Pan Card Download Mobile Number Se

Your mobile phone number may be the key to your most important financial accounts. Text messages are often used by banks, businesses and payment services to verify your identity when you request updates to your account.

Mobile phone numbers can legally be ported from one provider to another when you switch your mobile phone service, and can also be ported from one mobile phone to another when you upgrade or change devices.

Scammers have been known to initiate porting requests. If they have enough of someone's personal information, they can attempt to con a victim's mobile phone company into believing the request is from the authorized account holder. If the scam is successful, the phone number will be ported to a different mobile device controlled by the scammer.

Another way to perpetrate this scam is to physically steal the victim's SIM card, a removable device in some mobile phones that carries a unique ID and stores the consumer's personal data. The scammer can then use the stolen SIM card in their own mobile device.

Every cell phone should have a unique factory-set electronic serial number (ESN) and a mobile identification number (MIN). A cloned cell phone is one that has been reprogrammed to transmit the ESN and MIN belonging to another cell phone. Scammers can steal ESN/MIN combinations by illegally monitoring the radio wave transmissions from the cell phones of legitimate subscribers. After cloning, both the legitimate and the fraudulent cell phones have the same ESN/MIN combination and cellular providers cannot distinguish the cloned cell phone from the legitimate one. Scammers can then run up expensive toll charges and the legitimate phone user gets billed for the cloned phone's calls. Alert your service provider if you see unauthorized calls or charges on your account.

I want to add the functionality of login similar to UPI apps. The user will select the SIM card from his phone and I will send an SMS from that SIM and will verify his phone number using that SMS. But I have to compare the number in the back-end or in API. So, I want to acquire the phone numbers of both SIM cards or the phone number of the SIM card user selects (Get the phone number from SMS or while sending SMS).

I am putting a generic class that I made for SIM selections and SMS. I have tried getting the mobile number from SubscriptionInfo, but it gives the operator name and all details right except the mobile number which returns an empty string. I have found in different blogs or my R&D that it is up to the operator whether to put the number there or not. So, if I am getting the mobile number, it is not 100% guaranteed that I will get the mobile number every time.

A SIM card (full form: Subscriber Identity Module or Subscriber Identification Module) is an integrated circuit (IC) intended to securely store an international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephone devices (such as mobile phones and laptops). Technically the actual physical card is known as a universal integrated circuit card (UICC); this smart card is usually made of PVC with embedded contacts and semiconductors, with the SIM as its primary component. In practice the term "SIM card" refers to the entire unit and not simply the IC.

A SIM contains a unique serial number, integrated circuit card identification (ICCID), international mobile subscriber identity (IMSI) number, security authentication and ciphering information, temporary information related to the local network, a list of the services the user has access to, and four passwords: a personal identification number (PIN) for ordinary use, and a personal unblocking key (PUK) for PIN unlocking as well as a second pair (called PIN2 and PUK2 respectively) which are used for managing fixed dialing number and some other functionality.[1][2] In Europe, the serial SIM number (SSN) is also sometimes accompanied by an international article number (IAN) or a European article number (EAN) required when registering online for the subscription of a prepaid card. It is also possible to store contact information on many SIM cards.

The first SIM cards were the size of credit and bank cards; sizes were reduced several times over the years, usually keeping electrical contacts the same, so that a larger card could be cut down to a smaller size.[4]

SIMs are transferable between different mobile devices by removing the card itself. eSIM is replacing physical SIM cards in some domains, including cellular telephony. eSIM uses a software-based SIM embedded into an unremovable eUICC.

The SIM card is a type of smart card,[3] the basis for which is the silicon integrated circuit (IC) chip.[5] The idea of incorporating a silicon IC chip onto a plastic card originates from the late 1960s.[5] Smart cards have since used MOS integrated circuit chips, along with MOS memory technologies such as flash memory and EEPROM (electrically EPROM).[6]

The SIM was initially specified by the ETSI in the specification with the number TS 11.11. This specification describes the physical and logical behaviour of the SIM. With the development of UMTS, the specification work was partially transferred to 3GPP. 3GPP is now responsible for the further development of applications like SIM (TS 51.011[7]) and USIM (TS 31.102[8]) and ETSI for the further development of the physical card UICC.

Today, SIM cards are ubiquitous, allowing over 7 billion devices to connect to cellular networks around the world. According to the International Card Manufacturers Association (ICMA), there were 5.4 billion SIM cards manufactured globally in 2016 creating over $6.5 billion in revenue for traditional SIM card vendors.[11] The rise of cellular IoT and 5G networks is predicted to drive the growth of the addressable market for SIM card manufacturers to over 20 billion cellular devices by 2020.[12] The introduction of embedded-SIM (eSIM) and remote SIM provisioning (RSP) from the GSMA[13] may disrupt the traditional SIM card ecosystem with the entrance of new players specializing in "digital" SIM card provisioning and other value-added services for mobile network operators.[6]

There are three operating voltages for SIM cards: 5 V, 3 V and 1.8 V (ISO/IEC 7816-3 classes A, B and C, respectively). The operating voltage of the majority of SIM cards launched before 1998 was 5 V. SIM cards produced subsequently are compatible with 3 V and 5 V. Modern cards support 5 V, 3 V and 1.8 V.[6]

Modern SIM cards allow applications to load when the SIM is in use by the subscriber. These applications communicate with the handset or a server using SIM Application Toolkit, which was initially specified by 3GPP in TS 11.14. (There is an identical ETSI specification with different numbering.) ETSI and 3GPP maintain the SIM specifications. The main specifications are: ETSI TS 102 223 (the toolkit for smart cards), ETSI TS 102 241 (API), ETSI TS 102 588 (application invocation), and ETSI TS 131 111 (toolkit for more SIM-likes). SIM toolkit applications were initially written in native code using proprietary APIs. To provide interoperability of the applications, ETSI chose Java Card.[14] A multi-company collaboration called GlobalPlatform defines some extensions on the cards, with additional APIs and features like more cryptographic security and RFID contactless use added.[15]

SIM cards store network-specific information used to authenticate and identify subscribers on the network. The most important of these are the ICCID, IMSI, authentication key (Ki), local area identity (LAI) and operator-specific emergency number. The SIM also stores other carrier-specific data such as the SMSC (Short Message service center) number, service provider name (SPN), service dialing numbers (SDN), advice-of-charge parameters and value-added service (VAS) applications. (Refer to GSM 11.11.[16])

SIM cards can come in various data capacities, from 8 KB to at least 256 KB.[10] All can store a maximum of 250 contacts on the SIM, but while the 32 KB has room for 33 Mobile country code (MCCs) or network identifiers, the 64 KB version has room for 80 MNCs.[17] This is used by network operators to store data on preferred networks, mostly used when the SIM is not in its home network but is roaming. The network operator that issued the SIM card can use this to have a phone connect to a preferred network that is more economic for the provider instead of having to pay the network operator that the phone discovered first. This does not mean that a phone containing this SIM card can connect to a maximum of only 33 or 80 networks, instead it means that the SIM card issuer can specify only up to that number of preferred networks. If a SIM is outside these preferred networks, it uses the first or best available network.[12]

Each SIM is internationally identified by its integrated circuit card identifier (ICCID). Nowadays ICCID numbers are also used to identify eSIM profiles, not only physical SIM cards. ICCIDs are stored in the SIM cards and are also engraved or printed on the SIM card body during a process called personalisation. 17dc91bb1f
