There’s also a promotion for Samsung’s Galaxy S23 at AT&T. If you’re willing to trade in an older device, you can pick up the flagship smartphone for free.
AT&T does require you to hand over a suitable device for the full trade-in value. However, different devices will net you different discounts. For example, a Samsung Galaxy S20+, 128GB, in good condition equates to $800 off — resulting in a free Galaxy S23 — whereas older models, such as the iPhone 7, might not be eligible for this deal.
You will also need to sign up or upgrade to an Unlimited plan.
