SIM card is the abbreviation of (subscriber identity module).

GSM digital mobile phones are also called subscriber identification cards and smart cards, and they must be installed before they can be used. Digital mobile phone customer information, encryption key and user phone book are stored on the computer chip, which can be used to authenticate the identity of GSM network customers and encrypt the voice information when customers talk.

SIM card is a chip card with a microprocessor. It has five modules, each corresponding to a function: microprocessor CPU(8 bits), program memory ROM(3~8kbit), working memory RAM(6~ 16kbit), data memory EEPROM( 128~256kbit) and serial communication unit. These five modules are encapsulated in the copper interface of SIM card like ordinary IC cards. These five modules must be integrated into an integrated circuit, otherwise their security will be threatened, because the connection between chips may become an important clue for illegal access and theft of SIM cards.
