Official sources checked October 29, 2026. This guide explains U.S. consumer device promotions. Your signed installment agreement and the terms attached to your specific offer control your account.
Quick answer: Paying off your iPhone does not necessarily preserve its remaining promotional credits. Switching carriers can also end eligibility. Before acting, get two separate figures: the phone balance you owe and the future credits you would give up. Ask when any balance becomes payable.
A phone advertised as “free” through monthly bill credits can still carry an installment balance. A promotional credit reduces your bill only while you meet the offer’s conditions; it is not automatically a cash payment toward an early payoff.
Your phone balance and promotional credits are different
Start with your latest bill and installment agreement. Find the original financed amount, payments already made, remaining principal, monthly promotional credit and remaining credit months. Do not assume the advertised net monthly phone price is the remaining debt.
| Amount | What it means |
|---|---|
| Remaining device balance | The unpaid part of your financed phone. Ask for an actual payoff quote, including its effective date. |
| Unreceived promotional credits | Possible future savings. Losing them does not, by itself, mean that amount is added to your payoff bill. |
Taxes, service charges, separate discounts and any fees need their own review. Do not treat every service promotion, trade-in payment and device credit as the same benefit.
AT&T, T-Mobile and Verizon have different conditions
AT&T: read the exact promotion, especially its payoff wording
AT&T’s September 2026 iPhone announcement includes a separate online new-line credit offer in footnote 6. This example is distinct from ordinary device trade-in credits. Its terms say credits may stop if you upgrade or pay off early; canceling service stops credits and makes the remaining smartphone balance payable. To receive all credits, eligible service must continue for 36 months after credits start, and a financed new smartphone must remain on its installment agreement.
This is one published offer, not a universal rule for every AT&T trade-in promotion. Identify your own offer before relying on it. Ask AT&T to confirm in writing whether your credits survive payoff, a plan change or a number transfer.

T-Mobile: the promotion’s enrollment date matters
An Equipment Installment Plan (EIP) finances the device; Recurring Device Credits (RDC) are the promotional bill credits. T-Mobile’s offer FAQ says promotions enrolled on or after July 1, 2024 lose remaining monthly RDC after early payoff. Older promotions may continue as account-level credits, subject to their terms. Current support says future credits cannot be deducted from the EIP payoff. Verify your enrollment date and agreement rather than assuming older credits will continue.
Current support says cancellation loses remaining credits and makes remaining EIP payments due immediately. Some offer-FAQ wording advises contacting Care before cancellation about continued payments. Confirm your agreement’s payment timing and enrollment-specific rules before porting out.
T-Mobile promotional credits support · Official offer details and FAQ — checked October 29, 2026. The current offer-details page restricted direct access during our review. The official 2026 past-offer archive and FAQ was publicly retrievable and supplements the enrollment-date explanation; archived offers are not current recommendations. Official cancellation guidance still differs, so account-specific confirmation remains necessary.
Verizon: payoff ends monthly device credits; cancellation has exceptions
Verizon’s device-payment FAQ says monthly promotional device credits stop when you pay off early. Its deals FAQ also identifies cancellation, early upgrade and moving to a nonqualifying plan as reasons credits can end.
Cancellation generally makes the remaining device balance due. Verizon states a Missouri option to continue remaining balance payments over time. If you had an active Commitment Plan Discount with a term commitment, cancellation before that term ends may also trigger a separate Discount Chargeback. Verizon says this repays plan discounts actually received, capped at a maximum of a rolling six months. That cap applies to this plan-discount chargeback—not the device balance or lost future credits. Check whether that separate agreement applies to you.

Before changing anything: Save your offer terms, purchase date and promotional identifier. A carrier’s general FAQ helps explain the process but cannot establish the outcome for every account, retailer offer or older agreement.
A simple example: $600 owed is different from $480 in lost credits
Hypothetical illustration—not an advertised offer. Suppose a $900 phone is financed over 36 months at $25 per month. A promotion supplies $20 monthly credits, totaling $720 if all conditions are met for all 36 months.
Assume no down payment or interest, 12 installments paid, and 12 promotional credits received. After those 12 installment payments, the remaining device principal would be $600. You would have received $240 in credits, with $480 of possible credits still ahead.
- If payoff ends credits: the device payoff is $600 in this simplified example. The $480 is savings you will not receive; do not add it to the $600 as another automatic charge.
- Total device cost: after receiving only $240 of credits, the $900 phone effectively costs $660 before taxes and other charges. That is different from the amount due today.
- If you keep the qualifying arrangement: receiving every promised credit would reduce the device’s net cost to $180. Keeping service can have its own cost, so compare the whole remaining period.
This illustration excludes taxes, service, fees, payment adjustments and separate discount-repayment obligations. Use your carrier’s real payoff quote for a decision.
For the broader purchase decision, compare buying outright with carrier bill credits over 36 months, including service costs and an early-exit example.
A practical checklist before payoff or switching
- Locate the offer identifier, enrollment date, installment agreement and latest bill.
- Request the current device payoff, future credit total and exact date the balance would be due.
- Ask separately about early payoff, cancellation, plan changes, upgrades and line transfers. Save the answer and applicable terms.
- Check unlocking and compatibility before moving the phone. Paying a balance is not, on its own, proof that a device is ready for another network.
- Compare remaining service costs as well as device costs. Use our Carrier Plans guide and iPhone Deals guide to organize the comparison.
- If considering a switch reimbursement, verify that separate offer’s eligibility, required proof, claim deadline and payment method. Do not assume the new carrier automatically settles your old bill.
- Coordinate the number transfer with the receiving carrier before canceling the old line. Keep copies of bills and confirmation records.
Common questions
Does “no annual service contract” mean I owe nothing for the phone?
No. A service arrangement and a device installment agreement are different. Review the remaining device balance and promotional conditions even if service can be canceled.
Is early payoff the same as an early-upgrade program?
No. An upgrade program can have separate payment, return and device-condition requirements. Do not apply an ordinary payoff rule to an upgrade benefit without reading its terms.
Should I pay off before porting my number?
There is no safe universal order for every promotion. First verify the credit consequences, payment timing, unlock requirements and receiving carrier’s transfer instructions for your account.
How to use this guide
These are source-based explanations, not a review of your private carrier account or a guarantee that a credit will continue. Offer terms can change. Recheck the linked official terms before acting, and retain your original agreement for older promotions.
