I think I found the solution to the texting issues I've been having. I've tried 4 different Messenger Apps and ran into the same issue with each app. Was just about ready to try switching carriers and was asking others around work about Sprint, T-Mobile, ect and was told by one person that had AT&T that she was having the exact same issue and just did a Network Reset. >Settings>Backup & reset>Network settings reset> "tap" NETWORK RESET So I did the Network Reset and so far....... that has seemed to fix the problem. If anyone here is having a problem receiving texts, might give this a try before anything else. Remember to completely shut off your phone for a minute after you do this.
