sysmoUSIM-SJS1

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).

Please see shadysim.py for a tutorial on installing and removing a SIM Toolkit.

User Manual

sysmocom provides a user manual at https://www.sysmocom.de/downloads/sysmousim-manual.pdf

sysoUSIM-SJS1 is available from http://shop.sysmocom.de/ in both 2FF+3FF (micro) and 2FF+4FF (nano) form factors.
