[AC Question]

I have had my Galaxy S4 Active for a little over a year now, and I really love it. However, the past few days people have been calling me wondering why I have not been returning their texts... I can send text messages and people will receive them on their phones but when they text me back it never shows up on my phone...I can however call and receive phone calls. I sat on the phone with ATT for an hour and they couldnt figure it out either...any suggestions as to what is going on? I really dont know what is going on. Any advice helps thanks!

Assuming you have enough free internal space for new texts (if not, clear up some space - back up all your texts and delete everything before a month ago or so, to start), ask your local AT&T store where the nearest Device Support Center is (if the store personnel can't figure out what's wrong) and ask them (the DSC) if they can help you.
