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.

Setting the ICCID¶

Uses a standard UPDATE BINARY (D6) command on the EF.ICCID (2FE2)

Security: ADM2

Setting the IMSI¶

Uses a standard UPDATE BINARY (D6) command on the EF.IMSI (7F20/6F07)

Security: ADM2

Setting the Access Class¶

Uses a standard UPDATE BINARY (D6) command on the EF.ACC (7F20/6F78)

Security: ADM2

Setting the SMS Parameters¶

Uses a standard UPDATE RECORD (DC) command on the EF.SMS (7F10/6F42)

Security: ADM2

Setting the A3/A8 algorithm¶

Uses a standard UPDATE BINARY (D6) command on the non-standard (2700/6F70) EF

The record has a size of 1 byte and is defined as follows:

• 01 - COMP128v1
• 02 - COMP128v2
• 03 - COMP128v3

Security: ADM2
