I had call drops on both the original and the Pro. They both use the same USB-attached modem and the modem has (had?) an issue where it would lose USB connection to the main processor sometimes, so you would just randomly lose cell connectivity. Sometimes the USB connection would restart right away and sometimes it would not and you’d have to restart eg25 manager to reboot the modem.
Ah, I see. It’s often hard to tell if some issue is still there if I don’t experience it myself. Some things get solved eventually, but you have to run the latest software (and I’m not) and then test things to see it. I think nowadays people recommend to install the libre modem firmware, so that’s also another variable.
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 I haven’t used either PinePhone with a SIM card in almost a year though so my knowledge could be outdated.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.
