The file EF.AD contains the length of the MNC, this allows to phone to distinguish where MCC/MNC end and where the MSIN number of the IMSI begins. All cards are shipped with an MNC length of 2, which is fine for the most situations, but when a MNC with 3 digits is needed the MNC length value has to be updated. Otherwise the phone will recognize the third digit of the MNC as part of the MSIN. Related: OS#3850

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
