I have a Samsung A50 and have turned on WiFi calling but BT shows not available. Do I need to change any settings?
I don't see WiFi calling on screen.
Both MyBT and the app show WiFi calling not availabe, same with 4g calling.
I didn't buy it from BT
The app is only a guide based upon whether BT officially support a particular phone or not, not whether it will work or not.
The main problem is that because the phone wasn't supplied by BT, it's unlikely to have the correct firmware.
This very lengthy thread is worth having a look at, try jumping in around Page 70 at a rough guess. You could try changing the firmware but that has risks.
