My one friend doesn't get my messages?

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.

Are you SURE he isn't getting your messages? Are you sure he hasn't blocked you? Have you sat right down next to him, texted him and looked at his phone?

Try you and him both reset apn to default on phones. That may fix the issue

  • Why do some of my messages to my friend not display the delivered message? They don't say delivered or not delivered, it's just blank. The one above it says delivered that I sent two days ago but this one doesn't. This happens fairly often with this friend… I know her phone isn't dead since she's been posting and liking my photos on ig but it still doesn't say delivered under it. She has an iPhone 6s if it helps.
  • Why did my friend's messages send twice? I have an iphone and my friend has an android phone and he sent me this one message on regular message and it got sent twice why did it send twice to begin with?
  • My iphone 4 doesn't notify me when I get text messages? It seems ever since I've downloaded the iOS7 update for my iphone 4, text messages sent to me don't notify me when received. No vibrate, no noise, not even a banner on my lock screen. My phone won't even tell me I have any unread messages until I go to my messages and then they will appear. What is weird is that other stuff notifies me like Facebook and games. Has anybody else had this problem and if so how can I fix it?
  • I'm receiving my friend's messages? My friend borrowed my phone and put her SIM card in it at the weekend but when she returned it she took out her SIM card and I put mine back in. For some reason though, I'm receiving any texts she gets from iPhones through iMessage and she's not receiving them so she can't talk to anyone with an iPhone because I get the messages instead of her. Any idea why this is happening or how to stop it?
