Hi, I’m attempting to force operator selection using a BG600L module, but I keep encountering a USIM failure error. I’ve tried sending both of the following commands:
However, for both commands, I received error 13 (USIM failure). I also attempted to set CFUN to both 1 and 0, but there was no discernible difference. Even when I called AT+COPS=2 beforehand, it didn’t yield any positive results.
I’m sure the network is available because if I don’t intervene, the modem connects to it automatically. Therefore, I’m completely stumped. Do you have any insights into what might be causing this issue?
