So my dad thinks he's real funny and turned on the AT&T famymap crap. He can basically see wherever I am whenever he wants too. I'm 18, so he shouldn't be pulling this or caring what I'm doing, but he says if he's paying for the plan he can do whatever he wants. So, there are 2 ways to track people on a cell phone, gps and cellular triangulation. Gps is precise down to like 5 feet or something and cellular triangulation is within like a mile. The thing is, is that I'm rarely where I say I'll be, and I don't want him knowing that. So will airplane mode do it? Or do I have to just shut my phone off?
