My son logged into his iTunes account with his grandmothers iphone so he could download a song for her ... after that his facetime mesages would go to her phone as well as his. I removed his email address from her phone and it stopped for a while but now her phone number is listed in his imessage and facetime 'send&recieve/you can be reached by imessage at:' .. how do i DELETE her number from this location. It is also listed under 'you can reached by FaceTime at:'
I had him log off both imessage and facetime but as soon as he logged back in the number reappeared.
I want to be sure her phone is no longer associated with my son's iTunes, iMessage, or FaceTime account. Once and for all please.
