Xfinity Mobile WiFi calling not functioning on Samsung Galaxy S20 Ultra
I've noticed numerous posts regarding Xfinity Mobile WiFi Calling not functioning (or functioning sporadically) on a variety of iPhones. However, I have a new Samsung Galaxy S20 Ultra... and I also cannot make or receive calls via Xfinity Mobile WiFi. I have very poor cellular service in my home, so I'm definitely needing the WiFi calling to work well. I have very strong Xfinity WiFi throughout my home, but I still have dropped calls (or no calls at all) on my Android cellphone... even though the words "Xfinity Mobile WiFi Calling" are continuously scrolling across the top of my Samsung Galaxy S20 Ultra.
Does anyone have any advice or a fix for "Xfinity Mobile WiFi Calling" on an Android device like the Samsung Galaxy S20 Ultra? Thanks in advance for any assistance you can render.
