A:Answer Att did away with 2 year contracts in January 2016. You have to pay full price, either one lump sum or 0 percent finance with Next installment payments.
You can keep your grandfathered data plan, but not if you buy at Best Buy; their point of sale computers only allow you to select currently offered data plans. You will have to go to an ATT corporate store and be sure they don't change it on you, intentionally or accidentally. Even if they do, you have two billing cycles to call ATT customer service and get it restored. If you wait longer than two cycles, you will be out of luck.
