrictions, Netflix content may vary in different countries or regions. By using a VPN, you can choose to connect to the desired virtual location and easily unblock Netflix content in other countries.

Similarly, platforms such as Hulu, Amazon Prime Video, and Disney+ are also restricted to different regions to varying degrees. Using a VPN, you can bypass these restrictions and get more video resources.

In addition to overseas streaming platforms, VPNs can also unblock some domestic streaming platforms. For example, users in mainland China cannot directly access foreign social media platforms such as Google, YouTube, and Facebook. Some VPN service providers provide Chinese servers. By connecting to these servers, users can break through network blockades and enjoy the global Internet.

Users in mainland China often encounter problems with being unable to access certain overseas streaming platforms. For example, many overseas TV series, movies and other resources cannot be watched in China, which has caused trouble for many fans of American and Korean dramas. By connecting to foreign servers, VPNs can help users bypass geographical restrictions and enjoy a variety of overseas streaming content.

Next, let's learn about some free VPNs. Although there are many commercial VPN services on the market, free VPNs are also an option. Although some free VPN providers limit some features, such as the number of users, connection speed, etc., they can still help us unblock streaming platforms. Well-known free VPN providers include Hotspot Shield VPN, TunnelBear VPN, Windscribe, etc.

It’s important to note that not all free VPNs can reliably unblock streaming platforms. Some free VPN providers may restrict streaming to encourage users to purchase their paid versions. Therefore, if you want to use a free VPN to unblock streaming platforms, it’s best to look for relevant reviews and comments beforehand to assess its reliability.

In summary, VPN, as a tool to bypass geographic restrictions and unlock streaming platforms, has brought us great convenience. Whether it is a domestic or foreign streaming platform, by connecting to different servers through VPN, we can get more video resources. Although there are many commercial VPN services available on the market, and some free VPNs can also be tried, you need to pay attention to its reliability and security when choosing a VPN. I hope that by using VPN, we can enjoy more streaming content and enrich our lives.

How to buy a VPN in China?

So, how do you buy a VPN in China?

It should be clear that VPN services are prohibited in China due to China's strict Internet censorship system. Some VPN providers that still provide services often use technical means to bypass the blockade. Therefore, when purchasing a VPN, we need to carefully choose a reliable supplier.

The first step to buying a VPN is to find a reliable provider. Since there are certain legal risks in using VPN in China, we need to choose a verified provider to ensure the reliability and security of its services. Some well-known VPN providers such as ExpressVPN, NordVPN, Surfshark, etc. have a good reputation in China because they provide stable connections and reliable privacy protection.

We need to register an account on the official website of the supplier. The registration process is usually simple and straightforward, and only requires filling in personal information and selecting a service package. Some suppliers also offer a free trial period, which can be used for a period of time before use to evaluate its performance and suitability.

Next, we need to choose the right package. VPN providers usually offer different packages to meet the needs of different users. Generally speaking, the price of a package is related to the quality of service and features it provides. We can choose the right package according to our needs and budget.

After completing the package selection, we need to choose a payment method. VPN suppliers usually provide a variety of payment methods, including bank transfer, Alipay, WeChat Pay, credit card, etc. We can choose the payment method according to our preferences and convenience.

After the payment is completed, the supplier will provide us with a download link or QR code for downloading the VPN application. Some applications provided by suppliers may not be available for direct download in China. We can obtain the download link through other channels or download it through free VPN.

Once the VPN application is downloaded and installed, we need to follow the guide provided by the provider to set it up. Generally speaking, the setup process is very simple and only requires entering account information, selecting a server and related parameters. After the setup is completed, we can use the VPN to access blocked websites and applications.

In addition to purchasing a VPN, there are also some free VPN providers to choose from. We need to know that free VPN providers usually have some limitations and disadvantages. For example, the servers of free VPNs may be unstable and slow; data transmission may not be secure enough and there is a risk of leakage. Therefore, if we have the conditions, it is recommended to purchase a paid VPN service to ensure the user experience and privacy security.

In summary, although there are certain legal risks in purchasing VPN in China, by choosing a reliable supplier and complying with local laws and regulations, we can safely use VPN to break through network blockades and browse the Internet. The process of purchasing a VPN requires careful selection of suppliers, registration of an account, selection of a package, completion of payment, downloading and setting up of the application. We can also choose a free VPN, but we need to pay attention to its limitations and security.

What is a VPN?

VPN is the abbreviation of Virtual Private Network, which means virtual private network in Chinese. So, what is VPN?

VPN is a technology that establishes a private connection through a public network. It protects the data transmitted by users on the network from being stolen and spied on by creating a secure encrypted channel between users and servers. In simple terms, VPN is like an encrypted tunnel that allows users to communicate and transmit data securely on the Internet.

VPN can provide us with an anonymous network environment. Some Internet software (ISP) and institutions may track users' Internet activities and collect users' personal information, which is a huge threat to privacy protection. By using VPN, we can hide our real IP address, and all network activities will be forwarded through the VPN server instead of directly connecting to the target website, which can effectively protect our personal privacy.

VPN can help us break through network blockades. In some countries or regions, government departments often block specific websites, which prevents users from accessing some useful information and resources. By using VPN, we can bypass the blockade and freely access blocked websites and applications by connecting to servers in other countries. This is very useful for users who need to bypass the firewall to access foreign resources.

At the same time, VPN can also help us protect the security of our data. When using public wireless networks, we often face the risk of data theft and network attacks. Hackers can obtain users' sensitive information by sniffing network traffic, resulting in personal and property losses. By using VPN, we can encrypt the network connection so that hackers cannot decrypt the data, thereby effectively preventing data leakage and attacks.

Of course, in addition to paid VPN services, there are also many free VPN providers on the market. Free VPNs can play a certain role in protecting personal privacy and breaking through network blockades, but there are also some potential risks. Some free VPNs may make profits through advertising, user traffic, etc., so they will display advertisements or monitor the user's network traffic during user use. The server quality of some free VPNs is often not as stable and reliable as that of paid VPNs, and there may be frequent disconnections and slow network speeds. Therefore, you need to be cautious when choosing to use a free VPN and choose a reputable manufacturer.

In general, VPN, as a virtual private network technology, can provide us with a safe, anonymous and free network environment. It can protect personal privacy, break through network blockades, and prevent data leaks and attacks. When using it, we can choose a paid VPN service or a free VPN, but we need to pay attention to choosing a suitable free VPN and pay attention to protecting the security of personal information.

How to choose VPN software?

Faced with the numerous VPN providers and software with various functions on the market, how to choose a VPN software that suits you has become an important issue. This article will introduce you to how to choose a VPN software from several perspectives.

The first point is security. Security is one of the most important factors when choosing VPN software. A good VPN software should provide advanced encryption technology, such as AES-256 bit encryption, to protect the security of your personal information and privacy. VPN providers should have a strict privacy policy that clearly guarantees that your network activity logs will not be recorded. To ensure security, it is recommended to choose providers with a good reputation, such as NordVPN, ExpressVPN, etc.

The second point is the diversity of server locations. The working principle of VPN is to hide your real IP address by connecting to VPN servers located in other countries, so as to achieve the purpose of circumventing the firewall. Therefore, it is very important to choose a provider with many servers and a wide distribution. Diverse server locations can provide better network connections and more access options. For users who need to access blocked websites in specific regions, the diversity of server locations is a very important consideration.

