I've just got a Motorola g 5G plus phone which is capable of, and offers me the option of making calls over WiFi on my BT SIM. When I set it to do this, it will not make or receive calls - they apparently connect (in and outbound) and then cut off immediately. Is there a way to use this facility on my SIM only BT account?
did you get the new phone from BT?
Did you just turn it on in the phone or did you have to do anything else on your phone or in your BT account, say?
I just turned it on the phone and it worked ever since. The app funnily enough tells me that 4g and WiFi calling are not available (when they are)
Partially. I have used it since and it works fine on outbound calls to another mobile. As far as I know, it works inbound mobile to mobile. The problem may well be confined to calls outbound from the mobile to a BT landline but I haven't tested it extensively.
