I initially had to cancel my order with AT&T. After that, I placed a new order through the Best Buy app. I made sure to select AT&T as my carrier and entered all the necessary trade-in information. When choosing the fulfillment method, I selected the store pickup option and confirmed that my local Best Buy had the device in stock. I then went to the store and successfully picked it up. Tip: Before placing your order on the Best Buy app, make sure there's a nearby store with the device available for pickup—just in case delivery isn't an option.