The third point is speed and stability. Choosing a fast and stable VPN software can ensure your experience of circumventing the firewall. A good VPN should have high-speed servers so that you can smoothly access blocked websites, watch HD videos or play online games. At the same time, a stable connection is also very important so that you don’t get disconnected frequently.

The fourth point is the user-friendly interface. The user interface should be simple, intuitive, and easy to use. The VPN software’s setup and connection process should be easy to operate, and not confusing even for users without technical knowledge. Some excellent VPN providers also provide cross-platform applications, making it convenient for users to use on different devices.

In general, choosing a VPN that suits you needs to consider multiple factors, such as security, diversity of server locations, speed and stability, and user-friendly interface. We remind you to be cautious when choosing some free VPN software. Although some free VPNs may provide basic privacy protection and firewall-breaking functions, some free VPNs may collect and sell your personal data without your knowledge. Therefore, when choosing a VPN, it is best to choose a reliable and trusted supplier, even a paid VPN service is an option worth considering.

In conclusion, I hope this article can provide you with some useful information so that you can choose the right VPN for you among the many VPN software. Remember, security, server location diversity, speed and stability, and user-friendly interface are all important considerations. I wish you a happy VPN experience, access to the blocked websites you want, and protect your online privacy.

Is it illegal to use a VPN in China?

VPN technology can achieve anonymity and privacy protection for users on the Internet. However, in China, the use of VPN has become a controversial behavior.

China has always strictly managed the Internet, including blocking some foreign websites and restricting freedom of speech. In order to maintain national security and stabilize social order, China has also managed and restricted the use of VPNs. According to relevant laws and regulations, the unauthorized use of VPNs is illegal.

In fact, the use of VPNs is very common in China. Many people use VPNs to access blocked foreign websites, watch international movies and TV shows, and enjoy Internet freedom. This phenomenon mainly occurs because VPNs have a certain degree of anonymity, allowing users to circumvent surveillance and censorship. Although the government has taken a series of measures to crack down on the use of VPNs, free VPNs are still emerging in an endless stream.

Free VPN refers to VPN software that provides free services. The emergence of free VPN provides a way to break through the blockade for those who are unwilling to spend money. Many free VPNs have many problems, such as slow speed, instability, many advertisements, privacy leakage, etc. These problems make many users dissatisfied and turn to paid VPN services.

On the other hand, some people believe that the use of VPNs is legal and reasonable in certain specific situations. For example, companies use VPNs for remote work to protect the security and privacy of internal data; students use VPNs for study and research to break through the school's restrictions on Internet access; and multinational companies use VPNs to meet business needs in order to achieve cross-border communications and data transmission. In these cases, the use of VPNs is not illegal.

It is undeniable that the use of VPN also has some potential risks. Some criminals may use VPN to carry out illegal activities, such as spreading illegal information, conducting network attacks, etc. These behaviors seriously threaten national security and social order. Therefore, strict management and supervision of the use of VPN is necessary.

For ordinary users, how to use VPN within the legal scope is a question that needs to be considered. Of course, using a paid and regular VPN service is a safer choice. Paid services can provide more stable and faster network connections while also ensuring privacy and data security. Users must also abide by relevant national laws and regulations and not use VPN to engage in any illegal activities.

There is no simple answer to whether it is illegal to use a VPN in China. From a legal perspective, it is illegal to use a VPN without authorization. But the reality is that VPN use is very common in China, and free VPNs are also emerging in an endless stream. For ordinary users, it is a wise choice to choose a suitable paid VPN service and use it within the legal scope. While protecting personal privacy and breaking through network blockades, it is also necessary to comply with relevant national laws and regulations.

In short, the use of VPN in China involves many issues such as personal privacy and national security. Although the government's management of VPN is relatively strict, free VPN and legal use of VPN still exist. For ordinary users, it is wise to choose a regular paid VPN service and use it within the legal scope. At the same time, the government should also strengthen the management and supervision of VPN to ensure national security and social order.

What are the VPN protocols for circumventing the firewall?

For some reasons, some countries block certain websites and services, which prevents users from freely accessing information and obtaining the required resources. In this case, users can use VPN protocols to bypass the blockade and access the restricted content. The following will introduce several common VPN protocols.

The first is PPTP (Point-to-Point Tunneling Protocol). PPTP is a commonly used VPN protocol that uses a common data link layer protocol to create a virtual point-to-point connection for encryption and privacy protection. PPTP supports a variety of operating systems and devices and is easy to set up and use. However, due to its low security and vulnerability to hacker attacks, it is not recommended for use in some highly confidential situations.

Next is L2TP (Layer 2 Tunneling Protocol). L2TP is a VPN protocol that combines PPTP and Cisco's L2F (Layer 2 Forwarding) protocol. It provides a higher level of security and data integrity. L2TP uses IPSec (IP Security Protocol) for encryption and interoperability between multiple operating systems and devices. L2TP is slightly more complicated to set up and configure, and may be difficult for some non-technical people.

There is also the OpenVPN protocol. OpenVPN is an open source SSL/TLS VPN solution that can be used on a variety of operating systems and devices. OpenVPN uses the SSL/TLS protocol for encryption and authentication, providing a higher level of security and reliability. It also supports both TCP and UDP transmission protocols, which has a wider range of applications. OpenVPN is widely adopted in both commercial and personal use, and its reliability and flexibility are highly praised.

In addition to these common VPN protocols, there are some other protocols to choose from. For example, SSTP (Secure Socket Tunneling Protocol) is a protocol developed by Microsoft, mainly used to provide secure remote access on Windows operating systems. IKEv2 (Internet Key Exchange Version 2) is another newer protocol that provides efficient secure connections through IPSec encryption and authentication.

For those who want to use VPN for free, there are also some free VPN software. Free VPN services usually have limitations, such as speed limits, traffic limits, or ad interference. The options for free VPN protocols are also limited, and most free VPN software uses PPTP or L2TP protocols. Because the reliability and security of free VPN services may be risky, you need to be cautious when using them.

In summary, VPN protocols include PPTP, L2TP, OpenVPN, etc. Each protocol has its own advantages and applicable situations, and users can choose the appropriate protocol according to their needs and technical level. For those who pursue a higher level of security and stability, it is recommended to choose a paid VPN service, while for users who only need to bypass the firewall occasionally, free VPN services are also an option. Whether it is a free or paid VPN service, users should be vigilant, choose a trustworthy provider, and comply with local laws and regulations.

How to purchase, install and use VPN?

It can hide the user's IP address, protect the user's privacy and security, and provide a more stable and high-speed network connection. Many people want to buy, install and use VPN to better protect their privacy and access restricted websites. So, here is how to buy, install and use VPN.

The first step in buying a VPN is to choose a reliable VPN software. There are many free and paid VPN providers on the market, but to ensure the quality and security of the service, paid VPNs are usually more reliable. When choosing, you can refer to user reviews, professional reviews, and recommendations from review websites. Some well-known VPN providers include ExpressVPN, NordVPN, and Surfshark.

After purchasing a VPN service, you need to install it according to the provider's requirements. Most VPN providers have client software for different operating systems, such as Windows, MacOS, Android, and iOS. During the installation process, users need to pay attention to the security when downloading software and only download from the official website to prevent downloading malware.

