Imessage on my iphone 4 isn't working

Last night i texted my friend asking him what the homework was. I didn't receive a message in response from him but when I got to school he showed me that he sent it using imessage. My imessage was off and when I tried to turn it on it wouldn't activate!

Have to have Apple ID and password to turn on. But if you didn't get the message, that's something else.

First, if you didn't get a message, that's something different. Or, if your message didn't send, you can reset network settings to fix that. The iMessage thing, enter your Apple ID and password. It may take a few moments for it to activate. FaceTime as well.

  • Why isn't my imessage working on my iphone 4 My imessage hasn't been working for about 5 days now. When i send a text to people who have i phones its sends as a text message. I even tried turning the imessage button one and off in the settings tab. I'm connected to a Wi-Fi as well. Can anyone help me imessage again?
  • Why isn't my iMessage working Okay so I went away for a few weeks and now that I'm home I want to use iMessage on my phone again (iPhone 3) but it was off so i just thought that it turned off automatically when I went overseas but when I turned it on again it wouldn't work; it just sat there with "waiting for activation… " on the screen and not actually working. So I'm just wondering WHY this is and how I can fix it? Cheers.
  • Why isn't my iMessage working on my iPhone 5? It's fully updated as far as iOS goes. I was on my run today and literally it just stopped working out of nowhere. Looked online for troubleshooting but Apple doesn't help AND I don't wanna screw my phone up any worse (whatever is going on) by doing something to activate iMessage again. Anybody have a proven trick that may help me get this back on track? Much appreciated!
  • Why isn't my iMessage working? I have an iphone 4 and today all of a sudden my phone started sending text messages instead of iMessages but in my settings it says that my iMessage is turned on so I don't know what to do! No the people I'm texting have iphones i'm not that dumb haha but it's not working with everyone
