    Wi-Fi Calling Error: REG90 "Unable to Connect"

      I just switched from Sprint to T-mobile. Got a new phone and am trying to use wi-fi calling because of the poor reception in my building. I keep getting the above error message every time I switch the Wi-fi calling mode on. How can i get this fixed?
