PinePhone can't make outbound calls

[dukla2000]

I am new on this forum and new to the pine phone and I hope I can learn a lot
...

Welcome, and hopefully you enjoy the journey.

...
I am hoping that posting here will give me some hints but maybe what I am really asking for is where I can find error logs for such thing
...

Try opening a terminal window and typing the command

Code:

journalctl -f

which will show the last few lines of the system journal and will carry on running and show any new entries as they are added.

Then again I have no idea if Ubuntu Touch is systemd based: in any event I would recommend you flash the latest version of Mobian onto an SDcard and try that. I do it every couple of weeks and it just works for me: the point of this suggestion is to check you don't have some weird phone/SIM/provider glitch. (Or you could try Arch - again I flash it every couple of weeks and calls just work. Both Mobian & Arch are phosh based, unlike UT IIRC. UT uses ofono for plain old telephony and that may be troublesome in your environment.)
