S4's stopped sending MMS
Hi, I have two Galaxy S4's. An S4 Active and an S4 mini. Within the past week or so both of them have stopped sending or recieving MMS messages. I know one stopped for sure after an AT&T software update, and I assume the other was the same although I don't recall seeing an update, but I assume it happened around the same time as the other. I have looked at other forums and tried some various tricks but nothing seems to work. Any ideas??? This is extremely frustrating! Thanks.
