iPad/iPhone with her Apple id? I assume these kids who facetimed you are people she knows?
We have an ipad and whenever my wife logs into the ipad with her Apple ID, her information from her iPhone is transferred to the iPad. Even texts sent to her iPhone will show up in both her iPhone and the iPad.
This is just a guess as to what it may be, but I'm only assuming these people are people your daughter knows.
if not, then I'm sorry as I have no clue. Sorry.
I received a call from my daughters number. After getting hung up on several times I got ticked. Then I get a facetime call from her number and I answer at which I hear a kid say "Oh my gosh it worked!" and then they hung up, My first thought was she had lost her phone and they had found it. So I facetime them back and this time I talk to a young girl who was clearly nervous about speaking with me. Come to find out they had somehow accessed my daughters contact list and were calling her contacts using her number. And for the record they did not access her cloud. She has a very crazy password like you get with a program key so there is no way some junior high kid that lives 200 miles south of us got that info. AT&T says it's a app. We are concerned because she does not want her kids getting ahold of this app. We are trying to find the name of the app to warn other parents. Anyone got any suggestions?
