WiFi and 4G Calling with recent Huawei phones

[evantkh]

Has anyone tried to use WiFi or 4G Calling with any recent Huawei phones? If yes, does it require O2 firmware? or does Huawei provide carrier-branded firmware anyway?

There are no Huawei phones supported currently.

but it looks like Huawei is putting the carrier config of O2 UK in a firmware specifying the configuration of WiFi Calling and possibly VoLTE as well but it looks like Huawei is hiding the VoLTE switch. Does other O2 Android phones supporting VoLTE on O2 showing the VoLTE switch or it just works without a switch turning it on in the phone?

No you need the switch on the phone too.

The interesting thing is there is another carrier config file attempting to turn on EE's VoLTE by default but the model is not on EE's support list.

Must be planned then I guess?

and the device turns on VoLTE by default on another carrier in region I am currently located in uncerified(I mean not on the carrier's supported devices list here).
