Final answer:
The query relates to the AT&T NEXT program, which lets customers trade in their phones for an upgrade. The process includes paying off the current device and meeting specific conditions for trade-in eligibility.
Step-by-step explanation:
The question pertains to AT&T NEXT, a program that allows AT&T customers to trade in their current phones and upgrade to a new device before their contract ends. This program typically involves paying off your current device through monthly installments and then being eligible to trade it for a new model after a certain percentage of the device has been paid off. Customers have to meet certain conditions related to their current service agreement and the condition of the device they are trading in.
To take advantage of the AT&T NEXT upgrade option, you should first ensure that your current phone is in good working condition and that you've paid off the required portion of your existing installment plan. After that, you can select a new eligible device and begin a new installment plan, which allows you to get the latest phone models without having to pay the full price upfront.
