T-Mobile Device Credits Stopped? How to Check Your Bills

Direct answer: A Recurring Device Credit that posted for months and then disappeared usually traces to one of the events T-Mobile lists as ending a promotion: the EIP was paid off or closed, the plan or service the promotion required was changed or cancelled, a JUMP! upgrade, a returned BOGO device, or a trade-in later judged ineligible. T-Mobile says it sends a message when an account change makes you ineligible. If no such change happened and no message arrived, compare the months before and after and ask T-Mobile, in writing, which account event removed the credit, inside its 60-day dispute window.

Quick checks

Count the RDC lines received. If the count equals the EIP term, the promotion finished.
Check for a T-Mobile message about an account change making you ineligible; T-Mobile says it sends one with a link to review the change.
Check whether the EIP was paid off, closed, or replaced by a JUMP! upgrade.
Check whether the plan changed, including a migration to a newer plan family, and compare the new plan with the promo code's requirement.
Check the newest bill for a Promo Reversal Charge, which signals a trade-in reversal rather than a plan issue.

What T-Mobile says ends a Recurring Device Credit

What T-Mobile says ends promotional credits

T-Mobile's promotional credits page lists what "will disqualify you from continuing to receive promotional credits": closing or cancelling the line or the Equipment Installment Plan tied to the promotion, not completing the EIP or e-signature in the promotional period, exchanging or returning a device outside the offer window, cancelling or changing the plan or service the promotion requires, a JUMP! upgrade from the device with the credit, returning one phone from a BOGO offer, failing to return a deferred trade-in in time, and a trade-in that arrives damaged. It adds: "If you pay off your EIP early, you'll forfeit the remainder of" the monthly RDC, and "If you cancel your T-Mobile service, you'll lose any remaining Recurring Device Credits." Checked September 2026.

Most of these leave a trace: a payoff receipt, an upgrade order, a plan change confirmation, or a trade-in assessment. The exception is a plan change made by another account manager or a plan migration, which is why the ineligibility message and the bill's plan name are the first two things to check.

The early-payoff rule

T-Mobile's page says that if you pay off the EIP early you forfeit the remaining monthly RDC, and that you cannot pay off an EIP by deducting the remaining credits from the balance; the full balance must be paid to close the plan. A payoff made to unlock the phone, to upgrade, or as part of an insurance replacement therefore ends the credit under the terms. If your credits stopped the month after a payoff, that is the explanation, and the only question is whether anything was promised in writing before the payoff.

Plan changes and plan compatibility

T-Mobile's disqualifying events include changing the plan or service the promotion requires. In August 2026 trade press reported a customer whose credits were removed with two months left after what T-Mobile described as a system audit finding the promotion incompatible with the plan, later reversed after escalation. That is a news report, not policy, but it illustrates the pattern: a removal tied to plan compatibility long after the credits started. If your removal cites the plan, compare the plan name on the bill with the promo code's stated requirement on T-Mobile's offer details page, and note whether the plan changed at all.

First: has the term ended?

RDC runs for the EIP term. If the EIP charge and the credit disappeared together and the count of credits matches the term, the promotion finished; the last credit can be a few cents different because of rounding. If the EIP charge continues and the credit does not, the promotion stopped early.

Stopped versus delayed

The two-cycle rule describes a credit that has not started. A credit that posted and then stopped was enrolled, so the earlier bills already prove the promo code, the amount, and the line. The review is about what ended it, not whether it existed.

Compare the months before and after

Synthetic exampleT-Mobile recurring device credit that stopped

A fictional $1,000 T-Mobile promotion posted the correct $41.67 Recurring Device Credit for two bills. After a plan change the next four bills show no RDC while the Equipment Installment Plan charge continues.

Bill	Expected	Found	Assessment
Jan 8, 2026	$41.67	$41.67	As expected
Feb 8, 2026	$41.67	$41.67	As expected
Mar 8, 2026	$41.67	$0.00	Credit not found
Apr 8, 2026	$41.67	$0.00	Credit not found
May 8, 2026	$41.67	$0.00	Credit not found
Jun 8, 2026	$41.67	$0.00	Credit not found

Result: Credit appears to have stopped
Expected monthly credit: $41.67
Credits possibly missing so far: $166.68
Remaining promotional value potentially at risk: $749.98 across 18 remaining credits

Two correct credits show the promotion was enrolled. Four zeros since the plan change mean $166.68 has not posted, and the remaining 18 credits ($749.98) depend on whether the new plan was actually ineligible for the promotion.

What to ask T-Mobile

Which account event removed the promotion, and on what date?
Is the promo code still attached to this EIP and line? If not, why?
If the plan is the reason: which plan is on the line now, when did it change, and is it excluded by the promo code's terms?
If no qualifying event happened, can the promotion be reinstated with the missed months caught up?
How many credits were applied and how many remain on the term?
Please provide a reference number and the answer in writing.

T-Mobile's 60-day written-dispute clause

For a stopped credit, the first bill without the credit is the one that ages out first. Send the written dispute early even while a support review is open. The dispute deadlines page compares the three carriers, and the FCC guide explains what an informal complaint does.

Where to find the documents in T-Life

T-Mobile's billing support page says that once you are logged in and on the Bill details screen, the Download PDF button gives you the summary or the detailed bill; the detailed bill is the one that shows per-line credits. T-Mobile's tutorials say up to 18 previous bills can be downloaded. The enrollment text T-Mobile sends when a promotion qualifies contains the promo code, which also appears on the bill and can be looked up on T-Mobile's promotional offer details page for the full terms.

How Phone Deal Audit helps

The free scan reads the bills before and after the stop and reports a stopped-credit pattern separately from a delayed one, with the months in question and, when the term is confirmed, the remaining promotional value that depends on the outcome. Nothing uploads.

Questions people ask

T-Mobile says a system audit removed my promotion. What does that mean?

T-Mobile does not publish a definition. In reported cases it described a review that found the promotion incompatible with the line's plan or eligibility. Ask which specific requirement the audit found unmet and on what date, and compare it with the promo code's published terms.

Will T-Mobile restore the missed months?

T-Mobile's pages describe catch-up credits for a late start but do not promise reinstatement after a removal. Reported cases include reinstatement after escalation. Ask for it explicitly and get the answer in writing.
