I'm in a family plan with my mom and dad but I got an iPhone and never got in a contract only my parents because they didn't have phones. So i'm eligible to get a discounted price of the iPhone. if i preorder how does it work? I'm under 18 my dad is currently truck driving and won't be back in two weeks. How can I get into a contract for 2 years without my dad there to sign it? And if I preorder online how does it work?
