I use the realme 7 pro on realme UI V1.0 and android 10, Build number RMX2170_11_A.34, Baseband version Q_V1_p14, kernel version 4.14.117, ColorOS V7. Using in Austria/Europe. Although both carriers (I use different ones with my two sim cards) support VoLTE and VoWIFI (it works well with Samsung S9+) I can't activate it on the realme because it is not even shown in the network settings. Is there anything I can do to make it work? I also tried changing the region of the device, but I always get invalid mmi code when entering *#3954391#. Also *#9434# does not work. I'm happy for any ideas, thank you!

I'm on version RMX2170_11_A.36. Using in Germany/Europe. My carrier is Drillisch (o2 network). Both buttons are availble in settings. Only thing I'm missing is the VoLTE symbol in statusbar. VoWiFi symbol is present in the specific situation.
when entering *#3954391#. Also *#9434# does not work.

What are these codes for? Any source for this? Thanks

I also have no VoLTE option available. I am on Realme UI 2.0, build RMX2170_11_C.26. Before Realme7Pro I had Xiaomi phone and VoLTE was working there fine without any issues, so it is definitely activated on the operator side. Just Realme phone doesn't give me any option to turn it on...Any ideas how to enable VoLTE here?

No, it seems that it would require the operator to activate VoLTE for our phone model and I didn't find any hidden menu where I could force enabling VoLTE.
I switched to Oneplus Nord 2, but I have the same problem - I have 2 SIMs from different operators, where one has VoLTE option visible and second doesn't (while it was visible in Xiaomi phone)...
