Even worse, I'm migrating to an all-Voip solution because my carrier refuses to support VoWifi/VoLTE and it solves my coverage issues.
The only disadvantage is I'm forced to fall back all the way to SMS. No MMS even, and what about RCS, the new texting system that works through your data connection well there's no support for that aside from using Google Messages and the SIM that's in the phone!
