Yes it was extremely annoying. Had to dial in and do some very hacky phone code entry. Then it would work for a few months until they tweaked something on back end and it would cut out again. It was a shame as I actually liked Samsung Messages; I know people criticized it as duplicative, but it was cool how it would sync across devices, fit in with native one UI style, etc.
That may have been my problem, I had no option for RCS at all on my unlocked s20 through tmobile
It appears so. I had an unrooted S20 with T-mobile and it did have the option to enable RCS (tried it for a bit but it was pretty useless)
