Re: Not receiving SMS or phone calls when wifi and lte are on.

Well here we are in 2019, and I'm experiencing this exact same problem with a new Xperia XA2.

I suspect the issue is related to the fact that my phone doesn't support VOWIFI (Voice-Over-WIFI) for my carrier (T-Mobile), but it expects VOWIFI to work. So it's turning off the LTE connection when it finds a persistent WIFI connection, because it should be able to use VOWIFI to receive voice calls and texts.
