This promotion applies to any smartphone AT&T sells, and gives customers access to the latest devices at a fraction of the cost or, in the case of smartphones priced under $99.99, for free. To take advantage of this offer, customers are encouraged to visit any AT&T company-owned retail store or participating authorized dealer with their previous smartphone that is no more than three years old and in good, working condition. In stores, upon trading in their old phone, customers will receive the $100 credit on-the-spot and can use it immediately.
Some trade-in phones may have a value higher than $100. In this case, customers will receive the credit at the higher value.
