Which one is right for you?
Get the iPhone Duo if…
- you want a phone that opens into a small tablet
- you read, draw or watch a lot on it

What it really costs you
It's yours
You own the phone outright. There's no contract and nothing to hand back.
Sell it back when you want
After 1 year, 2 years or never. We'll always make you an offer.
Unlike a lease
With a lease or upgrade plan you return the phone and never own it.

Estimate based on what we pay today for the same phone one or two years older, in Good condition. Your actual offer depends on its condition when you send it in. Prices update every night.
Should you wait for the Duo?
Wait if the folding screen is the reason you want a new phone. Nothing else does that. If you mainly want a big screen, a great camera and a battery that lasts all day, a Pro Max already does all three. Sell a used 16 Pro Max back to us after a year and it costs you about $360. The Duo costs $1,999 up front.
