VoLTE calls with o2 (Germany)
02-03-2021, 08:35 AM
This are maybe some good news to you. For me VoLTE on German Telefonica network is so far working well and I got an superior call audio quality.
I'm using pmOS edge on a Ubports CE with a Simplytel sim card by Drillisch. Reception indoors is sometimes problematic but otherwise fine.
As far as I know pmOS is using some AT Commands to select a custom VoLTE profile and sets my APN setting for mobile data automatically.
Their wiki gives you more information about how they are doing it and there is even a request to enable it in Mobian in the near future.
If I were you, I would try to follow their instructions and put them in startup script that is executed on boot. See the Mobian =rc]wiki for a way to do so.
Since I also got only 2G calls while I was using MedionMobile, it is possible that some cheaper providers are not able to do VoLTE on Telefonica Network.
From your post I understand that you are using a O2 plan and should get VoLTE. If above steps are working, please report back on the Mobian to get this merged more quickly.
