My friend & I both have iPhones 5s. We got each other's messages fine until recently I have been getting his messages, but he doesn't get mine. Even when it shows up as blue and it says it sent, he still doesn't get them. I have tried resetting the network settings, deleting the conversation, EVERYTHING. I have MetroPCS as my carrier, if that helps. Many thanks!
