Cell Phone Early Termination Fees, Decoded: What You Actually Owe

The text says you can switch carriers anytime. The next bill says you owe $487. Both are true.

A cell phone early termination fee in 2026 isn't really a termination fee anymore. It's the unpaid balance on a device loan, plus whatever credits the carrier promised to spread across 36 months but stopped giving you the day you left. The label changed. The amount didn't.

This is what carriers actually charge when you leave early, why the "no contract" pitch is still a contract, and how to switch without paying twice.

TL;DR

• Most major carriers killed the traditional two-year contract years ago. They replaced it with a 24- or 36-month device installment loan that has the same lock-in effect.
• AT&T still has a classic ETF on a few legacy plans. Verizon and T-Mobile collect through the device loan and forfeited promotional credits.
• Carriers that offer to "pay your ETF" usually pay it as a virtual prepaid card after you trade in your phone, port your number, and stay on their network for several months.
• The FCC requires your carrier to unlock your phone after the device loan is paid off or the ETF is paid. Don't leave without unlocking.

The contract didn't disappear, it just changed shape

For about a decade, the wireless industry has been telling you there's no contract. Technically true, on the service side. The agreement to pay for service month-to-month is cancellable at will.

The agreement to pay for the phone is not.

When you walked out of the store with the new model, you didn't buy it. You financed it on a 24- or 36-month installment plan, and the carrier subsidized the price by giving you monthly bill credits that only continue while you stay on a qualifying plan. Leave early and two things happen: the unpaid device balance becomes due, and the future bill credits stop.

Verizon's customer agreement spells it out:

If you cancel a line of Service, or if Service is canceled for any
reason before the end of your device payment plan, the unpaid balance
of the retail price of the device will become immediately due and
payable. Promotional bill credits will end and will not be refunded.

That paragraph replaced the old "$350 ETF, prorated by months remaining" clause. It's worse. The unpaid balance plus forfeited credits on a $1,200 phone bought twelve months in can still be $700 or more.

What you actually owe, by carrier

The numbers change every year, but the structure is consistent. Here's the 2026 baseline.

AT&T still has a true early termination fee on a small set of legacy plans and connected-device contracts. Smartphones: $325, reduced by $10 per full month of service completed. Basic phones, tablets, and connected devices: $150, reduced by $4 per month. Most consumer postpaid plans no longer have this fee, but installment-plan device balances still apply.

Verizon has no ETF on most current plans. Device payment plan balances are due on cancellation, and any active promotional credits stop and are not refunded. Those credits are the "$1,000 off with trade-in over 36 months" deals you signed up for at the store.

T-Mobile has no service ETFs at all. Device installment balances are due in full on cancellation. Promotional credits stop the same way.

The "no contract" carriers, meaning prepaid plans and MVNOs like Mint or US Mobile, genuinely have no termination fee. There's no service contract and no device subsidy to claw back.

The trap to spot: the bigger your trade-in or promotional credit, the more you owe if you leave early. A $1,000-off deal spread over 36 months is $28/month in credits you forfeit. Leave at month 6 and you walk away from $840 in future credits, plus you owe the device balance. The early termination fee calculator totals the device payoff, the forfeited credits, and the time-of-service prorate so the number is honest before you port out.

"We'll pay your ETF" is not what it sounds like

Every major carrier runs a switching offer that promises to cover whatever your old carrier charges to leave. The marketing implies cash. The fine print is different.

T-Mobile's typical version requires you to:

1. Submit a final bill from your old carrier within 30 days of porting your number, showing the ETF or device balance.
2. Trade in your old phone in good working condition with the screen intact, up to the trade-in value cap.
3. Stay active on a qualifying T-Mobile postpaid plan for several months.
4. Receive the reimbursement as a virtual prepaid Mastercard, not a service credit and not cash.

Verizon and AT&T run similar programs with similar conditions. The offers are real and people do collect, but the friction is real too. Cap amounts are common. Reimbursement timelines run two to three billing cycles. If you cancel the new plan early, the offer is voided.

Treat the switch-and-get-paid offer as a discount on switching, not as a free pass.

The unlock requirement most people don't know about

Here's the rule the FCC made carriers agree to in 2024 and that takes meaningful effect in 2026.

Once your device installment plan is paid in full, your early termination fee is paid, or you've completed your prepaid usage requirement, your carrier must unlock your phone within two business days of the request. Automatically, with no extra fee.

You don't need to threaten anyone. You don't need to argue. You don't need to switch first.

What this means in practice: the day your last device payment posts, file the unlock request. Verify the unlock by inserting another carrier's SIM. Don't trust the carrier's claim that "it'll unlock automatically." Confirm it. A locked phone is worth less on the resale market and useless on most international networks.

When the carrier changes the contract on you

Most wireless customer agreements include a clause like this:

We may, at any time and in our sole discretion, change the terms of
this Agreement, including any prices, fees, or other charges. We will
provide you with notice of material changes. Your continued use of the
Service following such notice constitutes your acceptance of the
revised terms.

That's a unilateral modification clause, and it's standard.

The catch the carriers don't advertise: when they invoke it to raise prices or change material terms, you generally have a window of 14 to 60 days to cancel the affected line without an ETF. The change-of-terms notice itself triggers the right. The notice arrives buried in your bill or as a "Service Notice" email. Read those. The same logic applies when a carrier merges, sunsets a network band, or modifies plan limits in a way that genuinely degrades the service you bought.

This is a close cousin of the unilateral terms-of-service change problem that runs through every consumer contract.

The chargeback path, when the bill is wrong

If you cancel and get billed for an ETF you don't owe, or charged for service after you ported out, the dispute path runs in this order.

First, dispute it with the carrier in writing. Email or chat is fine, but make sure there's a written record. Cite the date you ported out, the device-loan payoff confirmation, and the specific charge.

Second, if the carrier won't budge, dispute the charge with your credit card or debit card issuer within 60 days of the statement. Federal law gives you that window for billing errors. The card issuer must investigate.

Third, file a complaint with the FCC at fcc.gov/complaints. The carrier has 30 days to respond formally, and they often quietly fix the bill at this stage to avoid the open complaint.

A chargeback or stop-payment doesn't end the underlying device loan. The unpaid balance is still owed. But it does stop the carrier from collecting a fee you can prove you don't owe.

How to leave cleanly

Five steps, in order:

1. Pay off the device balance through the carrier's app, or confirm what's left if you can't pay it off.
2. Request the unlock. Confirm it works with another SIM.
3. Port your number to the new carrier before canceling the old plan. If you cancel first, you lose the number.
4. Keep the final bill, the device-loan payoff confirmation, and any "we'll pay your ETF" submission paperwork for at least a year.
5. If you took a switching offer, set a calendar reminder for the date the prepaid card should arrive. Follow up if it doesn't.

The contract you didn't notice you signed

A cell phone early termination fee is the canonical version of the hidden default shape: the agreement is structured so the burden of leaving falls on you, not on them. The device installment loan is a contract by another name, and the auto-renewal logic that locks in service plans is the same logic that turns a 36-month device loan into a 36-month commitment.
