Works great when it works.. when I traveled to Mexico for vacation, all RCS texting broke. The messages app added +52 to all numbers. There was no way to manually edit the number even after deleting the contact. I tried to email support but ofcourse I get a reply that the developer email on the play store is "no longer being monitored." How do you not update info in your own app. Google literally owns the play store. I had to delete all messages and re-create contacts to fix RCS.
