Send imessage between iphone, and the display is indeed sent to yourself.

So you can use the email address of * * * as the contact information of imessage. In fact, you can set your mobile phone number as your account, and just go to GM to reactivate imessage. If there is an error during reactivation, restore the network settings and restart, so that you can send imessage with your mobile phone number in the future!
