I had this issue using the libre modem firmware on both phones. I’m not sure if it’s a modem side issue or a Linux side issue. I haven’t used either PinePhone with a SIM card in almost a year though so my knowledge could be outdated.
Thanks for clarifying. I also use the libre firmware and sometimes the modem doesn’t wake up from suspend when I unlock the phone (I sometimes also have to restart wifi with a script). So maybe I just didn’t notice the missed calls or something.
Lately I found that there is some USB controller and I saw some messages about it when running dmesg:
So maybe that causes the modem issues. When I use the keyboard addon, I can’t get any USB device to work when plugging it to the phone and I suspect that might be a connected problem too. I don’t know much about hardware, tough.
