You can get a phone either for free (chosen among select models), or you get up to $750 off the phone's full price. That's if you trade in an older phone and add an additional line of service to your plan. So, if you already have one phone line, this deal applies if you add a second line. If you pay for two phone lines, it works when you add a third. > Here's how the phones shake out:Free: Galaxy S9, Galaxy S8Up to $750 off: Note 9, Galaxy S9 Plus, Galaxy S8 Active
