My son restored his Iphone 4S (32GB), because it was acting weird. Now, he is not receiving any calls or texts. He also cannot call out with his phone. What did he do?? His device still shows up in my account with usage details. Does he need to re-activate his phone??
Yes he needs to re-activate it. Have him dial *228 from his phone and choose option 1. The phone should be working after it does what it needs to.
