Iphone 5s sending but not receiving sms text messages, when iMessage still works.
My iphone 5s has recently hit a big texting problem. when texting someone for a while it would say "not delivered" on both of our phones and i would receive many duplicates of his text messages all at once when they finally did come through. But now everything i send does go through and they are received, but i receive none of my own sms text messages. iMessage works just fine. This has gone on for several days, i've taken out my sim card and put it back in, updated my phone, toggled all possible related settings and reset my phone several times.