Once the installation is complete, you will need to enter the credentials you provided when you purchased the VPN to log in. These credentials are usually a username and a password, which you should keep safe and not disclose to anyone else.

Next, users can choose a suitable VPN server to connect to according to their needs. VPN service providers usually have many servers distributed around the world, and users can choose a server closer to them to get faster Internet speeds. If users need to access websites or services in a specific country, they can choose a server in that country to connect to.

After connecting to a VPN server, the user's network traffic will be transmitted through an encrypted channel to protect privacy and bypass geographical restrictions. Users can browse the Internet safely, access blocked websites and services, hide their IP addresses, and prevent information leakage on public Wi-Fi.

For some users, they may be more concerned about free VPN services. Although free VPN services have certain limitations, such as bandwidth restrictions, slow speeds, and a limited number of servers, for some light users, free VPNs can also meet their basic needs. Some well-known free VPN service providers include Hotspot Shield, Windscribe, and TunnelBear. Users can choose a free VPN that suits them.

In short, buying, installing, and using a VPN is not complicated. By choosing a reliable VPN provider, following the instructions to install and connect to the server, users can easily enjoy the VPN-enabled scientific Internet access and privacy protection. Whether buying a paid VPN or choosing a free VPN, users need to make a choice based on their needs and budget. I hope this article can help those who are interested in buying, installing, and using a VPN.

What are VPNs used for?

It is an encrypted communication technology that protects users' online privacy and security by establishing an encrypted tunnel over a public network. The use of VPNs is becoming more and more popular, and its uses are very wide. This article will explore the uses of VPNs.

On the one hand, VPN can be used to protect personal privacy. In today's digital age, the problem of personal privacy leakage is becoming more and more serious. The emergence of various cutting-edge technologies and network hackers has brought huge risks to users' privacy security. However, by using VPN, users can hide their IP addresses and online behaviors, making their personal information less likely to be stolen and tracked. At the same time, VPN can also encrypt users' data and communications to ensure that users' privacy is not eavesdropped or tampered with. Based on these advantages, more and more people are beginning to use VPN to protect their online privacy.

On the other hand, VPN can be used to break through network restrictions. In some regions or countries, the government restricts users from accessing specific websites and applications through technical means such as network blocking, censorship and filtering. This has caused troubles for users in terms of information acquisition, free expression, study and work. By using VPN, users can bypass these restrictions and access blocked websites and applications. Because VPN can change the user's IP address and virtual location, users can get a free Internet experience by connecting to servers in other countries. Especially in some areas where network neutrality and freedom of speech need to be maintained, the use of VPN becomes particularly important.

VPN can also be used to protect the security of public Wi-Fi networks. Public Wi-Fi networks generally have poor security issues, and hackers can steal users' personal information through eavesdropping and deception. When using VPN, users can protect the secure transmission of data through encrypted communication tunnels, reducing user risks. Especially for people who often surf the Internet in public places, using VPN has become an essential security tool.

VPNs have other uses. For example, for multinational companies, they can use VPNs to achieve secure connections between different office locations, facilitating file sharing and remote work among employees. Some gamers also use VPNs to solve game region restrictions and reduce network latency. VPNs can also be used to bypass traffic restrictions on some websites and increase network access speeds.

Finally, I would like to mention free VPNs. Although there are many paid VPN service providers on the market, there are also some options that provide free VPNs. Free VPNs may have some limitations, such as slow speed, many ads, unstable connection, etc. But for some simple web browsing and personal privacy protection needs, which do not require high performance, free VPNs are sufficient. It’s just that when choosing a free VPN, users need to pay more attention and choose a brand with reputation and credibility to ensure safety and reliability during use.

In general, VPN has a wide range of uses. It can protect personal privacy, break through network restrictions, increase the security of public Wi-Fi networks, and has other special uses. With the development and popularization of the Internet, the importance of VPN has become increasingly prominent. Whether it is an individual user or a corporate user, using VPN can effectively improve the scientific Internet access and privacy protection.

What should I pay attention to when using a VPN?

Although VPN can provide users with a safe and anonymous Internet experience, you still need to pay attention to the following aspects when using VPN to bypass the firewall.

Choose the right VPN software. There are many different VPN software available on the market, some are free, while others require a fee. Although free VPN services save money, we should also be aware that free VPNs may limit your bandwidth, speed, etc., and often display ads on your device. Free VPNs may not be safe enough, and they may record your online activities, which is exactly contrary to the original intention of using a VPN. Therefore, if you have high requirements for scientific Internet access, it is recommended to purchase a paid VPN service.

Ensure the legality of the VPN. In some countries, using a VPN to bypass the firewall may be illegal and may cause legal risks to you. Therefore, before using a VPN, make sure whether the use of VPNs is allowed in your country or region. If it is illegal, it is strongly recommended to comply with local laws to avoid unnecessary disputes.

Protecting personal privacy is also an important aspect to pay attention to when using VPN. Although VPN can help us surf the Internet anonymously, we must make sure that the VPN we choose does not record the user's surfing data to avoid the risk of personal privacy leakage. When choosing VPN software, be sure to read their privacy policy carefully to ensure that they do not record or monitor user data.

Be cautious about the advertising information sent by some free VPN providers. Some bad VPN service providers will send a lot of advertising information to make profits, and even sell users' personal information to third parties. Therefore, when downloading and installing VPN applications, choose a reliable publisher and carefully review the permission request.

When using VPN, you should also pay attention to the occasions of use. When using VPN, we should avoid using it in situations where we need to enter sensitive information such as bank account numbers and passwords to avoid the risk of hacker attacks and personal information leakage. When using VPN, you should try to avoid connecting to untrusted Wi-Fi networks to prevent hackers from stealing your Internet data.

Finally, in order to get a better user experience, it is also important to choose a VPN service provider with good service quality. You can choose a stable and fast VPN service by reading user reviews, looking for recommendations or consulting professionals.

In summary, when using VPN to break through network restrictions, you need to pay attention to the selection of appropriate VPN software, ensure the legality of VPN and protect personal privacy, be cautious about advertisements in free VPN, choose appropriate usage occasions, and choose VPN service providers with good service quality. Only by considering the above factors can we better use VPN to break through network restrictions and ensure that our VPN is scientific and our personal privacy is not violated.

Which VPN nodes have fast connection speeds?

Since VPN traffic encryption and forwarding require certain bandwidth and server resource support, some VPN nodes have slow connection speeds. So, which VPN nodes have fast connection speeds? The following will analyze several angles to answer this question for you.

Which is better, paid VPN or free VPN?

For some users with specific needs, VPN can protect their privacy, unlock regional restrictions, and ensure scientific Internet access. Faced with many VPN services, users often face a difficult problem: should they choose a paid VPN or a free VPN? Let's discuss this issue below.

Let's look at security. Generally speaking, paid VPNs offer better security. Paid VPNs usually have their own servers and regularly maintain and upgrade them to ensure the security of the network. Free VPNs, however, may sacrifice security in exchange for a larger number of users due to limited resources. Some free VPNs may embed ads or collect user data, which poses a certain threat to user privacy. Therefore, from a security perspective, paid VPNs are more worthy of choice.

Network speed is also an important factor that users need to consider when choosing a VPN. Since paid VPNs have more resources invested and more advanced technical support, they generally have faster network speeds. After all, users pay and naturally expect to get better services. Free VPNs may cause network congestion and slow down the network speed due to the large number of users. Especially during peak hours, the speed of free VPNs is even more unsatisfactory. Therefore, if users are looking for faster network speeds, paid VPNs are a good choice.

