Subscriber Identity Module
A typical SIM card (mini-SIM with micro-SIM cutout)A SIM card or SIM (subscriber identity 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, tablets, and laptops). SIMs are also able to store address book contacts information, and may be protected using a PIN code to prevent unauthorized use. SIMs are always used on GSM phones; for CDMA phones, they are needed only for LTE-capable handsets. SIM cards are also used in various satellite phones, smart watches, computers, or cameras. 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, to fit smaller-sized devices. SIMs are transferable between different mobile devices by removing the card itself. Technically, the actual physic ...

VMAC
VMAC is a block cipher-based message authentication code (MAC) algorithm using a universal hash proposed by Ted Krovetz and Wei Dai Wei Dai ( zh, c=戴维 or zh, c=戴伟) is a computer engineer known for contributions to cryptography and cryptocurrencies. He developed the Crypto++ cryptographic library, created the b-money cryptocurrency system, and co-proposed the VMAC ... in April 2007. The algorithm was designed for high performance backed by a formal analysis. VMAC is designed to have exceptional performance in software on 64-bit CPU architectures while still performing well on 32-bit architectures. Measured speeds are as fast as one-half CPU cycle per byte (cpb) on 64-bit architectures, under five cpb on desktop 32-bit processors, and around ten cpb on embedded 32-bit architectures. A closely related variant of VMAC that is optimized for 32-bit architectures is given by UMAC. Overview VMAC is a MAC in the style of Wegman and Carter. A fast "universal" hash functi ...

MEID
A mobile equipment identifier (MEID) is a globally unique number identifying a physical piece of CDMA2000 mobile station equipment. The number format is defined by th3GPP2 report S.R0048but in practical terms, it can be seen as an International Mobile Equipment Identity, IMEI but with hexadecimal digits. An MEID is 56 bits long (14 hexadecimal digits). It consists of three fields, including an 8-bit regional code (RR), a 24-bit manufacturer code, and a 24-bit manufacturer-assigned serial number. The check digit (CD) is not considered part of the MEID. The MEID was created to replace electronic serial numbers (ESNs), whose virgin form was exhausted in November 2008. As of TIA/EIA/IS-41 Revision D and TIA/EIA/IS-2000 Rev C, the ESN is still a required field in many messages—for compatibility, devices with an MEID can use a pseudo-ESN (pESN), which is a manufacturer code of 0x80 (formerly reserved) followed by the least significant 24 bits of the SHA-1 hash of the MEID. MEIDs ar ...

Smart Card
A smart card (SC), chip card, or integrated circuit card (ICC or IC card), is a card used to control access to a resource. It is typically a plastic credit card-sized card with an Embedded system, embedded integrated circuit (IC) chip. Many smart cards include a pattern of metal contacts to electrically connect to the internal chip. Others are Contactless smart card, contactless, and some are both. Smart cards can provide personal identification, authentication, data storage, and application processing. Applications include identification, financial, public transit, computer security, schools, and healthcare. Smart cards may provide strong security authentication for single sign-on (SSO) within organizations. Numerous nations have deployed smart cards throughout their populations. The universal integrated circuit card (UICC) for mobile phones, installed as pluggable SIM card or embedded eSIM, is also a type of smart card. , 10.5billion smart card IC chips are manufactured annually ...

W-SIM
W-SIM(RX420AL) W-SIM (Willcom-SIM) is a SIM card developed by Willcom which, in addition to standard SIM functions, also has the core components of a cellular telephone ( PHS), such as the radio receiver/transmitter, built inside. It is currently used in some terminals (listed below), which do not have radio modules. The W-SIM core module is an extended version of a SIM card, containing not only user data but also all the transmission technology needed for a mobile device to work. A terminal device developer can build a customized terminal without the design and development of a radio module, and users can change to a different radio module W-SIM without changing the terminal itself. Similar to traditional handsets made by WILLCOM, W-SIM terminals can be used in Japan, including global roaming with Taiwan and Thailand. For Mainland China, China Netcom had W-SIMs available, though its PHS network is due to be phased out this year. In addition, a GSM version called the CM ...

R-UIM
Removable User Identity Module (R-UIM, usually pronounced as "R-yuim") is a card developed for cdmaOne/CDMA2000 ("CDMA") handsets that extends the GSM SIM card to CDMA phones and networks. To work in CDMA networks, the R-UIM contains an early version of the CSIM application. The card also contains SIM (GSM) application, so it can work on both networks. It is physically compatible with GSM SIMs and can fit into existing GSM phones as it is an extension of the GSM 11.11 standard. This interface brings one of the main advantages of GSM to CDMA network phones. By having a removable identity card, CDMA users can change phones while keeping their phone numbers by simply swapping the cards. This simplifies many situations such as phone upgrades, phone replacements due to damage, or using the same phone on a different provider's CDMA network. The R-UIM card has been superseded by CSIM on UICC. This technique allows all three applications (SIM, CSIM, and USIM) to coexist on a si ...

IP Multimedia Services Identity Module
An IP Multimedia Services Identity Module (ISIM) is an application residing on the Universal integrated circuit card, UICC, an Integrated circuit, IC card specified in TS 31.101. This module could be on a UMTS 3G or IP Multimedia Subsystem, IMS LTE (telecommunication), VoLTE network. It contains parameters for identifying and authenticating the user to the IMS. The ISIM application can co-exist with Subscriber Identity Module, SIM and Universal Subscriber Identity Module, USIM on the same UICC making it possible to use the same smartcard in both Global System for Mobile Communications, GSM networks and earlier releases of Universal Mobile Telecommunications System, UMTS. Among the data present on ISIM are an IP Multimedia Private Identity (IMPI), the home operator domain name, one or more IP Multimedia Public Identity (IMPU) and a long-term secret used to authenticate and calculate cipher keys. The first IMPU stored in the ISIM is used in emergency registration requests. External l ...

Dual SIM
Some mobile phones support use of two SIM cards, described as dual SIM operation. When a second SIM card is installed, the phone may allow users to switch between two separate mobile network services manually, have hardware support for keeping both connections in a "standby" state for automatic switching, or have two transceivers to maintain both network connections at once. Dual SIM phones are mainstream in many countries where phones are normally sold unlocked. Dual SIMs are popular for separating personal and business calls, in locations where lower prices apply to calls between clients of the same provider, where a single network may lack comprehensive coverage, and for travel across national and regional borders. In countries where dual SIM phones are the norm, people who require only one SIM leave the second SIM slot empty. Dual SIM phones usually have two unique IMEI numbers, one for each SIM slot. Devices that use more than two SIM cards have also been developed and relea ...
