Digital cellular telecommunications system (Phase 2+) (GSM); Subscriber Identity Modules (SIM); Functional characteristics (GSM 02.17 version 5.1.1 Release 1996)

Scope

The present document defines the functional characteristics and requirements of the Subscriber Identity Module (SIM) for use in GSM 900, GSM 1800 and PCS 1900 applications. All references to GSM shall apply equally to GSM 900, GSM 1800 and PCS 1900 unless otherwise stated. The SIM is the entity that contains the identity of the subscriber. When placed in a Mobile Equipment (ME), together they become a Mobile Station (MS) which may then register onto a GSM network. The primary function of the SIM in conjunction with a GSM network is to authenticate the validity of an MS when accessing the network. In addition it provides a means to authenticate the user and may also store other subscriber-related information or applications. Subscription entitlements are stored not in the SIM, but in the network.
