I've not contacted O2 yet to try activate WiFi calling on my account, but have been reading many sites and posts that it won't work unless my phone has the correct O2 firmware on it. Can someone confirm if this is true and if so does anyone know where is best to get the correct firmware from and how to install it too? Thanks for any help you can give me Tue, 23 Mar 2021 07:58:41 GMT https://community.o2.co.uk/t5/Android/O2-firmware-for-Huawei-P20-pro/m-p/1449422#M77393 roccodeakin 2021-03-23T07:58:41Z https://community.o2.co.uk/t5/Android/O2-firmware-for-Huawei-P20-pro/m-p/1449429#M77394 <P><a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/4436203">@roccodeakin</a>&nbsp;</P><P>Try it first, but if you do need the O2 customisation, head over to XDA forums for help on that.</P> Tue, 23 Mar 2021 08:31:08 GMT https://community.o2.co.uk/t5/Android/O2-firmware-for-Huawei-P20-pro/m-p/1449429#M77394 MI5 2021-03-23T08:31:08Z https://community.o2.co.uk/t5/Android/O2-firmware-for-Huawei-P20-pro/m-p/1449462#M77395 Thanks MI5 I'll get in touch with them tomorrow and see what they say Tue, 23 Mar 2021 08:59:31 GMT https://community.o2.co.uk/t5/Android/O2-firmware-for-Huawei-P20-pro/m-p/1449462#M77395 roccodeakin 2021-03-23T08:59:31Z
