The other person that you are trying to Message with must be registered for Messages on their device. Once they have registered and set up messages, you should be able to contact them.
Messages only works with other iOS devices as well. You cannot message a user with an Android phone.

WEll, I send messages to everyone on my iphone, just cant get certain ones on the ipad. Only 4 or 5 people so far can get my messages and respond on ipad. All the people have iphones and I use facetime to talk to them, but no imessages.....frustrating. I have read all the articles and tried my best. I might go straight to the apple store locally, and see if they can help me.
