This means the authentication data stored in the network does not correspond to what is stored in the USIM. This can come from incorrect Ki or SQN values in the AuC.db file, or an incorrect AuC.OP value in the corenet.py file.

You should probably reprogram your USIM to resynchronize those 3 parameters correctly with your network config.
