SIM (Subscriber Identity Module) – If you have a cellular device that requires GSM, GPRS, or EDGE services, then you will also require a SIM card. As the name implies, this is a media storage device (available from the service provider) that identifies your cellular device to the network, in addition to storing personal information, such as the user’s contact list. A SIM card is about the size of a postage stamp. If you have a cellular device that functions despite not having a SIM card installed, then that device is likely a CDMA-enabled device.
