Starting from f44256c7dff6d24f1f940d4ca71219abbb0c7e34, pySim-shell now supports the non-standard files of the sysmoISIM-SJA2 SIM cards containing authentication key material for AKA and TS 03.48 OTA.
This way you can now interactively inspect and/or modify aspects such as
UMTS AKA key material and configuration¶
