Hey,

> Thank you very much for the help. The customer added a few new logs after your answer and I'm putting the file here for the ones interested in this topic to see what is happening without the need to go to the Forum. There are a few error codes 100 after they activated the debug logs such as the following passages:
> ModemManager[260556]: <debug> [1656589406.833614] (ttyUSB1): <-- '<CR><LF>+CME ERROR: 100<CR><LF>'

None of those message have anything to do with the problem really.

Your debug log just shows the modem initialization phase, the modem
didn't get enabled and there is no connection attempt shown in the
logs. We need a full MM debug log that includes everything, including
connection attempts.
