If you’ve signed up with AT&T Next Up Anytime1, you won’t have to worry about the remaining balance of your installment plan. Next Up Anytime allows you to upgrade your cell phone anytime (after making your first payment) as long as you turn in your current phone (with a maximum three upgrades in a 12-month period).
If you don’t have an early upgrade program on your account and would like to upgrade your cell phone, you’ll either need to pay off the remaining balance on your old phone at checkout or pay off your remaining balance ahead of time.
