Does anyone know if huaweip9 will work with WiFi calling, I have just bought one as it is in the list of compatible phones, it is arriving Monday.
BT Mobile does support Wi-Fi calling, I'd be lost without it, so according to the Huawei consumer website it should work Wifi calling P9 - HUAWEI Community
Unless it's changed recently, BT only officially support WiFi Calling on Android handsets supplied by them. It may well work anyway but you'll have no redress if it doesn't. If you dig around there's a very long thread about it, so someone there may be able to confirm. But I don't think it's been posted on for a year or so, so it may just be a case of suck it & see.
Ignore the list on the BT site, it hasn't been maintained in a long while now, the last advice I saw was some time back and that was to go by the list on the EE site.
My phone wasn't supplied by BT or EE, I got it from Argos and Wi Fi calling works a treat