The number of servers and geographic location are also factors to consider. Paid VPNs usually have multiple servers around the world, and users can choose different servers as needed to better unlock regional restrictions and access overseas websites. Free VPNs may only provide limited servers due to limited resources, and users may be restricted when accessing websites in certain specific regions. If users need to frequently visit overseas websites or need to use VPNs across regions, the number of servers and geographic location of paid VPNs are a clear advantage.

Finally, it is also important to note that paid VPNs usually provide better customer support and after-sales service. If users encounter problems or have any needs, they can directly contact customer service staff through phone, email, online chat, etc. Free VPNs usually only provide basic technical support, and users may only be able to seek help through forums or communities when they encounter problems. For some users who are not familiar with network technology, the customer support of paid VPNs undoubtedly provides greater convenience.

In general, paid VPNs and free VPNs have their own advantages and disadvantages. In terms of security, network speed, number of servers, customer support, etc., paid VPNs are better. Of course, if users only need to use VPN occasionally, do not have high requirements for security and speed, or are dissatisfied with the pricing of paid VPNs, free VPNs can also be an option. Ultimately, users can weigh the pros and cons based on their own needs and conditions and choose a VPN service that suits them.

What are the VPN security features?

It can provide a variety of security features, making users safer and more assured in the online world. The following will introduce the security features of VPN in detail.

VPNs protect the security of user data through encryption technology. When a user connects to a VPN server, the VPN automatically encrypts the transmitted data. This means that even if a hacker steals the transmitted data, it cannot decrypt its contents. This powerful encryption technology ensures the privacy and data security of the user.

VPNs can hide your IP address. Every device on the internet has a unique IP address that can track your online activities. But by connecting to a VPN, your real IP address is hidden and the VPN server's IP address is used. This makes your online activities untraceable, increasing anonymity and privacy.

VPNs are also able to bypass geographic restrictions and access restrictions. Certain countries or regions restrict access to specific websites, applications, or services. By connecting to a VPN server located in another country, users can bypass these restrictions and access blocked content. This provides users with greater freedom and convenience.

Another important security feature is that VPNs protect against the risks of public Wi-Fi. Public Wi-Fi networks are often targeted by hackers because they often lack security protections. When you connect to a public Wi-Fi network using a VPN, your data will be encrypted, making it impossible for hackers to steal sensitive information, ensuring online security.

At the same time, free VPNs are also one of the options for safe Internet access. Although free VPNs may have limited features and speeds, the encryption and IP hiding features they provide can still provide users with a certain degree of online security. But be aware that it is important to choose a trustworthy free VPN provider to ensure that the user's privacy and data security will not be compromised.

In addition to the above functions, VPN can also prevent ISP (network software) from tracking users' online activities. In some cases, ISPs may record users' browsing history and sell it to third-party companies, thereby infringing on users' privacy. After using VPN, users' data traffic will be encrypted by the VPN server, and ISPs will not be able to track users' online activities, thus improving users' privacy protection.

Finally, VPN is also widely used in business environments. Many companies use VPN to ensure the security of employees when they remotely access the company's internal network. Employees can remotely connect to the company's internal resources through VPN, and use encryption technology to protect the secure transmission of data to prevent hacker intrusion and data leakage.

In general, VPNs offer a variety of security features, including data encryption, IP hiding, bypassing geographic restrictions, preventing public Wi-Fi risks, free options, preventing ISP tracking, and use in business environments. Both individual users and businesses can benefit from the security features of VPNs to ensure the privacy and security of online activities.

Why can’t I watch TikTok even if I use a VPN?

Many people have found that even with the use of tools such as a virtual private network (VPN), they still cannot access TikTok. Why can't you watch TikTok even if you've climbed over the Great Firewall? Here we discuss this from several different angles.

This phenomenon may be due to the restrictions on VPNs on the TikTok platform itself. Because some countries have expressed concerns about TikTok, believing that it involves issues such as user privacy and national security, they have restricted users' access to TikTok by blocking VPNs. Although in some cases, this blockade can be circumvented by changing VPN servers or using paid VPN services, it may only be a temporary solution to the problem.

The TikTok platform may have taken some technical measures to prevent illegal access through VPN. On the one hand, TikTok may detect the authenticity of the user's IP address and filter out some widely used free VPN servers, resulting in inability to access normally. On the other hand, TikTok may also use other means to identify VPN connections and block access by related users. The existence of this technical means makes it very difficult to access TikTok through VPN.

Some possible user configuration issues may also result in the inability to access TikTok after circumventing the firewall. For example, some users may not correctly configure the relevant parameters when setting up the VPN, resulting in an inability to connect to the TikTok server. Some free VPN services may not be able to provide a stable connection due to heavy server load or bandwidth restrictions, making it difficult for users to access TikTok smoothly. In this case, users can try to change the VPN server, or consider using a paid high-quality VPN service.

The user's geographic location may also affect their access to TikTok. The TikTok platform may provide different content and services based on the user's geographic location. If a user changes their location to another country or region through a VPN, they may not be able to access TikTok content in a specific geographic region. In this case, the user can try using a different VPN server to set their location to a geographic region accessible by TikTok.

In summary, the inability to access TikTok after circumventing the firewall may be due to a variety of reasons. The TikTok platform's own restrictions on VPNs, the use of technical means, user configuration issues, and geographic location factors may all cause this phenomenon. Although some users can solve the problem by changing VPN servers or using paid VPN services, it does not guarantee that they will be able to successfully access TikTok. In any case, we should respect the regulations of various countries on network use and content control, and enjoy network resources on the premise of legality and compliance.

What does it mean to climb over the wall?

It is also a way to circumvent blockades and censorship. Climbing the firewall may be very common in some regions, such as mainland China and Iran.

Why do we need to circumvent the Great Firewall? The most common situation is that the government or institutions impose strict restrictions and censorship on the Internet to control the flow of information and maintain social stability. These restrictions can cover different areas, such as freedom of speech, news reporting, social media, movies, music and other aspects of content. Circumventing the Great Firewall is to bypass these restrictions by using specific tools or services to gain free access to the Internet.

Of course, circumventing the firewall is not always necessary to access blocked content or bypass censorship. It can also be used for the purpose of circumventing the firewall and privacy protection. For example, public Wi-Fi networks often have security risks, and hackers can easily steal users' personal information. Using circumvention services, users can encrypt their data traffic and improve their circumvention of the firewall. In some countries, personal privacy protection is weak, and circumvention can also be used as a way to protect personal privacy from surveillance and infringement.

There are many tools on the market that provide wall-breaking services, and free VPN is one of them. VPN is the abbreviation of Virtual Private Network, which is a technology that creates an encrypted tunnel in a private network through a public network. With VPN, users can transfer their Internet traffic through a VPN server, thereby hiding their real IP address, bypassing geographical restrictions, and accessing blocked websites and applications.

Free VPN refers to a VPN provider that provides free services. Although some free VPNs provide basic functions, they usually limit the bandwidth, server selection, network speed, etc. Some free VPN service providers may also track users' online activities and sell users' personal data for profit. Therefore, it is very important to choose a free VPN service provider that is trustworthy and has a good reputation.

