I have recently switched to iD from another pay monthly provider. Since then, I have been unable to receive phone calls in my house, despite having signal, and WiFi calling isn't working.
I have updated to the latest iOS, switched WiFi calling on, but despite having full wifi signal and being within 2 metres of the router, wifi calling isn't displaying on my phone. I have reset network settings, tried other wifi connections, and still not working.
I have an iPhone SE and am running on 12.3.1. Any advice would be appreciated.
