Time and imessage can be received by any mobile phone with this id, and if you don't play with Apple settings, people can locate yours, which means he can know where all mobile phone users with his id are.

Set-Privacy-Location Service (off), Information-imessage (off) and FaceTime (off) first, so that you can only receive the information of your mobile phone number.