Using a VPN is not a perfect solution. Some countries and Internet software have restricted the use of VPNs or even blocked VPN services. Using a low-quality free VPN may lead to unstable connections, slow speeds, and privacy leaks. Therefore, it is crucial to understand and comply with the relevant laws and regulations of the country and region.

In short, circumvention is the act of breaking through network restrictions by using tools or services to access blocked or restricted websites and applications. It can be used to access censored content, improve the scientific nature of circumvention, and protect personal privacy. Free VPNs are one way to achieve circumvention, but users should choose carefully and abide by relevant laws and regulations. We hope that there will be more developments in the future that make the Internet a truly free and open place.

Is it still possible to circumvent the firewall in China now?

Climbing the firewall refers to using technological means to break through the restrictions of the domestic network and access blocked external websites. Is it still possible to climb the firewall in China now?

Let's talk about the necessity of circumventing the firewall. With the development of the domestic network, more and more people have begun to use the network as an important channel to obtain information and understand the world. Due to certain policies, some external websites cannot be accessed in China. These blocked websites include some social media platforms, news websites, etc. For those who want to understand the outside world, circumventing the firewall is essential.

Let's take a look at some ways to get around the firewall. Currently, the most common method is to use a virtual private network (VPN). A VPN is a tool that can encrypt your network connection and hide your real IP address. By connecting to a VPN server, you can bypass domestic network restrictions and access blocked websites. Moreover, there are many free VPNs available on the market, and users can install these free VPN software to get around the firewall.

As for whether it is still possible to bypass the firewall in China, the answer is that it is somewhat difficult. Currently, China's supervision of VPNs is becoming increasingly strict. Some well-known VPN service providers have been forced to shut down in China. As a result, many people have found that the VPNs they used before can no longer be used normally. Moreover, free VPNs also face the problem of being blocked or unable to connect.

Despite this, there are still some ways to continue to circumvent the firewall. You can try using a paid VPN service provider. Paid VPN service providers are relatively more reliable in terms of stability and speed, and have certain technical support. You can use some other technological means to access blocked websites, such as setting up a proxy server or using a foreign DNS resolution service.

There are also ways to circumvent the problem of VPN being blocked. Some users choose to build their own VPN servers to avoid using public VPN services. Although this requires certain technical knowledge and costs a certain amount of money, it can better protect the privacy and security of users. Some technology companies and developers are also constantly researching and developing new wall-breaking tools to deal with the blocking problem.

In short, although it is becoming increasingly difficult to circumvent the firewall in China, there are still some ways to do it. Using a paid VPN service provider or trying other technological means may be a more feasible option. Of course, circumventing the firewall must comply with the bottom line of law and morality, and pay attention to the scientific Internet access and personal privacy protection. Only after fully understanding the relevant risks and precautions can we better use circumvention to obtain information and understand the outside world.

Is it illegal for personal use of VPN?

There is always a debate about whether VPN use is legal. In some countries, there are government restrictions on VPN use, while in other countries, personal use of VPNs is allowed and encouraged.

Let's look at different opinions on whether personal use of VPNs is illegal. Some governments believe that VPNs can be used to bypass national restrictions on Internet access or to engage in criminal activities, such as online fraud, illegal downloading, etc. Therefore, these countries have taken measures to restrict or ban the use of VPNs to ensure scientific Internet access and social order. Using a VPN in such a country may be considered an illegal act and may face legal risks and penalties.

The governments of other countries are open to the use of VPNs by individuals. These countries believe that VPNs help maintain personal privacy rights and data security. In these countries, the use of VPNs is allowed and encouraged, and people can use VPNs to protect their online privacy, access restricted websites, or conduct secure online transactions on public wireless networks. Such countries do not consider personal use of VPNs to be illegal, on the contrary, they believe that it is a protection of personal rights.

So, how can an individual use a VPN legally in a country where personal use of a VPN is considered illegal? One way is to look for a free VPN service. Free VPN services may be banned in these countries, but in reality, many people still choose to use free VPNs to protect their online privacy. Whether it is dealing with government internet restrictions or conducting secure online transactions, free VPNs can provide certain protection. Although there are some problems with free VPNs, such as slow speeds, data restrictions, advertisements, etc., they may be a viable solution for individuals.

When using a free VPN, individuals should also pay attention to some issues. Free VPN software should be carefully selected to ensure its credibility and reliability. It is important to understand that free VPNs may collect and monitor personal data, which poses a privacy and security risk. Therefore, when using a free VPN, individuals should try to avoid operations involving sensitive information and try to protect their privacy.

In general, the legality of using VPNs by individuals depends on the laws, regulations and policies of the country in which they are located. In some countries, using VPNs may be considered illegal and may result in legal risks and penalties. In other countries, using VPNs is allowed and encouraged, and people can use VPNs to protect their online privacy and data security. For individuals, when using VPNs, they should choose appropriate VPN software and pay attention to protecting their personal privacy. Although there are some problems with free VPNs, they may be a viable solution for individuals with specific needs. With a full understanding of the risks, individuals can choose to use VPNs in a way that suits them to protect their online security.

Does using a VPN consume my data?

Some people have doubts about whether using a VPN will consume their own data traffic. So, let's look at whether using a VPN will consume your own data traffic from different perspectives.

Let's take a look at how VPN works. VPN establishes an encrypted tunnel to transmit the user's network data from the local device to the VPN server, and then the VPN server sends it to the target website on behalf of the user. In this process, VPN will encrypt and decrypt the user's data, which requires a certain amount of computing resources and bandwidth. Therefore, from this perspective, using VPN does consume a part of your own traffic.

Let's take a look at free VPNs. Although free VPNs are free, they do have some hidden costs, one of which is data usage. Since free VPNs have limited resources, they usually limit data usage and bandwidth in order to provide free services. This means that when using a free VPN, you may experience lower speeds and limited data usage. So, if you use a free VPN to watch HD videos or download large files, your data usage may be consumed quickly.

Another thing to consider when using a VPN is network latency. Since VPNs need to transfer data to a server and then send it to the target website, this process will increase network latency. This is especially true when using a server that is farther away. This means you have to wait longer before you can open a web page or perform other network operations. Therefore, using a VPN will indirectly consume your traffic because you have to spend more time waiting for data to be transferred.

You may also encounter privacy issues when using a VPN. Although VPNs can encrypt users' network data and protect their privacy and security, not all VPNs are trustworthy. Some free VPNs may collect users' personal data behind the scenes and sell it to third parties. This means that your personal privacy may be violated. Therefore, when choosing to use a VPN, be sure to choose trustworthy software to avoid losing personal information due to using an unsafe VPN.

In general, it is a fact that using a VPN will consume your own traffic. Whether it is the data encryption and decryption process through the VPN or the traffic and bandwidth restricted by using a free VPN, it will have a certain impact on the user's traffic. Using a VPN may also increase network latency and pose privacy risks. Therefore, when using a VPN, we need to weigh the pros and cons and choose a suitable VPN service according to our actual needs in order to better protect our scientific Internet access and privacy.

Why can't I connect to VPN?

Sometimes we may encounter the problem that VPN cannot connect, so what is the reason?

VPN failures may be caused by network issues. For example, if your network environment restricts the use of VPNs, you will not be able to connect to the VPN server. Some regions have restrictions on VPNs, especially in some countries where the government blocks some VPN services. If your network signal is unstable, it may also cause connection problems. Some free VPN services have unstable quality and may not be able to connect.

