Lost capability to text: Contacts show sip:[phone number]@msg.pc.tmobile.com;user=phone

Hello lovelies!

I figured something out! I have been using Samsung messages because that is the best place messaging app to customize. This same issue started happening with my grandfather's contact and I went through the steps Samsung said which were to wipe my phones cache, reset network settings, and repair apps. This did not resolve this issue, BUUUUUT what did resolve the issue was changing my default messaging app back to the regular google messaging app the phone first comes equipped with. I immediately was able to send my grandfather RCS messages. I know I have seen in support threads from Samsung that they keep claiming the issue is Tmobile and MetroPCS, but I almost do not think that is accurate anymore. We need to drill Samsung to see why the google messaging app doesn't do what their Samsung messaging app does do.

Gracias,
