the fundamentals of how the modem talks to the carrier should belong to the GSM protocol
Thanks for the info.

When you say it happens to you with other phones, do you mean calling other phones from the PinePhone?
Is that a problem on the PinePhone side?
For me it's just with incoming calls, outgoing works fine even when incoming stops working.

I upgraded my mainboard to 1.2b 3GB

if there is a new stable firmware you should see it in dmesg
I tried latest arch and manjaro phosh, problem is still there.
I also tried an older arch phosh image, which also had the problem. I definitely didn't have this problem before, I would have noticed it while testing my scripts, which makes me believe that it's likely a firmware bug, although I didn't find any firmware warnings on dmesg.
(I kept ModemManager and all the magic background stuff running, but I think we can agree that's not the problem, so it would be pointless to try again without it)

I really don't think I'm missing any AT command, the problem still occurs if the only AT command I type is to unlock the SIM, then I just call it, it rings, I hangup from the phone that's calling, I call again and it doesn't ring this time.
