RCS messaging has become the default messaging platform for Android phones. Last month mine and my wife's phone (both Moto G7+) briefly had RCS messaging for two full days before it stopped working. At first trying to access this function via the settings gave me an error "your carrier does not currently support this function." The next day it worked again, then again stopped working. This time the warning changed to "your device does not currently support this function." The second warning I know is untrue as it worked just fine the day before.
The only answer has to be cricket is actively blocking this function. I don't know why. Maybe it's a stall until they find a way to monetize it or maybe they're doing it to force people to buy one of the few phones they allow it on. Doesn't matter to me, I just want it to work.
Barring that, I want an explanation why cricket is blocking it.
