This repository contains a python language utility to configure the vendor-specific parameters of sysmoUSIM-SJS1 programmable USIM cards.

For more information about the sysmoUSIM-SJS1, please see the related user manual


The sysmoUSIM-SJS1 is programmable and Java capable USIM card. Not all commands are known yet and this page should grow over time. Each card is using a separate ADM1 key and the default configuration is hacker/developer friendly (fields being writable, reduced security for installing applets to have more quick development cycles).

The cards are available from the sysmocom webshop


On Debian:

apt-get install python-pyscard pcscd systemctl start pcscd
