Where to buy the iPhone Duo

Checked Oct 31, 2026. Every offer below carries the date it was confirmed, and carrier deals change often, so check the offer page before you order.

In the US, the iPhone Duo is sold by Apple, the big carriers, Best Buy and a few smaller wireless brands. The phone is the same everywhere. What changes is whether it comes unlocked, how long the payments run, and what you have to sign up for to get a discount.

Apple: the only clean unlocked option

Apple sells the iPhone Duo on its website with a Connect on your own later option, at $1,999, $2,199, $2,599 and $3,199 for 256GB, 512GB, 1TB and 2TB, per Apple's iPhone Duo store page as of Oct 31, 2026. The same page offers AT&T, T-Mobile and Verizon versions, and Apple notes the iPhone Duo uses eSIM only, with no physical SIM support.

The Shortcut lists the Apple Store app and Apple's retail stores as other ways to buy from Apple. Walk-in stock is tight: Apple told MacRumors that stores would have "limited iPhone Duo available for walk-in customers" at the Oct 23 launch, and the US was on the walk-in list.

Shipping is the bigger catch. On Oct 16, Apple's US online store showed a Jan 25, 2027 shipping estimate for every configuration, according to MacRumors. Apple's store page doesn't publish a fixed date, so check the estimate at checkout.

For financing, Apple's payment plan page lists 0% APR Apple Card Monthly Installments for iPhone over 24 months as of Oct 31, 2026, but it doesn't show a monthly figure for the iPhone Duo, and Apple says the terms can change. The same page says an iPhone bought this way is always unlocked, yet you still have to select AT&T, T-Mobile or Verizon at checkout, and prepaid plans don't count.

Apple's trade-in credit runs $35 to $885 toward the iPhone Duo, per Apple's store page as of Oct 31, 2026. Apple says the value depends on your device's condition, year and configuration.

Carriers: bigger discounts, longer strings

AT&T lists the 256GB iPhone Duo at $1,999.99, or $55.56 a month over 36 months at 0% APR, on its iPhone Duo page as of Oct 31, 2026. The headline offer is up to $1,200 off as bill credits, with a trade-in worth $230 or more and an eligible plan. MacRumors reported on Oct 16 that the full $1,200 needs Premium 2.0 or higher, with up to $930 on Extra 2.0 and up to $500 on Value 2.0; Apple's store page showed the same tiers on Oct 31, 2026.

T-Mobile offers up to $1,200 off with a trade-in in any condition for new and existing customers on Experience Beyond 2.0, per Apple's store page as of Oct 31, 2026. MacRumors (Oct 16) and Tom's Guide (Oct 23) reported up to $1,000, so confirm with T-Mobile before you trade in. Apple's page also says T-Mobile's 36-month financing is limited to certain plans, with 24 months on others, as of Oct 31, 2026.

Verizon offers up to $1,000 off for new or add-a-line customers on Unlimited Ultimate, per Apple's store page as of Oct 31, 2026, matching the $1,000 new-line offer Tom's Guide reported on Oct 23. Through Apple, existing Verizon customers see $150 to $840 depending on plan and trade-in, as of Oct 31, 2026. Verizon's iPhone Duo page showed $55.55 a month for 36 months at 0% APR on Oct 31, 2026, with Star White shipping between Dec 12 and Dec 30.

Xfinity Mobile offers up to $1,000 off with a trade-in, or $400 off without one, for new Mobile Plus customers and some existing members, per Tom's Guide's Xfinity report (Oct 8). Tom's Guide listed the same up to $1,000 offer on Oct 23 but didn't give the credit schedule.

In practice, the $1,200 and $1,000 figures are three-year commitments to a specific plan. That's worth it if you'd stay anyway. If you switch carriers every year or two, it probably isn't.

Best Buy

Best Buy sells the iPhone Duo with carrier activation. Tom's Guide lists up to $1,200 off with activation and a trade-in as of Oct 23. Tom's Guide doesn't say whether Best Buy sells an unlocked iPhone Duo, so treat Best Buy as a carrier purchase with a different checkout counter.

Prepaid and smaller carriers

Tom's Guide (Oct 23) lists a Visible offer of $480 back over 24 months on the $45-a-month Visible+ Pro plan, but says it wasn't available yet. Red Pocket Mobile was listing the iPhone Duo at $1,899, $100 off, with no port or trade-in required, per the same Oct 23 roundup. As of Oct 23, Mint Mobile isn't running an iPhone Duo deal, but Tom's Guide says you can bring an unlocked iPhone Duo to its plans.

Since the iPhone Duo is eSIM only, setting up a smaller carrier means an eSIM transfer. More on that in our guide to moving your eSIM.

What about Amazon and Costco?

Tom's Guide's Oct 23 roundup lists Amazon only for iPhone accessories, not the phone itself. MacRumors also lists Amazon, Best Buy and Target only for iPhone Duo cases in its Oct 23 deals post. As of Oct 31, we found no source confirming that Amazon or Costco sells the iPhone Duo, so be wary of third-party listings.

Which route makes sense?

If you want flexibility, buy unlocked from Apple and accept the wait. If you're staying with your carrier for three years and have a recent phone to trade in, the top carrier credits are worth more than Apple's trade-in on paper. If you're on a prepaid or smaller carrier, an unlocked phone from Apple is the straightforward path.