VPN failure may also be caused by VPN server failure. The VPN software's server may be unable to connect due to maintenance, upgrades, or other problems. If you are using a free VPN service, you are more likely to encounter such a problem because the free VPN's server may be unstable. To avoid this problem, it is recommended to choose some well-known paid VPN service providers that can provide a more stable connection.

There may also be issues with your VPN client causing the connection to fail. If your VPN client software is outdated or incorrectly configured, it will not be able to connect to the VPN server properly. At this point, you need to check that you are using the latest version of the VPN client and make sure the configuration information is correct. Sometimes, even the latest version of the VPN client can cause connection problems, which may be because your operating system is not compatible with the VPN client. If this is the cause of the problem, you can try installing a different VPN client that works with your operating system.

Another common problem is the VPN account. Some free VPN providers may limit the user's connection speed, data traffic, or online time. When the limit is exceeded, you will not be able to connect to the VPN server. This requires you to check whether your VPN account exceeds the limit and close unnecessary connections in time, or choose to use a paid VPN service to get an unlimited experience.

Finally, user error is also a reason why VPNs cannot connect. Sometimes, we may enter the wrong server address, username, or password, which will prevent us from connecting to the VPN server. When using a VPN, be sure to carefully check and enter the relevant information correctly to ensure a successful VPN connection.

Before we end, let me mention free VPNs again. Although free VPNs provide certain conveniences for users, there are also some hidden dangers due to their free nature. Some free VPNs may record users' online activities and sell this information to advertisers or third parties. Free VPN servers are prone to abuse, leading to network congestion and instability. Therefore, in order to ensure a secure and stable network connection, it is recommended to choose a paid VPN service.

Generally speaking, the reasons why VPN cannot connect may involve network restrictions, VPN server failures, VPN client problems, account restrictions, and user operation errors. To solve this problem, we need to carefully investigate and take corresponding solutions according to the specific situation. In any case, choosing a stable and reliable paid VPN service is the best choice to ensure scientific and smooth Internet access.

What are the scientific ways to surf the Internet?

With the development of the Internet, the demand for scientific Internet access is also growing. So, what are the ways to surf the Internet scientifically? Below, I will introduce them to you.

We can use VPN (Virtual Private Network) to surf the Internet scientifically. VPN is a method of creating a private network through a public network. It achieves privacy and data transmission security between users and the Internet through technical means such as encrypted communication, identity authentication and access control. VPN software is widely available, and there are some free VPN services. Free VPN is suitable for some simple browsing and communication needs, but the speed may not be fast enough and the traffic may be limited.

We can use Shadowsocks to surf the Internet scientifically. Shadowsocks is a lightweight proxy tool that is widely used in wall-climbing technology. It uses the Socks5 protocol and obfuscation technology to achieve more efficient data transmission. Shadowsocks is characterized by high speed, high stability, and is not easily blocked. However, it should be noted that using Shadowsocks requires a stable server and configuring it.

In addition to VPN and Shadowsocks, we can also use proxy servers to surf the Internet scientifically. Proxy servers act as a middleman, communicating with the target website on our behalf, hiding our real IP address and achieving the effect of scientific Internet access. Using a proxy server can be achieved by modifying the proxy settings of the browser, or by downloading some proxy software. However, the proxy server may be blocked or have a limited number of uses.

Another scientific way to surf the Internet is to use a DNS (Domain Name System) pollution solution. DNS pollution means that when we visit a blocked website, the domain name resolution is tampered with and cannot be correctly resolved to the correct IP address, making it impossible to access the target website. In order to solve this problem, some DNS service providers have provided solutions that can help us bypass DNS pollution and access blocked websites.

To sum up, there are many ways to surf the Internet scientifically, such as VPN, Shadowsocks, proxy servers, and DNS pollution solutions. Different methods are suitable for different needs and environments. If you want to surf the Internet scientifically for free, you can try some free VPN services, but pay attention to possible speed and traffic restrictions. If you want a more stable and fast Internet experience, you can consider using a paid VPN, Shadowsocks, or proxy server. Of course, for some people with a higher level of technology, building a VPN server or Shadowsocks server of your own is also a good choice. No matter which method is used, we must use it legally and compliantly, and pay attention to surfing the Internet scientifically and protecting personal privacy. I hope that through these methods, everyone can enjoy a free and unobstructed Internet world.

Which scientific Internet access is better?

When choosing a scientific Internet access tool, users often face a question: Which scientific Internet access tool is better?

We can consider it from two aspects: user experience and stability. The primary concern of many users for scientific Internet tools is stability. After all, no one wants to have slow Internet speeds or frequent disconnections due to unstable networks.

Some well-known free VPN providers, such as Windscribe, Hotspot Shield, etc., provide relatively stable network connections, and also have a free basic package for users to choose.

We can also consider it from the perspective of privacy protection. In the process of scientific Internet access, the user's personal privacy also needs to be protected. Some free VPN providers may collect users' personal information during use and advertise it. Therefore, when choosing scientific Internet access tools, users need to pay attention to privacy policies and choose trustworthy free VPNs. There are currently some well-known free VPN providers, such as ProtonVPN, TunnelBear, etc., which are committed to protecting user privacy and will not collect user personal information during use.

We can also consider the usability of scientific Internet tools from the perspective of feature richness. Some comprehensive scientific Internet tool providers, such as ExpressVPN, NordVPN, etc., provide more features, such as multiple server nodes to choose from, encryption technology, firewalls, and ad blocking. These features can help users better protect privacy and increase Internet speed. Of course, these paid VPN services can also provide free trials or basic packages for user experience. For those users who just need simple scientific Internet access, some free VPNs also provide relatively basic scientific Internet functions.

In addition to the above perspectives, we can also consider the usability of scientific Internet access tools from aspects such as domestic and foreign network environments and user reputation. In mainland China, due to network censorship and blockades, the demand for scientific Internet access is relatively widespread. Some scientific Internet access tools have better connection quality and faster speed under the Chinese network environment, and also have better support for some special Internet access needs, such as watching Netflix. Users can learn about user evaluations and reputations through search engines, community forums and other channels, so as to choose scientific Internet access tools that are more suitable for them.

In general, choosing a good scientific Internet access tool requires not only stability and user experience, but also privacy protection, feature richness, domestic and foreign network environment, and user reputation. Whether choosing a paid VPN or a free VPN, users should choose a scientific Internet access tool that suits them according to their actual needs and budget. By comprehensively considering these factors, users will be able to find a truly useful scientific Internet access tool.

How to use VPN on Android phone?

Using VPN (Virtual Private Network) is a common way to protect privacy. So how to use VPN on Android phones? Next, we will introduce some methods and precautions for using VPN.

Users can find and download VPN applications by searching for the keyword "VPN" in Google Play or other app stores. There are many VPN applications on the market for users to choose from, such as ExpressVPN, NordVPN, etc. These applications provide a variety of functions and services, and there are also free VPN applications available.

After installing the VPN app, users need to register an account and log in. Some free VPN apps may require users to watch ads or provide personal information before use, so users need to be cautious when using these free VPN apps. Paid VPN apps will provide more stable and secure services.

