IMessage activation problem?

My iPhone pops up with this error message when trying to activate iMessage;
"Your carrier may charge for SMS messages used to activate FaceTime and iMessage"
What does this mean?

Its not an error it's a notification. It's telling you that the company you have your mobile service with may chage you for the SMS messages used to activate these programs - exactly as it says!

  • IPhone 4 'Waiting for activation' on iMessage? My boyfriend has an iPhone 4 with no number. So we tried to use iMessage using his email, and when I turn on iMessage it says waiting for activation and we're wondering what that could be. And when we try to send a text message using iMessage, it won't work. How do we fix that? We tried turning on and off the phone but it won't work.
