I've been having trouble connecting my PinePhone (Manjaro) to my AT&T service (4G, Eastern US). A summary of my experiences (currently running Arch, but there was no real difference from Manjaro)...
Using mmcli's --simple-connect option (together with journalctl) shows that the connection almost works, but seems to get rejected eventually (I even see the 4G icon -- the phone is definitely aware of the network), usually with the QMI error "CallFailed".
I tried registering a new sim card in an online form with AT&T, but the web page reports something like "Device Not Found" when I enter my IMEI.
In talking to an AT&T tech for a little while, he suggested that he could manually enter the IMEI. While exploring this option, he noticed that AT&T seems to consider the Quectel Modem (model EG25-G, at least) to be an "internet only" (or "data only") device, that AT&T wouldn't support phone calls and SMS messages on it, and this might be the source of the problem. I didn't want to mess up my existing line, so we ended up not trying the manual IMEI registration.
Disappointing, but maybe informative. Has anyone had a similar experience?
