No idea I'm afraid.
All I've ever done is put the SIM in, and it's configured to what you see.
Did have to login to Audi Connect again recently - but that can't affect the APN and username settings that it gets from the SIM.
You do have a pre-loaded X months/X Gb data SIM? Not a normal PAYG or contract one?
My two cards have been the pre-loaded Data SIM ones.
