Alright heres the situation I was wondering if I could buy an unlocked phone to add to the fifth line of my AT&T family plan without having to sign a new contract. Currently I have 3 lines on the family plan but for the fifth one (if I were to buy from att) I would have to sign a new contract. This would make my family plan have 2 different contracts start and end at different times. I was wondering if I could get an unlocked phone and buy a sim card and not sign a contract until my other 4 lines' contract expires. Do you think this is this possilbe? I've already chatted online with support and they said I would have to call in support to find an answer. I don't really feel like being put on hold for like an hour.
