Can't make or receive calls

Did phonecalls work when the phone was on Fairphone OS/Android?

Did phonecalls work when the phone was on Fairphone OS/Android?

I don't know because I installed Ubuntu Touch first thing I did.

I tried calling 112 and it worked actually, I got a tone. Just normal calls don't.

@ravachol
I suspect that there is something wrong with the apn settings. Do you have one apn for internet and one for sms?

[ravachol]

@Rondarius

My APN settings look like this:

3 (enabled)
Internet and MMS

3 SE MMS (disabled)
MMS

Both settings are the same however, and enabling the second one doesn't make a difference.

APN
data.tre.se

MMSC
https://mms.tre.se

Proxy
mmsproxy.tre.se

Proxy Port
7899

Username
Blank

Password
Blank

I can press + and there is a third setting for LTE there, but I enter data there and press the checkmark, but it is not added to the list.

@ravachol
Make the first one only internet
And reboot the phone.

[ravachol]

@Rondarius I've done that many times.

I also tried enabling ims by running:

sudo ./activate-context 3
sudo systemctl restart ofono

but ofono set's it back to disabled when it activates.

These are the settings:

[ /ril_0/context3 ]
Name = IMS
Active = 0
Preferred = 0
Type = ims
Protocol = dual
AccessPointName = ims
Username =
Passord =
AuthenticationMethod = any
Settings = { }
IPv6.Settings = { }

I think I need to change carrier or maybe swedish carriers aren't supported by ubuntu touch.

@Rondarius I didn't understand you at first. I did what you suggested and calls still don't work.

[Rondarius]

@ravachol
The sad thing is that it is a hit and miss with the carriers.
Tele2 had working calls, sms, mms on pixel 3a before VoLte. I had to figure out the right apn settings because the recommended settings just worked halfway.
Check if there exists other values for the apn settings.

[ravachol]

@Rondarius I managed to change the AccessPointName to ims.tre.se (data.tre.se gave an error)

Then set it to active. But when i run systemctl restart ofono it gets set to active = 0 again.

My guess is my carrier is rejecting the connection after which ofono disables it again. Or something like that.

@ravachol
Have you contacted Tre to see if the phone is blocked in some way?

[ravachol]

@Rondarius Yes, they were going to check and get back to me.

[ravachol]

@rondarius

Can you confirm that calling on Ubuntu Touch works with voLTE on Tele2 in Sweden? Because I might switch then, as the others are saying they don't know or that they can't. Comviq said they didn't know.

[ravachol]

Just to say I switched from Hallon (Tre) to Halebop, now everything works.
