Just bought a P20 Pro last week and it's great. I wondered about WiFi calling using O2 as I live in a slight dip with the signal occasionally dropping. I looked on O2's website and none of Huawei's phones are listed as being on O2's list of phones with WiFi calling. I knew that although network dependant, the P20 Pro has the ability for WiFi calling so I Googled for more info and it strangely provided a link to O2's own pages on how to turn it on though the options on the final screenshots in their instructions don't appear on my phone. O2 weren't much help but does anyone know if this will happen soon. I'd have thought that if O2 themselves have model-specific instructions on their website that it means it's on its way. Help!
