Product Description:
SIM card is One consistent with GSM specifications "smart card", It is actually a chip card that contains the microprocessor, internal five modules, and each module corresponds to a function: CPU (8-bit), the program memory ROMR (3 ~ 8 kb), working memory RAM (6 ~ 16 kb), data memory EEPROM (128 ~ 256 kb) and serial communication unit. SIM card can achieve storage data (phone book, SMS, etc.) and in safe conditions (personal identification number PIN, the authentication key Ki correct) completion of customer identity authentication and encryption algorithms customer information process. These functions are microprocessor having aSIM card from the operating system is complete.
SIM card by the integrated circuit module and the plastic card body mass composition, in line with ISO7816 series of standards
SIM card chip embedded in the circuit board top, and then packaged into the card body inside
