You can cancel T-Mobile by calling customer service, visiting a store, or using your online account

T-Mobile lets you cancel in three ways: by phone at 611 from your T-Mobile phone or 1-844-839-4534 from any phone, by visiting a T-Mobile store in person, or through your account on T-Mobile.com. The phone route is fastest if you know you want to cancel. In-store cancellation works if you have questions about early termination fees or want to discuss switching to another carrier. Online cancellation through your account dashboard is an option, though T-Mobile's website may prompt you to call instead.

Before you cancel, know that T-Mobile may charge an early termination fee if you're still under contract. This fee varies depending on how long you've had the account and what type of plan you're on. If you're month-to-month with no contract, there's no termination fee. Have your account number ready when you call — you'll find it on your bill or in the T-Mobile app.

Key Takeaways

  • Call 611 from your T-Mobile phone or 1-844-839-4534 from any phone to cancel, or visit a T-Mobile store in person.
  • Early termination fees apply only if you're still under a service contract; month-to-month accounts have no cancellation fee.
  • Have your account number ready before calling, and ask about the exact amount of any fees before you confirm the cancellation.
  • Your service will stop on the date T-Mobile processes the cancellation, which is usually within one to three business days.
  • Return any T-Mobile equipment like a router or device within 30 days to avoid additional charges.

Canceling by phone is the fastest method

Call 611 from your T-Mobile phone or 1-844-839-4534 from any other phone. You'll reach customer service, and they'll ask for your account number or the phone number associated with your account. Have your bill in front of you so you can provide this information quickly.

Tell the representative you want to cancel your account. They may ask why you're leaving or offer you a discount to stay — you can accept or decline. If you're under contract, they'll tell you the exact early termination fee before processing the cancellation. Ask them to confirm the cancellation date and whether any final charges will appear on your next bill.

The call usually takes 5 to 10 minutes. Write down the cancellation confirmation number the representative gives you — you'll need it if questions come up later about charges or service shutoff.

Canceling in person at a T-Mobile store

Visit any T-Mobile store with a photo ID and your account number or the phone number on the account. A store representative can cancel your account on the spot and answer questions about early termination fees or other charges specific to your situation.

In-person cancellation is useful if you want to discuss switching to another carrier or if you have multiple lines and want to cancel only some of them. The representative can walk you through what happens to each line and what you'll owe. Bring any T-Mobile equipment you own — a router, tablet, or other device — so you can return it immediately and avoid shipping it back later.

What happens to your service after cancellation

T-Mobile usually stops your service within one to three business days of processing the cancellation. You'll receive a final bill that includes any early termination fees, prorated charges for the days you used service in the final month, and any equipment fees if you didn't return devices.

If you're switching to another carrier, make sure you've ported your phone number before canceling — once T-Mobile closes your account, porting becomes more difficult. Ask your new carrier to start the porting process first, then cancel T-Mobile after the port is complete.

Your SIM card will stop working after the cancellation date. If you have a T-Mobile phone and want to use it with another carrier, you'll need a new SIM card from that carrier.

Early termination fees and what you might owe

Early termination fees apply only if you signed a service contract with T-Mobile. Month-to-month accounts have no cancellation fee. The fee amount depends on how much time is left on your contract — the more time remaining, the higher the fee. T-Mobile's representative will tell you the exact amount before you confirm the cancellation.

You may also owe a prorated amount for service used in the month you cancel. If you cancel on the 15th of the month, you'll pay for half the month's service. This charge appears on your final bill.

If you leased a phone from T-Mobile and haven't finished paying it off, you'll owe the remaining balance. Return the phone to a T-Mobile store or mail it back to avoid additional damage fees.

Returning T-Mobile equipment

Return any T-Mobile equipment — a home internet router, tablet, or other device — within 30 days of cancellation. You can return it to a T-Mobile store or mail it back using the prepaid shipping label T-Mobile provides. Keep the tracking number until T-Mobile confirms receipt.

If you don't return equipment within 30 days, T-Mobile will charge you for the device. These charges appear on your final bill or as a separate charge after cancellation. If you've already paid off a leased phone, you own it and don't need to return it.

Frequently Asked Questions

Will I be charged if I cancel in the middle of the month?

Yes, you'll pay a prorated amount for the days you used service in that month. If you cancel on the 10th of a 30-day month, you'll pay for 10 days of service. This charge appears on your final bill along with any early termination fees.

Can I cancel just one line if I have multiple lines on my account?

Yes. Call 611 or visit a store and tell the representative you want to cancel only one line, not the entire account. The other lines will stay active. You'll only pay an early termination fee on the line you're canceling if it's under contract.

What if I want to port my phone number to another carrier?

Ask your new carrier to start the porting process before you cancel T-Mobile. Once the port is complete, your number will work on the new carrier's network and your T-Mobile service will end automatically. If you cancel first, porting becomes harder and may take longer.

Do I have to return my T-Mobile phone?

Only if you're leasing it from T-Mobile. If you own the phone outright or have finished paying it off, you can keep it. If you're still paying off a leased phone, return it within 30 days or T-Mobile will charge you for it.

How long does it take for my service to actually stop?

T-Mobile usually stops service within one to three business days of processing the cancellation. Your SIM card will stop working after that date. If you need service to continue while you switch carriers, port your number first, then cancel.
