Please can anyone out there tell me how i "sign in"? Everytime i try to send the message it come s up "Your Imessage account is not signed in" Then when i try to sign in another window pos up showing me my account details but nothing about signing in?
New phone? Have you signed in to iTunes? FaceTime? iCloud? Go to settings>Messages>Toggle iMessage on. Then go to "Send and Receive" and tap that.
Then add in your Apple ID email in the top space.
If one is there, tap it and choose "sign out".
Then add your Apple ID back in. Then make sure iMessage is turned on.
