How to cancel T-Mobile

You can cancel T-Mobile by calling 611 from your T-Mobile phone or 1-844-839-4534 from any phone, or by visiting a T-Mobile store in person. The process takes about 15 minutes on the phone. You will need your account number (on your bill or in the T-Mobile app) and the phone number associated with your account. T-Mobile will ask why you are leaving and may offer you a discount to stay — you can accept or decline. Your service will end on the date you specify, and you will receive a final bill for any remaining balance.

You can also cancel through the T-Mobile app or website by logging into your account and selecting the cancellation option in Account Settings, though this route gives you fewer chances to ask questions or negotiate. Whichever method you choose, have your account information ready before you start.

Key Takeaways

  • Call 611 from your T-Mobile phone or 1-844-839-4534 from any phone to start the cancellation process.
  • Have your account number and the phone number on your account ready before you call.
  • You can choose the cancellation date — it does not have to be when ready.
  • If you are under a contract or have a device payment plan, you may owe an early termination fee or the remaining balance on your device.
  • Return any T-Mobile equipment (router, SIM card, or device) within 30 days to avoid additional charges.

What happens to your bill when you cancel

Your final bill will include charges through your cancellation date, plus any early termination fees if you are in a contract. If you have a device payment plan, you will owe the remaining balance on that device in full — this amount will appear on your final bill or be charged separately depending on your account type.

T-Mobile does not prorate charges, meaning you pay for the full month even if you cancel mid-month. If you have a balance on your account from a previous overpayment or credit, T-Mobile will explore that to your final bill first.

Early termination fees and device payoff amounts

Early termination fees explore only if you are in an active contract with T-Mobile. The fee amount depends on how much time remains on your contract — the more time left, the higher the fee. T-Mobile will tell you the exact amount when you call to cancel.

Device payment plans are separate from service contracts. If you financed a phone through T-Mobile and cancel service before the phone is paid off, you owe the remaining balance when ready. You can continue paying for the device after you cancel service, or you can pay it off in full at cancellation. Ask the representative which option works for your situation.

Returning equipment and avoiding extra charges

T-Mobile requires you to return any equipment they provided — this usually includes a SIM card, a home internet router if you had one, or a device if you financed it through them. You have 30 days from your cancellation date to return the equipment. Mail it to the address T-Mobile provides, or drop it off at a T-Mobile store.

If you do not return equipment within 30 days, T-Mobile will charge you a non-return fee, typically $150 to $350 depending on the item. Keep your tracking number if you mail the equipment back, in case there is a dispute about whether it arrived.

Cancelling in person at a T-Mobile store

Cancelling in person at a T-Mobile store takes longer than calling but lets you return equipment when ready and get a receipt. Bring your ID and account number. Not all stores handle cancellations, so call ahead to confirm your local store can process it.

In-person cancellation is useful if you have multiple devices to return or if you want to discuss your options face-to-face. The representative can still offer retention discounts, though the process is slower than a phone call.

What to do if you are locked into a contract

If you are in a contract and the early termination fee is high, ask T-Mobile about a contract buyout or transfer. Some carriers offer to pay early termination fees if you switch to them — this is called a "switch promotion" and is common among major carriers. You would need to move your number to that carrier, but your T-Mobile bill would be resolved.

Another option is to keep your T-Mobile service but downgrade to a cheaper plan to reduce your monthly cost while you wait out the contract. This does not cancel your service, but it lowers what you pay each month until the contract ends naturally.

Keeping your phone number after you cancel

You can transfer your T-Mobile phone number to another carrier or to a service like Google Voice. This is called number porting. When you cancel, tell the T-Mobile representative that you want to port your number out. T-Mobile will give you a PIN and account number that you need to provide to your new carrier.

Start the porting process with your new carrier before you cancel T-Mobile service, or port within 30 days of cancellation. If you wait longer than 30 days, T-Mobile may recycle your number and you will lose it permanently.

Frequently Asked Questions

Do I have to pay an early termination fee?

Only if you are in an active contract with T-Mobile. Device payment plans do not have early termination fees, but you owe the remaining balance on the device. Call 611 or 1-844-839-4534 and ask the representative whether your account has a contract and what the fee would be.

Can I cancel when ready or do I have to wait?

You can choose your cancellation date when you call. Some people cancel when ready, while others pick a date a few weeks out to give themselves time to switch to another carrier. T-Mobile will confirm the date you choose.

What if I want to cancel just one line on my account?

You can cancel a single line without cancelling your whole account. Call 611 or 1-844-839-4534 and tell the representative you want to remove one line. The remaining lines stay active and you will get a new bill reflecting only those lines.

Will T-Mobile offer me a discount to stay?

Possibly. When you call to cancel, T-Mobile usually offers a discount or promotional rate before processing the cancellation. You can accept the offer, ask for a better one, or decline and proceed with cancellation. There is no penalty for declining.

How long does it take to process a cancellation?

Your service ends on the date you specify. If you cancel on the 15th and choose the 30th as your end date, your service runs through the 30th and then stops. You will receive your final bill within one to two billing cycles after cancellation.
