T-Mobile's iPhone 17 offer is real, but the word "free" is doing a lot of work. T-Mobile's promotional offer details lay it out: the Apple iPhone Promo with Trade (promotion ID260776, promo code R851) started August 27, 2026 and pays up to $830 through as many as 36 monthly bill credits. T-Mobile's example full price for a 256GB iPhone 17 is $829.99. The device price nets to zero only if your trade-in qualifies for the full $830 and you maintain qualifying service, an active line, and good standing through the full credit period, which may last as many as 36 months.
T-Mobile's own two examples show the spread: an iPhone 15 trades for $830, an iPhone 13 for $630. Same promotion and iPhone 17 price, but different trade values and different net device costs.
What a $630 trade actually costs
Bring an iPhone 13 using T-Mobile’s published example and the math is $829.99 minus $630. That leaves a $199.99 net device cost after all $630 in credits. It isn't free, and the retrieved terms provide no additional credit covering the difference.
Either way, nobody leaves the counter at $0. Due at sale is a $35 device connection charge per line, plus local sales tax on the full, pre-credit $829.99. T-Mobile doesn't publish a rate, so do that arithmetic yourself: $829.99 times your local sales-tax rate, plus $35.
Bill credits can create a 36-month string
You don't get the discount at checkout. It arrives as up to 36 monthly bill credits, and T-Mobile says the credits may take two billing cycles to start. The promotional line has to stay active and in good standing throughout. Paying the device off early ends the credits. Canceling the entire account before all credits arrive stops them and makes the remaining device-financing balance due.
Switching carriers or dropping qualifying service can end eligibility for the remaining credits, and paying the device off early ends them. If the entire account is canceled before all credits arrive, the credits stop and the remaining device-financing balance becomes due. Experience More 2.0 itself has no annual service contract or early-termination fee; the verified packet does not establish that point for every other qualifying plan. Even so, collecting the full device promotion can require maintaining the qualifying line and account in good standing for as many as 36 months.
The service requirement is where the money is
The promotion requires qualifying credit and service costing at least $85 a month with AutoPay, on Experience More, Experience Beyond, Go5G Plus, Go5G Next, Better Value, or a higher qualifying plan. T-Mobile's plan page lists Experience More 2.0 at $90 for one line before AutoPay or other discounts. On top of that sit a $4.49 monthly Regulatory Programs and Telco Recovery Fee per voice line, typical federal and local surcharges of $0.36 to $4.79 per line, and government taxes that vary by location.
At the currently listed one-line rate before AutoPay, $90 × 36 is $3,240. At the current $4.49 monthly recovery fee, 36 months would add $161.64, producing an illustrative $3,401.64 before taxes, other surcharges, and the AutoPay discount. T-Mobile says AutoPay can reduce the price by $5 per line, up to $40 monthly, when paid through an eligible debit card or bank account. For one line, that would reduce the $90 base price to $85, or $3,060 over 36 months. These are illustrations using current figures, not guaranteed bills.
One ambiguity to resolve before signing: the terms we found don't say whether the $85 threshold is measured per line or per account.
The retrieved T-Mobile terms list no end date
The retrieved T-Mobile terms publish no end date for ID260776. They call the promotion limited-time and subject to change, which is not the same as stating an exact deadline.
Mashable’s syndicated report via Yahoo Tech separately says an iPhone 17 Pro is free with a number transfer to Experience Beyond and no trade-in. The verified T-Mobile terms in this packet cover the trade-in promotion and do not confirm that separate no-trade Pro claim, so treat it as unverified here.
Other limits worth knowing:
- Maximum four discounted devices per account.
- The promotion may not combine with some other offers, discounts, or promotions.
- The promotion requires qualifying credit, and the terms we reviewed include no full table of eligible trade-ins and their values.
Before you buy
Three checks, in this order:
- Get your exact model appraised at the full $830 — in writing. Without a full-value trade, the leftover balance is yours, and T-Mobile's published terms don't list every device's value.
- Confirm you can maintain qualifying service costing at least $85 a month with AutoPay for the full credit period. If there's a real chance you'll leave, downgrade, or pay off early, price the deal at the credits you'd actually collect.
- Budget the counter cost: $35 per line plus sales tax on the full $829.99, payable today.
This deal fits an existing customer on a qualifying plan — or a switcher who independently wants that service — with a qualifying trade-in valued at the full $830 and no plans to leave before the final credit, which may take as many as 36 months. Without the full $830 trade value or continued eligibility through the credit period, the device price will not net to $0; the $35 connection charge and applicable tax remain due at sale regardless. The retrieved T-Mobile terms do not state an exact end date, and the limited-time offer is subject to change, so verify availability before buying.
