CLEARLY the problem is xfinity mobile has OS set to prioritize using mobile network. At my house we have a weak one bar so calls don’t work over mobile network but it’s just enough signal that the phone won’t use Wi-Fi. It won’t even receive a call. Other carriers have figured out that the priority has to be the other way around. If they don’t fix it I have to flip back to Att.
