I am really new to this subject and just want to get MC7455 connected to
cellular network and getting an IP address but I haven't been able
I have tried several things without total success.Specially, when I use
qmicli I always get * service: CID allocation failed in the CTL client:
Transaction timed out*. No matter what options I try (I don't fully
understand what each of them does, just try to follow tutorials)

*ModemManager is not running*
