Hey, I have had this problem for over 3 weeks now. I've searched all the forums and came up with nothing helpful. Tried every possible solution, nothing worked. My problem is this: My iPhone 5 won't send SMS text messages. I try to send, and the "sending" bar gets to about 95% then says "message not delivered". I am running iOS 6.1 (10B143). I just recently got Verizon's share everything plan so I could text, and I must say, it's very aggravating that I'm not able to. Please help! I'm very frustrated right now and all my searches (I've been very thorough) have come up with nothing.
