GRcard SIM

The GRcard SIM is a programmable GSM SIM card.

It uses a mixture of TS11.11 / ISO7816-4 and proprietary commands for programming

There is limited card programming support both in http://cgit.osmocom.org/cgit/pysim/ as well as the more interactive http://cgit.osmocom.org/cgit/cyberflex-shell/

Command reference

To understand this reference, it is assumed that you are familiar with basic knowledge on smartcard
technologies, such as standard ISO 7816-3/-4 APDUs and GSM TS 11.11.
