I live in an area with no mobile signal. I have recently turned on WiFi calling and can now make and receive mobile phone calls at home. I can send text messages. Unfortunately, I am not receiving text messages sent to me, and those that I know have been sent do not appear when I later enter an area where I get a Virgin Mobile signal.
My internet is provided by BT. I am using a 4G sim.
Is there a setting that I need to change?
