My phone suddenly stopped letting me receive texts from non iPhone users yesterday. Since then, I have powered my phone on and off, reset the network, and power cycle. My mother has been in the hospital and I have to be here with her all day. I have no time to go to a verizon store. I've only had the phone a week and I'm really disappointed with this. Seeing my mom is in the hospital, I really need this to be working, but I'd don't even know of something else to try.
Ktoole, I can understand how frustrating this could be. How long has this been an issue? Have you ever been able to receive texts from non-iPhone users? Do you have iMessage on or off? Have you tried to restore the phone through iTunes?
