What is a SIM card?

Find out what SIM stands for and its uses.

By Joao Lima

A SIM card, or in its full form, subscriber identity module, is an integrated circuit chip car that is used to receive, store and retrieve GSM data from the global system for mobile communication (GSM) subscribers.

The SIM card was first specified by the European Telecommunications Standards Institute under TS 11.11.

With the appearance of the universal mobile telecommunications system (UMTS) built by the 3GPP, the SIM card specification was transferred to the 3GPP.
