We can read out the config memory, it's fun  |
OK, need to build a little debug loom first.

Becuase the SIM card may be restiricted to certain phone numbers, and also they might notice big phone bills to non Assist numbers

A Nokia 616 bluetooth car phone kit also has SAP plus a SIM slot, but it can't have a SIM and SAP active at the same time, since there is only one radio to connect to the network. The TCU might detect the SIM and disable SAP in a similar way. Still all to play for.