One of the benefits of using a VPN is that it can hide the user's real IP address and location information, thereby maintaining the user's privacy. By connecting to a VPN server, users can choose a virtual identity to access the network. However, it should be noted that some free VPN applications may have the risk of leaking user data, so it is recommended that users choose some well-known and trusted applications when using VPN.

In addition to protecting user privacy, VPN can also break geographical restrictions and bypass network blocks in certain regions, allowing users to access restricted content. For example, some countries block certain social media or video websites, but by using VPN, users can choose to connect to servers in other countries to bypass the blockade. In this way, users can browse blocked websites or applications freely.

Some VPN applications also provide additional encryption features to protect the security of user data during network transmission. This is very useful for those who often use public Wi-Fi networks. Because public Wi-Fi networks often have security risks, hackers can steal users' personal information and login credentials. Using a VPN can encrypt the user's data traffic and ensure that the user's information cannot be obtained by hackers.

Although VPNs have many benefits in protecting privacy and bypassing blockades, you should also be aware of some issues when using them. Using a VPN will slow down your network because your data needs to pass through the VPN server, and the server may be under a certain load. So when choosing a VPN application, you should pay attention to choosing a professional VPN service that is fast, stable, and secure. Some free VPN applications may frequently display pop-up ads, and users need to endure these interruptions when using them.

In general, using a VPN on an Android phone is a good way to protect privacy and data security. By using a VPN, users can hide their IP address, break geographical restrictions, and encrypt data transmission. Although there are some problems with using a VPN, these problems can be effectively solved if users choose the right VPN app. I hope this article will help you understand how to use a VPN on an Android phone.

Free VPN FAQ

1. Can free VPNs be used in China?

Some free VPNs can still be used in China, but as China's ban on VPNs has been tightened in recent years, a large number of VPNs have become ineffective, and free VPNs have been the most affected. As of now, most free VPNs are no longer usable in China.

Moreover, free VPNs have various restrictions in terms of traffic and speed. Therefore, if you only need to use a VPN to bypass the firewall occasionally, you can still try a free VPN. However, for Chinese netizens who need to bypass the firewall for a long time, free VPNs are unlikely to meet their needs.

2. Can a free VPN be used to bypass the firewall to watch videos on YouTube, Netflix, etc.?

If you want to watch videos on YouTube or Netflix, it is difficult to use a free VPN. On the one hand, a large number of free VPNs are no longer valid in China, so they cannot be used at all.

In addition, free VPNs almost always impose various restrictions on traffic and speed, so it is difficult to achieve smooth video viewing using a free VPN.

3. What is the use of free VPN?

For users in mainland China, free VPNs cannot meet the needs of long-term circumvention, but having one or two free VPNs on hand can be used as an emergency measure. Once the commonly used paid VPN fails, at least you can use a free VPN to circumvent the firewall to find a solution, or register and download a better VPN.

1. First, choose a reliable VPN provider

Before downloading a VPN, it is important to find out which VPN is best for you. This is the most critical step among the three steps above.

If you haven’t made a clear VPN choice yet, you can refer to our best VPN rankings. The VPNs on the list have top performance in security, speed, ease of use, cost-effectiveness, and anonymous purchase.

If you are in mainland China and value the ability to circumvent the firewall and stability, you can refer to our China VPN recommendations.

In short, before choosing a VPN, you must make comprehensive considerations from the following aspects to ensure that there will be no problems in actual use:

• Fast speed: The importance of speed needs no further explanation. If a VPN significantly reduces your bandwidth and blocks your network, you will not have a good experience whether watching TV shows or playing games. If a paid VPN cannot even guarantee this, then why not choose a free VPN.

• Good stability: Good anti-censorship software usually prepares a lot of spare nodes for transition. After the special period is over, it can be quickly restored to use, and a series of operations such as adding server nodes and upgrading anti-censorship software can be performed.

• High security: Outside of China, protecting user privacy and Internet data security is the most important responsibility of VPN. No one wants their privacy to be snooped by ISP or network administrator.

• Strong customer support: If you have 24/7 instant online customer service, you can quickly get effective solutions to any problems you encounter during the process of purchasing and using VPN.

• Many server nodes: The more servers a VPN has, the better its ability to unlock geographical restrictions and the faster its connection speed. Generally speaking, the closer the nodes are to mainland China (Hong Kong, Taiwan, Japan, the United States, etc.), the better the experience.

2. Go to the official website of your chosen VPN to download

Downloading is risky. Some rogue software and even phishing VPNs with viruses will disguise themselves as ordinary VPNs, waiting for you to download them to your phone. So we recommend that you go directly to the official website through the major VPN download addresses we provide below, so as to avoid downloading pirated VPNs to the greatest extent.

Windows VPN Download

• VPN for Windows is relatively convenient and easy to download and install. The official website of most VPN service providers provides the download address of .exe file. You only need to click download to download the VPN installation package to your PC immediately.

Mac VPN Download

• Generally, the official website of VPN service providers that provide Windows installation packages will also provide Mac VPN client downloads. You can also download it through the link of App Store. You can download it with one click. The Apple Store may require you to enter your Apple ID information. In addition, it should be reminded that there is no VPN software available for download in the Chinese region of MacOS App Store.

Android Android VPN Download

• Android has a more open ecosystem, so there are many ways to download it. You can get the Android VPN download address on the service provider's official website, or you can download the VPN Apk installation package from major app stores. Tablets and Android TV devices can also easily get the corresponding installation package.

iOS VPN Download

• Since iOS is closed, only VPN software that has passed the App Store verification can be downloaded. The advantage is that the security of VPN is guaranteed, and there will be no phishing VPNs that copy the logo or name. The disadvantage is that mainland Chinese users can only download normally if they apply for a US ID or other overseas Apple ID. Because all VPN software has been removed from the mainland.

3. Activate and use VPN after installation

The installation process after downloading VPN is the same as other software, so I won’t go into details. Many service providers’ VPNs are also relatively simple and easy to use. You only need to open the connection to the server, then you can log in and activate the software to start using it.

But there is a difference between free VPN and paid VPN. Free VPN can be used directly after downloading, while paid VPN needs to purchase a package plan before use. Next, I will take PrivateVPN as an example to introduce the subscription process after downloading the VPN software. PrivateVPN is an easy-to-use VPN with good Chinese support, which is very suitable for beginners. >View detailed review<

First, go to the PrivateVPN official website and select "Get PrivateVPN" to jump to the purchase page. A digital account will be automatically generated here. You only need to set a password.

Paid VPN software download 1: PrivateVPN download address

PrivateVPN is the VPN that performs best in all aspects in our ranking. Although it is relatively young, its experience optimized for China is outstanding, with fast wall-penetration speed, stable lines during special periods, and more than 3,000 servers around the world.

In general, Panda VPN is one of the best VPNs for overcoming the firewall. Its client VPN software is simple and easy to use, and it also has UK and US IP nodes that can unblock popular overseas websites such as Netflix, Disney+, BBC iPlayer, Hulu, Amazon Prime Video, etc. Most importantly, Panda VPN has the lowest price on the market while maintaining such excellent performance, and it is highly recommended for everyone to use.

Paid VPN software download 2: ExpressVPN download address

ExpressVPN is one of the most well-known VPNs for circumventing the firewall, and it also has many users in mainland China. It has fast speed, stable connection, and great customer service. Most importantly, it provides available server nodes in 94 countries, making it the VPN software with the most connectable regions. In addition, its 30-day money-back guarantee can also protect the rights and interests of users to the greatest extent.

