Checked Nov 4, 2026. Prices and offers below are as of Nov 4, 2026, from T-Mobile's iPhone Duo page unless a dated report is named, and T-Mobile changes deals often.

T-Mobile opened iPhone Duo pre-orders on Friday, Oct 16 and started availability on Friday, Oct 23, per T-Mobile's launch announcement. Customers could pre-order in the T Life app or online at t-mobile.com.

Price and financing

As of Nov 4, 2026, T-Mobile's iPhone Duo page lists full prices of $1,999.99 for 256GB, $2,199.99 for 512GB, $2,599.99 for 1TB and $3,199.99 for 2TB, plus tax. Over 36 months before discounts, that's $55.56 a month for 256GB and $61.12 for 512GB with $0 down, while the 1TB and 2TB models show $70.84 a month with $49.99 and $649.99 due today.

T-Mobile adds up to a $35 device connection charge and says 0% APR applies for well-qualified buyers. Apple's own US prices are $1,999 for 256GB, $2,199 for 512GB, $2,599 for 1TB and $3,199 for 2TB, per MacRumors.

T-Mobile's financing option is EIP Flex 36, which spreads a new iPhone's cost, including taxes and fees, over 36 months. T-Mobile says it's available to well-qualified customers on eligible devices, and that finance charges may apply based on creditworthiness, according to the announcement.

The trade-in and new-line offers

T-Mobile's iPhone Duo page listed 14 offers as of Nov 4, 2026, each paid as up to 36 monthly bill credits for well-qualified customers, plus taxes and fees. The top two are up to $1,200 off with an any-condition trade-in on Experience Beyond, or up to $1,200 off with a new line and number port on Experience Beyond, no trade-in needed.

Below those, T-Mobile lists up to $1,000 off on Experience Beyond with 55+, Military, First Responder or Student Savings, up to $930 with a trade-in or a new line and port on Experience More or Experience Beyond, and several $730 offers, including one with a new line and trade-in on most plans. With the promotion on Experience Beyond, the page shows $22.22 a month for 256GB, $27.78 for 512GB and $37.50 for 1TB and 2TB.

The headline number grew after pre-orders opened. On Oct 16, MacRumors reported up to $1,000 off with an any-condition trade-in on Experience Beyond, and by Oct 29 TechRadar reported the top discount had risen $200 to up to $1,200 with either a trade-in or a new line.

Tom's Guide's Oct 30 report filled in the trade-in conditions at the time. The full $1,200 needed a listed Apple or Samsung trade-in, with the iPhone 15 Pro and Pro Max as the oldest eligible iPhones, and the Galaxy S24+ and Z Flip 5 or newer on the Samsung side, with smaller credits of up to $930 or $500 for other trade-ins.

Which plans qualify? T-Mobile's page names Experience Beyond for the $1,200 offers. Tom's Guide reported on Oct 30 that new customers needed Experience Beyond 2.0, from $100 a month for one line, while existing customers could use Experience Beyond 2.0, Experience Beyond or Go5G (Go5G from $75 a month). T-Mobile's announcement adds that if you cancelled lines in the past 90 days, you may need to reactivate them first.

What happens if you leave or pay off early

T-Mobile's iPhone Duo page says that if you pay monthly and cancel wireless service, the remaining balance on the device becomes due. The fine print in T-Mobile's Sept 10 announcement, which covers its iPhone offers generally rather than the Duo by name, says bill credits end if you pay off the device early. It also tells customers to contact T-Mobile before cancelling an entire account to continue the remaining credits.

The Spanish-language version of the release spells out the alternative: the credits stop and you owe the balance under the financing agreement. That release covers both the iPhone 18 Pro and the iPhone Duo, but its bill-credit offers name only iPhone 18 Pro models, so confirm the Duo offer's own terms at checkout.

The catches

Credits arrive monthly, not as an instant discount. Tom's Guide summed up the trade-off as an "expensive 3-year contract with one specific carrier," and that's fair: the full $1,200 likely only reaches you if you keep the line and the plan for all 36 months.

The top offers also need Experience Beyond, and that plan cost runs alongside the credits. Trade-in rules were narrow too: with the iPhone 15 Pro as the oldest eligible iPhone in Tom's Guide's report, it appeared an iPhone 14 or older wouldn't unlock the full $1,200 through a trade-in.

Then there's timing. As of Nov 4, 2026, T-Mobile's page shows every storage tier as back-ordered, and Tom's Guide reported on Oct 30 that T-Mobile's delivery estimates were Dec 31 to Jan 6 for every color and storage size.

eSIM setup on T-Mobile

The iPhone Duo has no SIM tray option. Apple's spec page lists dual eSIM with two active eSIMs and says the phone isn't compatible with physical SIM cards. T-Mobile says the eSIM-only design frees internal space to maximize battery capacity.

Coming from Android, Apple's Android eSIM transfer document lists T-Mobile among the US carriers that support moving your SIM directly, including during new iPhone setup. You need an iPhone on iOS 26 or later, an Android phone on Android 16 or later, and both on Wi-Fi with Bluetooth on. If your phone doesn't support it, Apple says to contact your carrier. More in how to move your eSIM, switching from Android and setting up a new Duo.

One T-Mobile extra: iPhone Handoff lets customers with two compatible iPhones use one T-Mobile number on both and pick which is active, per the Spanish-language release. T-Mobile is introducing it at $5 a month, and says it works on any iPhone with iOS 27 and on the iPhone Duo from day one.

T-Mobile or unlocked from Apple?

Buying unlocked costs more upfront but leaves you free to switch carriers or sell the Duo whenever you like. T-Mobile's credits only add up if you stay, so the deal suits people already happy on Experience Beyond.

Protection is a separate choice. As of Nov 4, 2026, AppleCare+ for iPhone Duo is $329 upfront or $16.49 a month, and AppleCare+ with Theft and Loss is $399 upfront or $19.99 a month, per Apple's AppleCare+ terms. T-Mobile's Protection 360 for the Duo is $26 a month, renews monthly and can be cancelled anytime, per T-Mobile's product page, and includes $0 screen fixes, unlimited accidental damage claims, loss and theft replacement and AppleCare Services for eligible devices. The comparison of AppleCare+, carrier insurance and credit card coverage covers how carrier plans stack up.

Bottom line: the T-Mobile iPhone Duo deal is strongest for switchers or Experience Beyond customers with a recent Pro iPhone or Galaxy to trade, who plan to stay three years. If you want flexibility, or might move to a second-generation model early, unlocked is the safer choice. More on iPhone Duo deals.
