I have verizon and ive been having the same issue happening to me. I started using google messages and it seems to be helping. but im sure its something carrier related.. just not sure how long it will be.
Me too, switched to Google texts. It worked the first time, then got stuck again. Can't disable Samsung text app when Google text is default. Maybe this causes problems?!?!?
I've spent hours diagnosing someone's issue, I just wish all the players would get together and figure this out and fix texting without all the finger pointing.
