iPhone Duo: UK Pre-Order Guide, Prices & Best Deals

iPhone Duo: everything UK buyers need to know.

The iPhone Duo is Apple’s first foldable iPhone – a book-style design that opens from a 5.4-inch cover screen into a 7.6-inch folding inner display. Pre-orders open in the UK on Friday 16 October at 1pm, it goes on sale on 23 October, and early supply is expected to be tight. Here is how UK buyers can be ready – and how a trade-in can take a serious chunk off the price.

How to actually get one on launch day.

Apple is reportedly managing supply constraints, so day-one stock will go fast. Complete Get Ready now so your configuration and payment are saved, be ready at 1pm sharp on Friday, and decide your fallback (second-choice colour or capacity) in advance. Orders placed in the first minutes get the first delivery wave; later orders may slip into November.

The smart way to fund it: trade in your current phone.

A £1,999 phone sounds different when your current handset covers a third of it. We pay up to £700 for an iPhone 17 Pro Max, £520 for an iPhone 16 Pro Max and £420 for an iPhone 15 Pro Max – guaranteed prices, locked for 14 days, paid the same day your phone passes checks. That 14-day lock matters here: get your quote today, order your Duo on Friday, and send your old phone once the new one arrives. Not sure what yours is worth? See our full trade-in value guide.

iPhone Duo contract deals.

UK networks are expected to list iPhone Duo contract deals from pre-order day. We will compare them here as they go live – check back from Friday, or browse all Apple pay monthly deals in the meantime.
