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.

Thanks for your answer. Since my modem is already set to

Code:
+QMBNCFG: "List",9,1,1,"TF_Germany_VoLTE",0x05010C1B,201909201

indicated by the two "1"s, it seems I'll have to wait for the new modem driver and see, if this brings me VoLTE.
