IMessage won't send to another iPhone with iMessage?

So my iMessage works to all my friends that have iMessage except one friend in particular. He has iMessage on his phone and can iMessage all his friends but he can't iMessage me. We both have iMessage turned on on our phones but they simply will not iMessage each other.

For some reason this happened with me the other day. There's either a bug with iPhones or the service in the area but don't worry because it will fix itself! Mine did after a few hours. So I would wait and see what happens! It's definitely not a problem with either of your phones.

Usually caused by a bug, and can usually be fixed by both parties turning iMessage off and then enabling it again, once enabled, type a message to the friend in question and wait 5-10 seconds until the green send button turns blue

Is IMessage different than Facebook Messaging? I have a new iPhone, and I keep getting messages from people I don't know including personal ones. It doesn't show up in my Facebook Messages. Can I block these people on IMessage?

  • Why won't my iPhone 4 send pictures on iMessage? It's a new iPhone and it won't send pictures for some reason. It said "not delivered when j try to send pictures". Can someone do a step by step process with me? Like send me everything I have to do?
  • My phone won't send an iMessage to a person with another iPhone when it used to? Ok so me and this person text and we rely off iMessage cuz we both live over seas and iMessage used to be fine for both of us but now for her phone it keeps sending texts and it's costing me a lot of money. I have all my settings on and stuff and I can send iMessages to other people but to her it keeps sending them as a text when me and her clearly can iMessage cuz we both have iPhones. I don't know what to do and it's costing a ton of money for me, and prolly her!
  • My iPhone won't let my send pictures on iMessage? I'm not sure why this happens an I checked all through my settings and I didn't see anything that could be helpfull. I try and press the picture button but nothing happens. It's a "new" used phone but we restarted it so I don't know what the problem is.
