T-Mobile is offering one of the year’s most desirable upgrades for $0: the iPhone 17 Pro, free through bill credits when you add up a qualifying trade-in with T-Mobile’s Experience Beyond plan.

What exactly is that “free” iPhone 17 (Pro) including?
T-Mobile puts the total value of the deal, worth up to about $1,100 in credits, toward a new iPhone 17 Pro over 24 months. You’ll see the credits approximately two billing cycles after activation, provided your account is current, and they also continue even if you switch to an eligible plan. Cancel your phone plan early or switch to a non-qualifying one and you’ll lose any remaining credits; you’ll have to pay the balance due on the phone.
Sales tax on the full retail price is due at purchase, and there’s normally a $35 activation or support fee per line. None of that is out of the ordinary; carrier promos from all three national networks work this way, relying on long-term credits to make sure bills are predictable each month.
The quickest route to eligibility, in detail
- First, make sure you are on—or willing to switch to—T-Mobile’s Experience Beyond plan. That’s the catch to the free iPhone 17 Pro with trade-in. Customers can migrate to the plan if they’re already customers, or add a new line if not.
- Second, secure a qualifying trade-in. T-Mobile relies on tiered trade-in lists along with larger credits for the most recent, high-value flagships in good working order. Think Pro-level recent iPhones and top Android devices from Samsung and Google. Some cosmetic wear is acceptable; cracked screens, activation locks, or liquid damage can disqualify or reduce credit.
- Third, buy the iPhone 17 Pro on an equipment installment plan. The promo credits spread those payments out over 24 months, so that after a couple of years your net device cost is zilch.
- Finally, don’t blow the deadlines on the trade-in. If you’re sending it through the mail, use the provided shipping kit and track your proof. The most common reason credits are clawed back is for devices that arrive late or not at all.
No trade-in? Alternate discounts are available
If you’re porting your number over to T-Mobile and select Experience More or Go5G Plus, the carrier will give you the base iPhone 17 for free — up to $830 off any iPhone 17 model without requiring a trade-in. Not the iPhone 17 Pro for $0, but not bad for customers who don’t have an eligible old phone.
What constitutes a “qualifying” trade-in device
Carriers have their own internal grading and model tiers to calculate what the promo value is. The highest tier is typically reserved for recent iPhone Pro models and current-gen Android flagships; the mid tiers include regular flagship phones from the last few years; low-end, heavily damaged, or broken-down phones would be in the lowest tier or will not qualify. Your device should turn on, have a good LCD, have no activation lock, and not be carrier- or iCloud-locked.
Count on T-Mobile inspecting the device’s condition at the time of receipt. Credits may be adjusted for a phone that isn’t in the stated condition or model. It’s a good idea to take pictures of the device and record the IMEI before you send it.
Why T-Mobile is working so hard — and what you get
Trade-in-driven promos are a customer-acquisition play. T-Mobile has been highly ranked by independent testers such as Ookla and Opensignal for both 5G availability and median speeds in the U.S. It uses that network position to bring switchers to its brand through aggressive offers, “stacking” the devices customers receive, Mr. Connors said. For customers, the math can be irresistible: a flagship phone that is essentially free, spread out over two years, plus a network with widespread 5G coverage.

Meanwhile, Apple’s iPhone 17 Pro would bring you a worthwhile upgrade: faster silicon, improved efficiency, and refinements to the system of cameras — not just a new color. If you produce content on your mobile devices, or really just need long battery life now and then, the Pro model is the sweet spot in Apple’s lineup.
Fine print: fees, credits and plan rules
Credits are monthly, not upfront. Missed payments, plan downgrades, or account closures can end them. At the time of purchase, taxes apply to the full price on all options; activation or support charges may apply. Promotional eligibility can depend upon factors such as AutoPay and an account in good standing. If you return the phone following activation, you may be charged for return fees and credits are reversed.
Also worth mentioning is that phone unlock timing is per T-Mobile’s regular policy, not the promo timeline. If you travel outside the country and want an unlocked device, scope that policy out before committing.
Who should take the deal — and who shouldn’t
If you were already thinking of sticking with T-Mobile for that long, and had a decent trade-in, this is among the lowest effective prices you’ll find on an iPhone 17 Pro.
Families that are consolidating lines in a premium plan usually find the greatest value.
If you prefer prepaid service, like the flexibility of keeping your plan as-is, or upgrade phones more frequently than every two years, you might feel the longer credit schedule is restrictive. In which case, compare the no–trade-in discounts on other plans or buy the phone unlocked and separate from service.
Bottom line: how to walk out paying $0 over time
Switch to the Experience Beyond plan, trade in a recent flagship in good condition, and buy the iPhone 17 Pro on installments, all while having an active account for 24 months. That is the formula, more or less, that’s behind T-Mobile’s free iPhone 17 Pro deal. Read the fine print, hang onto your trade-in paperwork, and you’re able to convert a headline-grabbing promo into an honest-to-gosh $0 flagship phone — chipped away at one credit at a time.
