h1. pySim WiKi 

pySim-prog is a small command line utility written in python, which is used for programming various programmable SIM/USIM cards.

Such SIM/USIM cards are special cards, which - unlike those issued by regular commercial operators - come with the kind of keys that allow you to write the files/fields that normally only an operator can program.

This is useful particularly if you are running your own cellular network, and want to issue your own SIM/USIM cards for that network.

h2. Supported Cards

* [[cellular-infrastructure:sysmoUSIM-SJS1]]

* [[cellular-infrastructure:GrcardSIM]]

* [[cellular-infrastructure:GrcardSIM2]]

* [[cellular-infrastructure:MagicSIM]]

h3. Example of how to program a sysmoSIM-GR1 card 

The GRcard SIM is a programmable GSM SIM card. It uses a mixture of TS11.11 / ISO7816-4 and proprietary commands for programming.

In the below example, we are changing the card’s IMSI to 901700000003080 (option -i) and we are specifying a new set of -n NAME (Operator name), -t TYPE (Card type), -c CC (Country code), -x MCC (Mobile Country Code), -y MNC (Mobile Network Code) and -s ID (Integrated Circuit Card ID) values.

 $ ./pySim-prog.py -p 0 -n OpenBSC -t sysmosim-gr1 -i 901700000003080 -c 001 -x 001 -y 02 -s 1791198229180000075

h3. Example of how to program a sysmoUSIM-SJS1 card

(U)SIM cards are Java capable and there is the Globalplatform that specifies standards API. SMS can be addressed directly to the SIM card, the SIM card will get events for network selection and others, it can modify call establishment attempts.

Provisioning of different identities or keys.

If you have a variant of the card-individual ADM1 key of your sysmoUSIM-SJS1 card,  you can change any identity (IMSI, ICCID, MSISDN) stored on the (U)SIM, as well as the private key data (K, OPC).

In the below example, we are changing the card’s IMSI to 901700000003080 (option -i) and we are specifying a new set of -t TYPE (Card type), - a ADM_PIN (ADM PIN used for provisioning), -x MCC (Mobile Country Code), -y MNC (Mobile Network Code), -s ID (Integrated Circuit Card ID), -o OPC and -k KI (Ki) values.

 $ ./pySim-prog.py -p 0 -t sysmoUSIM-SJS1 -a 58001006  -x 901 -y 71 -i 901700000010659 -s 8988211000000110000 -o 398153093661279FB1FC74BE07059FEF -k 1D8B2562B992549F20D0F42113EAA6FA

 Insert card now (or CTRL-C to cancel)

 Generated card parameters :

  > Name    : Magic

  > SMSP    : e1ffffffffffffffffffffffff0581005155f5ffffffffffff000000

  > ICCID   : 8988211000000110000

  > MCC/MNC : 901/71

  > IMSI    : 901700000010659

  > Ki      : 1D8B2562B992549F20D0F42113EAA6FA

  > OPC     : 398153093661279FB1FC74BE07059FEF

h3. Example of how to program a Magic SIM / SuperSIM 16-in-1 / X-sim card

The 16-in-1 SIM cards are intended for COMP128v1 based cloning and enable the user to aggregate up to 16 SIM card identities in a single card. This multi-IMSI property is not used in the context of Osmocom.

Below example shows how we can change the card’s IMSI to 901990000000018 (option -i) and at the same time we are specifying a new set of -x MCC (Mobile Country Code), -y MNC (Mobile Network Code), -s ID (Integrated Circuit Card ID) , -o OPC and -k KI (Ki) values.

 $ ./pySim-prog.py -p 0 -x 801 -y 71 -i 901990000000018 -s 8988211000000110000 -o 398153093661279FB1FC74BE07059FEF -k 1D8B2562B992549F20D0F42113EAA6FA

 Insert card now (or CTRL-C to cancel)
