Telephony stopped working

I can still send and receive SMSs.
This is a Pinephone 3/32 running Linux mobian 5.15-sunxi64 #1 SMP Tue Feb 15 08:08:10 UTC 2022 aarch64 GNU/Linux
I am assuming there is probably a file that got loaded with junk but a restart, even running updates has not re-enabled phone calls.
I cannot
-dial number from dialpad screen
-dial numbaers from call log
-receive/answer calls and no incoming/missed calls appear in call log

GPS works, SMS works

I have never gotten my 3g/4g data to ever connect.
I have been using this installation to follow Mobian for several months with another SIM installed and rarely made and received successful telephone calls; but first began using Pinephone as my primary two days ago and the error occurred after 3-4 hours of use where the calls were received and rang the ringtone both when awake and in sleep/standby mode..

What carrier are you with? Is it 4G VoLTE only or does it switch to 3G for calls?

Lots of threads on various telcos, use the search.
Here are some commands you can use to interrogate the modem
(if IMS VoLTE applies you need to find the profile that works, if it exists)

If your operator does not support IMS / VoLTE you could try disabling IMS in /usr/share/eg25-manager/ config file by setting
{ cmd = "QCFG", subcmd = "ims", value = "2" }
comment out the expect = 1 line (or modify it)
then restart eg25-manager:
sudo systemctl restart eg25-manager (I think) or reboot

You can also look at logs
sudo journalctl -b | grep modem
sudo journalctl -b | grep modemmanager
sudo journalctl -b | grep eg25-manager

A lot of people seem to have problems in the US with the modem eventually being blacklisted and kicked off the network, could happen elsewhere too, perhaps?

Note if you use /etc/eg25-manager/ directory for changes to be persistent you need to check the file in /usr/share/eg25-manager hasn't changed after an update as that can result in the modem just not working.

Good luck, let us know what you find out!

Consider adding the operator and country in the title as other users could help.
Pinephone v1.2 UBports CE. Adelaide, Australia using Amaysim SIM (Optus network, non-VoLTE) with Mobian SD card.
Manjaro Plasma Mobile on EMMC.
