How do I change my iMessage email to my phone number on iPhone

Settings -> Messages -> Send & Receive. Select your phone number for the "You can be reached by iMessage at" section, and for the "Start new conversations from" section. The latter is probably the one you want to change.

I have done this but it isn't allowing me to select my number please help

I'm not sure if you still need help, but you go into the message settings, and it should say something about using your email and you just delete te email.

I have this problem too, it's saying that I cant delete the email and the number is grayed out.

Settings > Messages - iMessage to Off.

Wait 5 minute then iMessage to On and your phone number should be the default.

Is the link you provided for iOS 6.1.3? I just got a new iPhone 5s and I'm running iOS 7.1.2. Sorry for leaving that out.

It is for iOS.

It is not version specific.

Ok, I can't find 'Messages and Settings' in Settings.

Correct.

Nothing tells you to find that.

For iMessaging Activation issues, go to Settings > Messages.

For FaceTime activation issues, go to Settings > FaceTime.

If you want to have your number exclusively in iMessage, you need to disable any e-mail entry under "You can be reached at iMessage at". It will then automatically disable all entries under "Start new conversations from". Taa daa! You have only your phone number active in iMessage conversations!

ommmg thank you for making it easy enough for me to understand I did it ☺
