T-Mobile is advertising $1,200 off the iPhone Duo with no trade-in required. The catch is in the terms. You have to add a new line, port in a number from another carrier and be on an Experience Beyond plan. The discount arrives as up to 36 monthly bill credits, not as a lower price at checkout.
What T-Mobile’s $1,200 iPhone Duo deal actually costs
T-Mobile’s fine print lists the iPhone Duo 256GB at $1,999.99 on its finance agreement. Spread across 36 months, $1,200 in credits works out to about $33.33 a month. That leaves roughly $799.99 for the phone itself over three years. You also pay tax on the full $1,999.99 at the time of sale.
- Plan: $100 or more per month with AutoPay, plus taxes and fees
- Qualifying plans: Experience Beyond 2.0 for new and existing members; Experience Beyond and Go5G Next for existing members only
- Line rules: add a new line and port in a number from another eligible carrier
- Due at sale: tax on the pre-credit price, plus a $35 device connection charge
- Credit timing: allow two bill cycles; the line must stay active and in good standing
- Limit: up to four discounted devices per account
The credits stop if you leave
The credits only keep coming while you stay. If you cancel your entire account early, the credits stop and the remaining device balance becomes due. Paying the phone off early ends the credits too. That makes this a three-year commitment marketed as a discount. Anyone likely to switch carriers or pay off the phone within three years should expect to lose part of the $1,200.
T-Mobile also says shipping is taking longer than usual because of demand. It will still honour the offer, and the credit terms begin only when the phone ships. That lines up with Apple’s own backlog, with online iPhone Duo orders now quoting late January 2027 delivery.
How it compares with AT&T
AT&T also offers up to $1,200 off the iPhone Duo as 36 monthly bill credits. Its version needs a trade-in and a Premium 2.0 plan, as we covered in our AT&T iPhone Duo deal breakdown. T-Mobile drops the trade-in but ties the credits to a new, ported line. Buying through Apple has its own catch, since the $57.99-a-month option is a lease, not a purchase.
T-Mobile describes the offer as limited time and subject to change. If you’re weighing it, check the current terms on T-Mobile’s page before you port your number.
