So my dad said my company can still buy a phone from at&t but can't have a contract with it or it would mess up the family contract with t-mobile and t-mobile is great and all but i don't like their phones they suck. and i wanted an iphone from at&t but ONLY THE PHONE and not contract data plan. i just want the phone from at&t and get data plan and contract with t-mobile, How can i do that. Give me all the information as clear as possilbe please
