History of SIM

The SIM card was introduced in 1991 in order to support GSM service in various European countries. The SIM is a relatively small, inexpensive memory chip with a security algorithm that provides a protection mechanism against malicious manipulation. The SIM card allows identification and authentication effectively utilizing EAL-5 (Evaluation Assurance Level).

ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) created the standards for smart cards together, and serve as the base for most smart card standards. Another standard organization, ETSI (European Telecommunication Standards Institute), has also created smart card standards in the Technical Committee for Smart Card Platform (TC SCP). The TS 51.011 family of standards specifies the interface between the smart card (SIM) and the mobile device [1].
