No. Unfortunately not.
The mobile networks that shows up are Virgin, O2, Three, EE, etc... Options range from G all the way up to 4G.
I do not have VoLTE and Wifi Calling, but I actually never managed to get them working before with other carriers. The options under Call Settings don't even show up.
I have a feeling it is something that needs to be switched on from Virgin Mobile, but of course it could be a problem with Google Mobiles also.
5G is listed as my preferred network type.
5G should be available in my location, but I cycled to Hammersmith yesterday just to double check 2 different locations.
Thanks for the quick answer buddy.
