[[PageOutline]] 
 = 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 RECORD (DC) 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 
  * OPT1: Always {{{0100}}} 
  * ACC: Access conditions (3 bytes), According to TS 11.11, Section 9.3  
  * OPT2: Always {{{FF}}} 

 In case a Directory or EF.0001 is created, OPT1, ACC and OPT2 are replaced with 8-bytes all-zero {{{00000000000000}}} 

 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}}}
