What type of cards, consisting of a microprocessor and internal memory, are usually found in GSM devices?

In GSM networks, service access hinges on a SIM card, which is a small card that contains a microprocessor and memory to store the subscriber’s identity and cryptographic keys. The SIM holds the IMSI (the subscriber’s unique identifier) and authentication keys, and it runs the cryptographic processes needed to authenticate the device to the mobile network and authorize service. This enables roaming, billing, and secure access to network resources. Other options—SD cards, NFC tags, or USB flash drives—are mainly storage or tagging devices and do not carry the network authentication data or perform the mobile network’s cryptographic checks, so they don’t play the same role in GSM devices. Modern devices may use an embedded SIM (eSIM), but its fundamental function remains to provide identity and secure access to the cellular network.
