My iPad can't use my phone number to send iMessage with after update to 6.1.3. I have tried turning it of and back on again but i can only choose my email to send/recieve from.
Does anyone know what is wrong and how i can fix it?
Read this kb article and make sure that you go to the very end of the article to find out what to do. You might have to sign out of Messages on all of your iDevices in order to link the iPhone number back to Messages on the iPad. You should be able to do that if you follow the steps at then end.
