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

Setting the Ki

Uses a non-standard APDU 80 D4 02 00 10, followed by 16 bytes of Ki

Security: none

Setting the PIN1 and PUK1

Uses a non-standard APDU 80 D4 00 01 10 followed by 8 bytes of PIN1 and 8 bytes of PUK1

Security: none

Setting the PIN2 and PUK2

Uses a non-standard APDU 80 D4 00 02 10 followed by 8 bytes of PIN2 and 8 bytes of PUK2

Security: none

Setting the ADM1 + AUK1

Uses a non-standard APDU 80 D4 01 04 12 03 00 followed by 8 bytes of ADM1 and 8 bytes of AUK1

Security: none

Setting the ADM2 + AUK2

Uses a non-standard APDU 80 D4 01 05 12 03 00 followed by 8 bytes of ADM2 and 8 bytes of AUK2

Security: none

Create File

Uses a non-standard APDU 80 CF 00 P2 LEN FID SIZE OPT1 ACC OPT2, specified as follows:

  • Parameter P2:
    • 00: Create DF
    • 01: Create linear record EF
    • 02: Create transparent EF
    • 03: Create cyclic record EF
    • 04: used to create EF.0001 with size {{{0A20}}}
  • FID: The 2 byte File ID
  • SIZE: 2 bytes for the transparent EF size; or 1 byte for the number of records, and 1 byte for the record size for linear or cyclic EF
  • OPT: Always 0100
  • ACC: Access conditions (3 bytes), According to TS 11.11, Section 9.3
  • OPT2: Always FF

Security: ADM0

Erase Card

Uses a non-standard APDU 80FE000014 31323334353600001301FF0000000000000000EA

Security: none

Authenticate as ADM0

Uses a non-standard APDU 80 F6 00 00 08 PIN, where per default PIN is 0000000000000000
