Family Sharing Problem with Child's iPhone Apple ID
It seems that my son's iPhone Apple ID is paired with my and my wife's phone. An example is if I call my wife's phone, it will also ring his phone. Texts are seen on all 3 devices, as we share the same Apple ID.
So if I want to change my son's Apple ID...1)Does he need his own email address, 2)How then do I change just his Apple ID, 3)Will changing his Apple ID cause his phone to lose any data, and/or purchases from games or apps??
Any insights are greatly appreciated!
