SIM cards can also be used in satellite phones, computers, or cameras.
The SIM circuit is part of the function of a universal integrated circuit card (UICC) physical smart card, which is usually made of PVC with embedded contacts and semiconductors.
ICCIDs are stored in the SIM cards and are also engraved or printed on the SIM card body during a process called personalisation.
This specification describes the physical and logical behaviour of the SIM.
With the development of UMTS the specification work was partially transferred to 3GPP.
A SIM card contains its unique serial number (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 two passwords: a personal identification number (PIN) for ordinary use, and a personal unblocking code (PUC) for PIN unlocking.
The SIM was initially specified by the European Telecommunications Standards Institute in the specification with the number TS 11.11.
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 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.As mentioned in the above video, there are a number of improvements, adjustments, and fixes that I strongly desire to implement, so a new build will probably drop within the next few days, although you shouldn’t expect it to contain a huge new feature.As for the release date of the game’s next big feature…I’d love to say May 15th, but it’s entirely possible that it might take until June 1st to implement.To provide interoperability of the applications, ETSI chose Java Card..Additional standard size and specifications of interest are maintained by Global Platform."SIM cards" are transferable between different mobile devices.
