IMessage and Facetime is not activating?

For some strange reason, my iMeaasge and Facetime is not activating. It's been like this for two days. So basically, it says "Waiting for activation" once i turn them on.
I've tried EVERYTHING. I've reset the network settings, turned airplane mode on and off, and i've reboot the phone may times. I have an iPhone 4 running on iOS 6.1.3.

It was working PERFECTLY fine 2 days ago.

You may need to check your network, it's better if you try to activate through Wi-Fi if the problem still occurs contact your service provider

  • Why is my iPhone 4S not allowing me to FaceTime or iMessage? I have about five people who have an iPhone on my contacts. My phone will not let me send and iMessage or FaceTime them! What's wrong with it? I'm getting annoyed because I have FaceTimed and iMessaged last week and both stoped working Saturday. The only thing my phone sends are text messages. Can anyone explain why?

  • IMessage on iPhone 5 not activating? I just got a new iPhone 5 for my daughter, but for some reason, the iMessage doesn't work. It will always just say "waiting for activation". I've tried activating it in many ways, but it still doesn't work. Any suggestions? I should mention that the phone doesn't have a number or plan yet, is that necessary for iMessage?
