I have a Huawei Mate 20 Pro and know that the handset is capable of this but it's not listed as a compatible handset by O2. Why?</P> Thu, 06 Dec 2018 15:34:02 GMT https://community.o2.co.uk/t5/Pay-Monthly/VoWIFI/m-p/1177122#M161417 tim290480 2018-12-06T15:34:02Z https://community.o2.co.uk/t5/Pay-Monthly/VoWIFI/m-p/1177137#M161426 Mines working fine but as yours is a new device it will take some time to get it compatible with O2's services.
