IPhone5 will send but not receive Text messages. Specifically, I can send my grown son text messages, but he can not reply to them, nor can he send me new texts. He and I are both on Verizon, and he has a Droid phone. His texts can be recieved by his mother, who can forward them successfully to me. When I initally received the phone (Dec 2012) I could receive and send texts with my son with no difficulty. The trouble began (as near as I can tell) when my phone was upgraded to 6.1.1. This is a significant problem and I would like it resolved as soon as possible.
