h1. 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 https://git.osmocom.org/pysim/ http://cgit.osmocom.org/cgit/pysim/ as well as the more interactive https://git.osmocom.org/cyberflex-shell/. http://cgit.osmocom.org/cgit/cyberflex-shell/
h2. 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.
h3. Setting the ICCID
Uses a standard UPDATE BINARY (D6) command on the EF.ICCID (2FE2)
Security: ADM2
h3. Setting the IMSI
Uses a standard UPDATE BINARY (D6) command on the EF.IMSI (7F20/6F07)
Security: ADM2
h3. Setting the Access Class
Uses a standard UPDATE BINARY (D6) command on the EF.ACC (7F20/6F78)
Security: ADM2
h3. Setting the SMS Parameters
Uses a standard UPDATE RECORD (DC) command on the EF.SMS (7F10/6F42)
Security: ADM2
h3. 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
h3. Setting the Ki
Uses a non-standard APDU @80 D4 02 00 10@, followed by 16 bytes of Ki
Security: none
h3. 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
h3. 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
h3. 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
h3. 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
h3. 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
h3. Erase Card
Uses a non-standard APDU @80FE000014 31323334353600001301FF0000000000000000EA@
Security: none
h3. Authenticate as ADM0
Uses a non-standard APDU @80 F6 00 00 08 PIN@, where per default PIN is @0000000000000000@