Among all VPN providers, ExpressVPN is one of the few VPNs that can be used in China. Although it is relatively expensive, its 30-day money-back guarantee can also protect the rights of users to the greatest extent. If you have requirements for the number of countries you can connect to, then ExpressVPN is a good choice.

Paid VPN software download three: PureVPN download address

PureVPN is headquartered in the British Virgin Islands, which is not under the jurisdiction of 5 Eyes/7 Eyes/14 Eyes, and there is no log retention in the region, so no government or organization will ask PureVPN to hand over user information. It has many powerful features, including: military-grade AES-256 bit encryption, support for multiple VPN protocols, powerful ability to unlock geographical restrictions, etc.

As for Chinese VPN users, PureVPN nodes are not specially optimized for the Chinese firewall, and the connection is slow and unstable after the firewall is updated.

Paid VPN software download 4: Surfshark download address

Surfshark is also a relatively new VPN brand. It has risen rapidly in the past two years and has gained high exposure. The advantage of Surfshark is that it allows unlimited devices to access the Internet at the same time, which is suitable for use with family or friends. So whether you want to save money, or your personal traffic needs for circumventing the firewall do not require a particularly large amount, or you want to buy it with friends or family, Surfshark will be your first choice.

Surfshark is also not available for download in China.

Paid VPN software download 5: CyberGhost download address

CyberGhost is a VPN that was very popular in China in the past. It is user-friendly, whether it is used for streaming, browsing, or P2P seed downloading. However, it is currently blocked, so it is not recommended for Chinese users to download CyberGhost VPN.

However, for users elsewhere, CyberGhost is reliable and excellent. Its powerful desktop apps for streaming and torrenting are impressive, especially for such an affordable price.

Paid VPN software download six: NordVPN download address

NordVPN was highly praised by netizens in the past, but unfortunately it is no longer available after the firewall update in 2021. After multiple tests, it still cannot connect in China, so it is not recommended for Chinese users to download NordVPN.

However, NordVPN still enjoys a certain reputation around the world due to its excellent security performance. If you are overseas and your main purpose is to use VPN to protect your online privacy, then NordVPN is a good choice.

Paid VPN software download seven: VyprVPN download address

VyprVPN is a Swiss-based company that is a high-quality, fast, and secure VPN that performed very well in the tests for this review. It offers many applications that are user-friendly, secure, and reliable. The unique Chameleon protocol is also well received in the industry, especially for iOS VPNs, which have good stability.

VyprVPN's server network is composed entirely of its own servers to eliminate all third-party factors and maintain high data security standards. However, like NordVPN, it has not been available since the 2021 firewall update.

Free VPN software download eight: QuickConnect VPN download address

If we only talk about the speed and stability of the Internet, I think LetsVPN is a good and scientific Internet access tool. Whether it is a computer or a mobile phone, whether it is an Android system or an I0S system, you can easily connect successfully in China.

For Chinese VPN users, it is not recommended to use it. There are big problems with security and privacy (local VPN in mainland China). If you use VPN on a daily basis, you need to pay more attention to your privacy and security. We recommend overseas VPN brands, such as PrivateVPN and ExpressVPN, which are much faster and more stable than Kuailian. > View Kuailian VPN Review <

Free VPN software download 9: Lantern VPN Download address

Lantern VPN was once an open source project. It is a VPN that uses V2ray technology and was very popular in China. If you just want to "taste" the experience of circumventing the firewall, Lantern VPN can meet your needs. If you often circumvent the firewall and have a lot of things to do after circumventing the firewall, we strongly recommend not to use Lantern VPN. There are more alternative circumvention tools for Lantern VPN. Any paid version of VPN is several times more stable and easy to use than Lantern.

Lantern VPN does not support refunds and has no customer service. Their packages are not short, which is a considerable expense. So don't buy packages easily. The important thing is that you spend money and still can't use it normally and safely. It is recommended that you choose carefully. > View Lantern VPN Review <

Free VPN software download 10: Laowang VPN download address

The reason why Laowang VPN is famous is not only because of its name, but also because it is a free VPN that can be used in China. Laowang VPN currently only supports Android systems and cannot be used on iOS and computers. For foreign users, if you need a VPN to change your IP, Laowang VPN may still work. > View Laowang VPN Review <

However, for users who want to bypass the firewall in China, Laowang VPN is not good enough as a VPN software, and Laowang VPN may also be a phishing VPN, so you must be careful. Check the confirmed VPN blacklist.

Free VPN software download 11: Ant VPN download address

AntVPN is a pretty standard free VPN, and it is unrealistic to expect it to be on par with the members in the paid VPN rankings. Therefore, it has basically the same problems as other free VPNs, that is, it is not stable enough, the speed is sometimes good and sometimes bad, the number of available nodes is small, and there is a bug that you can only start watching ads and earning points after you go over the firewall.

But it cannot be denied that it is indeed a free VPN. Although it is slow, it can still cope with the most basic needs of browsing popular websites, which is why its score is as high as 4.8. I recommend AntVPN to users who rarely use VPNs. If you use it for important social media such as Facebook or Twitter, or for important online activities, do not use AntVPN. After all, no one wants the VPN to fail at a critical moment. > View AntVPN Review <

Free VPN software download 12: ProtonVPN download address

ProtonVPN Free is a well-known free VPN overseas, which is not available in China yet. It has access to 3 VPN locations (located in the Netherlands, Japan, and the United States), can connect to 1 device, and has an intuitive and easy-to-understand interface.

Although the speed of the free version of ProtonVPN is average, its security features have not been castrated too much, so ProtonVPN is more suitable for people who need privacy protection rather than those who need to watch Netflix series. After upgrading to the premium version of ProtonVPN, you can get streaming and torrent download servers in more countries and regions, achieve faster speeds, add ad blocking and other features.

Related questions

Why is it so difficult to download a VPN in China?

Mainland China does not allow the spread of VPNs, and has blocked all VPN websites through its firewall. Major Android app stores such as Google have either blocked or removed apps from their shelves. Apple's App Store has also been ordered to delete VPN-related apps. Any public channels that allow us to access VPNs have been blocked.

Therefore, it is difficult for people without relevant knowledge to access VPN download methods, or even have never heard of VPN, because no one will take the initiative to tell you. Currently, people actively search for it and spread it through mirror websites and acquaintances.

Some VPNs do not provide download links on their official websites

Most of the VPNs that do not provide the function of downloading VPN installation packages are relatively well-known paid VPNs, such as ExpressVPN. Because they do not provide free trials, the trial can only be started after the subscription payment. You will get the download address of the installation package in the email after the payment is successful. Some other VPNs that can start free trials unconditionally can be downloaded and started directly without paying in advance, such as PrivateVPN for Android.

What to do if download speed is slow after using VPN?

This is for sure, because you are connecting to overseas through a VPN, and during this process, the VPN will encrypt your information and decrypt it, which takes time, so it will definitely be slower. So if you don't want to visit overseas websites, don't turn on the VPN.

What are the risks of downloading a free VPN?

Everyone loves free VPNs, but in fact, free VPNs may not be "cheap". VPNs are much cheaper now than in the past, and there are many special offers available. Free VPNs also have some other risks, such as: recording user information and causing privacy leaks; slow and unstable speeds; many ads, frequent disconnections; and may also come with harmful viruses.
