From basic mobiles to high-end smartphones, cell phones keep the world connected. A lot has changed in the world of mobile devices in the last decade, so it's important to keep track of the latest technologies before making a purchase. With the extensive selection of cell phones available at Walmart, you can find the right phone for you no matter your needs and preferences.

Selecting a wireless carrier is one of the first decisions that you have to make when you want a new phone. In some cases, this can also determine the selection of phones you can choose from. You can opt for a contract or no-contract carrier, or go for a cell phone with a pre-paid plan. A contract carrier offers various monthly plans that can include minutes, texts, and data. You generally have to enter into a 12- or 24-month contract. No-carrier contracts allow you to get service from a smaller carrier such as a mobile virtual network operator without the yoke of a two-year contract. If you're looking for a specific phone but don't want to be tied to one carrier, you can purchase an unlocked version that can work on various carriers. Finally, pay-as-you-go or pre-paid plans are the most flexible option, as you can avoid surprises on your bill by topping up on an as-needed basis. Various bundles and data packs are available via pay-as-you-go options with most carriers.

Confirm the coverage: Large carriers such as Verizon or AT&T offer good coverage for high-speed Internet service across the country. You can confirm the coverage by using a zip code map provided by the carrier. Alternatively, ask your family or friends how well their phones work in a particular area.

Decide how much data you need: As not all providers offer the same deals for minutes, texts, and data, think about your regular usage before deciding on a carrier. If you spend more time texting and calling, then you only need a light data use plan. On the other hand, if you like to watch videos and download content on your phone, you may need a plan with 4GB or more. Some carriers also offer unlimited plans, so you'll never have to worry about your phone usage.

Most cell phones can handle at least a day's worth of phone calls, texts, and web browsing on a single charge. However, if you like to use your phone for music or gaming on a daily basis, you may need to consider getting a model with a longer battery life, which generally needs to be a 3,000 mAh battery or above. Heavy users may consider purchasing an external battery for their phone to avoid running out of juice at the end of the day.

With our wide range of cell phones, it's easy to find the exact features you want in your new handset. Once you have figured out what your new phone is going to be, have a look at some of our cell phone accessories such as cases, car mounts, and Bluetooth to get the most from your device, all at everyday low prices.

A mobile phone (or cellphone[a]) is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone (landline phone). The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and therefore mobile telephones are called cellphones (or "cell phones") in North America. In addition to telephony, digital mobile phones support a variety of other services, such as text messaging, multimedia messaging, email, Internet access (via LTE, 5G NR or Wi-Fi), short-range wireless communications (infrared, Bluetooth), satellite access (navigation, messaging connectivity), business applications, video games and digital photography. Mobile phones offering only basic capabilities are known as feature phones; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones.[1]

The first handheld mobile phone was demonstrated by Martin Cooper of Motorola in New York City on 3 April 1973, using a handset weighing c. 2 kilograms (4.4 lbs).[2] In 1979, Nippon Telegraph and Telephone (NTT) launched the world's first cellular network in Japan.[3] In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to over seven billion; enough to provide one for every person on Earth.[4] In the first quarter of 2016, the top smartphone developers worldwide were Samsung, Apple and Huawei; smartphone sales represented 78 percent of total mobile phone sales.[5] For feature phones (slang: "dumbphones") as of 2016[update], the top-selling brands were Samsung, Nokia and Alcatel.[6]

Mobile phones are considered an important human invention as it has been one of the most widely used and sold pieces of consumer technology.[7] The growth in popularity has been rapid in some places, for example in the UK the total number of mobile phones overtook the number of houses in 1999.[8] Today mobile phones are globally ubiquitous,[9] and in almost half the world's countries, over 90% of the population own at least one.[10]

A handheld mobile radio telephone service was envisioned in the early stages of radio engineering. In 1917, Finnish inventor Eric Tigerstedt filed a patent for a "pocket-size folding telephone with a very thin carbon microphone". Early predecessors of cellular phones included analog radio communications from ships and trains. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries. The advances in mobile telephony have been traced in successive "generations", starting with the early zeroth-generation (0G) services, such as Bell System's Mobile Telephone Service and its successor, the Improved Mobile Telephone Service. These 0G systems were not cellular, supported few simultaneous calls, and were very expensive.

The first handheld cellular mobile phone was demonstrated by John F. Mitchell[11][12] and Martin Cooper of Motorola in 1973, using a handset weighing 2 kilograms (4.4 lb).[2] The first commercial automated cellular network (1G) analog was launched in Japan by Nippon Telegraph and Telephone in 1979. This was followed in 1981 by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway, and Sweden.[13] Several other countries then followed in the early to mid-1980s. These first-generation (1G) systems could support far more simultaneous calls but still used analog cellular technology. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone.

In 1991, the second-generation (2G) digital cellular technology was launched in Finland by Radiolinja on the GSM standard. This sparked competition in the sector as the new operators challenged the incumbent 1G network operators. The GSM standard is a European initiative expressed at the CEPT ("Confrence Europenne des Postes et Telecommunications", European Postal and Telecommunications conference). The Franco-German R&D cooperation demonstrated the technical feasibility, and in 1987 a Memorandum of Understanding was signed between 13 European countries who agreed to launch a commercial service by 1991. The first version of the GSM (=2G) standard had 6,000 pages. The IEEE and RSE awarded to Thomas Haug and Philippe Dupuis the 2018 James Clerk Maxwell medal for their contributions to the first digital mobile telephone standard.[14] In 2018, the GSM was used by over 5 billion people in over 220 countries. The GSM (2G) has evolved into 3G, 4G and 5G. The standardisation body for GSM started at the CEPT Working Group GSM (Group Special Mobile) in 1982 under the umbrella of CEPT. In 1988, ETSI was established and all CEPT standardization activities were transferred to ETSI. Working Group GSM became Technical Committee GSM. In 1991, it became Technical Committee SMG (Special Mobile Group) when ETSI tasked the committee with UMTS (3G).

Smartphones have a number of distinguishing features. The International Telecommunication Union measures those with Internet connection, which it calls Active Mobile-Broadband subscriptions (which includes tablets, etc.). In the developed world, smartphones have now overtaken the usage of earlier mobile systems. However, in the developing world, they account for around 50% of mobile telephony.

Feature phone is a term typically used as a retronym to describe mobile phones which are limited in capabilities in contrast to a modern smartphone. Feature phones typically provide voice calling and text messaging functionality, in addition to basic multimedia and Internet capabilities, and other services offered by the user's wireless service provider. A feature phone has additional functions over and above a basic mobile phone, which is only capable of voice calling and text messaging.[18][19] Feature phones and basic mobile phones tend to use a proprietary, custom-designed software and user interface. By contrast, smartphones generally use a mobile operating system that often shares common traits across devices.

The critical advantage that modern cellular networks have over predecessor systems is the concept of frequency reuse allowing many simultaneous telephone conversations in a given service area. This allows efficient use of the limited radio spectrum allocated to mobile services, and lets thousands of subscribers converse at the same time within a given geographic area.

A cellular network mobile phone system gets its name from dividing the service area into many small cells, each with a base station with (for example) a useful range on the order of a kilometre (mile). These systems have dozens or hundreds of possible channels allocated to them. When a subscriber is using a given channel for a telephone connection, that frequency is unavailable for other customers in the local cell and in the adjacent cells. However, cells further away can re-use that channel without interference as the subscriber's handset is too far away to be detected. The transmitter power of each base station is coordinated to efficiently service its own cell, but not to interfere with the cells further away. 2351a5e196
