sysmoISIM
SIM/USIM/ISIM card that allows reprogramming of authentication information.
Standard-compliant GSM SIM + UMTS USIM + IMS/VoLTE ISIM card. It is intended for use in sysmoNITB / Osmocom-based cellular networks, but can also be used in any core network, including GSM (2G), UMTS (3G), LTE (4G), and even 5G. It supports cutting into three sizes of SIM cards: Classic SIM (2FF), Micro SIM (3FF), and Nano SIM (4FF). A key feature is the ability to reprogram (rewrite) authentication information (IMSI, K, OPC, etc.), allowing users to create and edit files and directories (EF or DF) within the card file system. Reprogramming requires the purchase of a card with ADM keys (with ADM keys / no ADM keys). SIM cards with ADM keys can also have Java applets installed.
