Trade-in your old phone and get a Go5G Plus or Go5G Next phone plan to get the newest iPhone 15 for free. (You'll receive $830 in trade-in credit on a wide range of eligible phones, and the trade-in credit will be applied as a bill credit, with the balance of the offer applied as a bill credit over 24 months.) You can also get this offer on a new line on an eligible plan, or by porting your existing number to a Go5G Next rate plan. It's also worth noting you can get $830 off the 256GB option (dropping monthly payments to $4.16/mo for 24 months) or the 512GB version (which drops to $12.50/mo.) Some exclusions and requirements apply.
