Does anyone answer or even solve this problems on this BT forum?
Sometimes, although it's rather dependent on knowing what the problem is.
very much like the post above, i have a nokia 7 plus but on the bt app it says 4g & wifi calling not supported but it is available on that phone. i have android version 9 which is above the 7 required
Thanks for posting back!
You can use this link to see a list of compatible devices
I have had a quick scan of the list and it doesn't look like the Nokia 7 Plus is compatible I'm afraid. There is also a section below on the link that explains how you can check if a handset is compatible.
Note: In order to use WiFi Calling, please make sure your Nokia 7 Plus is updated to Android 7.0 (Nougat).
mine is on version 9
there is nothing that says you cannot use wifi calling if your phone has it just your specific phone is not supported by BT for wifi calling - or have you phone somewhere where BT actually say your phone is supported?
There is a lack of BT support for Nokia phones, even though they supply them. The offical silence on this is deliberate, I believe.
