AT&T is offering up to $800 per line to help customers switch from another carrier. Get an iPhone 17 Pro for $0 per month at AT&T when you trade in an eligible device and sign up for a qualifying unlimited plan on a 36-month installment agreement. This amounts to a $1,100 discount, assuming you meet the requirements. It may be especially enticing for new customers, but existing AT&T customers on the Unlimited Starter or Starter SL plan can also benefit by receiving up to $830 on the iPhone 17 Pro with a $130 or higher trade-in value. If switching from another carrier, AT&T will cover up to $800 per line to end your current contract.
