Apple has introduced the iPhone Duo, its first foldable iPhone, with a $1,999 starting price. U.S. preorders open at 5 a.m. Pacific on October 16, and the phone goes on sale October 23, according to Apple's September 9 announcement. The U.S., Canada and Mexico are among more than 70 markets in the first wave. The phone is not yet available to buy as of September 11.
The outer display measures 5.4 inches, the inner one 7.6 inches, and Apple says a Split View mode lets two apps share the larger screen. It runs iOS 27.1 on Apple's A20 Pro processor, in 256GB, 512GB, 1TB and 2TB capacities.
Two monthly prices, two different transactions
Apple lists the Duo at $1,999, or $83.29 a month for 24 months for qualified customers. It separately advertises Apple Upgrade starting at $57.99 a month for 24 months. Those are not two prices for the same thing, and the gap between them is not a discount.
The $83.29 figure is Apple Card Monthly Installments. Twenty-four advertised payments of $83.29 total $1,998.96, four cents below the stated $1,999 starting price, with the device installments carrying a 0% APR. Qualifying takes credit approval and sufficient credit, choosing ACMI at Apple's checkout, and choosing AT&T, T-Mobile or Verizon there as well, even though the phone ships unlocked. Two details are easy to miss. Taxes and shipping on an ACMI order are charged at the Apple Card's variable APR, not the installment plan's 0% APR. And ACMI isn't available through Apple's special online storefronts; its terms and eligible products can change.
The $57.99 figure is Apple Upgrade, a consumer lease from Klarna — not a purchase and not a loan. Terms run 12 or 24 months, subject to creditworthiness and eligibility, and an eligible carrier is required. Excluding taxes and any trade-in credit, Apple lists typical payments of $82.99 to $132.81 a month on 12-month terms and $57.99 to $92.81 on 24-month terms. That's $995.88 to $1,593.72 over a year, or $1,391.76 to $2,227.44 over two. The cheapest 24-month lease involves about $607 less in scheduled payments than the $1,999 purchase price, excluding taxes and trade-in credit, but it is a lease rather than a purchase. The priciest 24-month lease totals more than the $1,999 purchase price. Apple also warns that ending a lease early and returning the phone may bring a substantial charge, and it hasn't published an expiration date for the current lease pricing.
eSIM, mmWave and a T-Mobile-only feature
Every iPhone Duo is eSIM-only worldwide, so it needs a carrier and a service plan that support eSIM. That's worth confirming before preorders open, especially on a prepaid brand, an MVNO, or a physical SIM you've carried through several upgrades.
Apple says the phone's C2 cellular modem adds mmWave support in the U.S., and that iPhone Handoff will work initially with T-Mobile among U.S. carriers, a launch-day split that leaves AT&T and Verizon customers without it on day one. Apple's battery and performance figures come from its own controlled testing on preproduction hardware. The two cited sources provide no independent testing of the hinge or displays.
Apple enters the foldable-phone category
The Wall Street Journal, in a report syndicated by To Vima, calls Apple's entry a significant development for the foldable category and notes that Samsung released its first Galaxy Fold in 2019. The Journal also reports that John Ternus, who became Apple's CEO the week before, presented the device; Apple's own release likewise identifies Ternus as CEO.
What actually needs deciding before October 16
Nothing is purchasable yet, so the work this month is readiness rather than checkout:
- Confirm eSIM support on your current carrier and plan before preorders open, particularly on prepaid and MVNO service.
- Decide which transaction you want. ACMI is a purchase of an unlocked phone. Apple Upgrade is a lease, not a purchase or loan.
- Expect a carrier prompt. ACMI asks you to select AT&T, T-Mobile or Verizon at Apple's checkout even though the device ships unlocked.
Neither source establishes carrier trade-in values, carrier installment offers, or activation fees for the Duo. Those are questions for whichever carrier you land on, and Apple's announcement doesn't answer them.
