The fastest way to cancel T-Mobile is to call 611 from your T-Mobile phone or 1-844-839-4534 from any phone, tell them you want to cancel, and ask them to email you a confirmation.

T-Mobile does not require you to visit a store or mail anything back to cancel service. You can do it entirely by phone. The call usually takes 10 to 15 minutes. They will ask why you are leaving and may offer you a discount to stay — you can accept or decline. At the end, they will send you a confirmation email with your cancellation date and any final charges.

If you have an active contract or device payment plan, cancellation may trigger an early termination fee. T-Mobile charges this fee only if you are still paying off a phone through their installment program or if you signed a service agreement. The fee amount depends on how much of the device payment remains. You can ask the representative on the phone what your fee will be before you confirm the cancellation.

Key Takeaways

  • Call 611 from your T-Mobile phone or 1-844-839-4534 to start the cancellation process, and ask for a confirmation email when you are done.
  • T-Mobile will charge an early termination fee only if you are still paying off a phone through their installment plan or have an active service contract.
  • Your service will stop on the date T-Mobile confirms in your cancellation email, usually within a few days of your call.
  • You do not need to return your phone or SIM card, but you should remove your SIM card if you plan to use the phone on another network.
  • Check your final bill carefully — it will include prorated charges for the days you used service in your last month.

What happens to your phone number after cancellation

T-Mobile will release your phone number 30 days after your service ends. During those 30 days, you can port the number to another carrier if you want to keep it. After 30 days, T-Mobile recycles the number and you lose it permanently.

To port your number to a new carrier, contact that carrier and tell them you want to transfer your T-Mobile number. They will ask for your account number and PIN, which you can find on your T-Mobile bill or by logging into your account online. The port usually takes one to three business days. Do this before your 30-day window closes, or you will have to get a new number with your new carrier.

Early termination fees and what they cover

An early termination fee applies only if you are paying for a phone through T-Mobile's Equipment Installment Plan (EIP). The fee is the remaining balance on that phone. For example, if you owe $300 on a phone and you cancel, you will owe $300 as an early termination fee.

If you own your phone outright or bought it elsewhere, there is no early termination fee. If you have a service contract (which is rare with T-Mobile now), there may be a separate fee, but T-Mobile will tell you the exact amount when you call to cancel.

You can pay the early termination fee with the same payment method you use for your monthly bill. T-Mobile will add it to your final bill, or you can pay it immediately over the phone during your cancellation call.

Your final bill and what to expect

Your final bill will arrive within one to two weeks after your cancellation date. It will include any charges for the days you used service in your last month (prorated charges), any early termination fees, and any other outstanding balances on your account.

If you have a credit balance on your account — for example, from overpaying or from a promotional credit — T-Mobile will refund it. Refunds typically take five to seven business days to appear in your bank account or on your credit card, depending on your bank.

Review your final bill carefully. If you see charges you do not recognize or believe are incorrect, call T-Mobile customer service at 1-844-839-4534 and ask them to explain the charges. You have the right to dispute any charge within a reasonable time frame.

Canceling a family plan or account with multiple lines

If you have a family plan with multiple phone lines, you can cancel the entire account or just your individual line. When you call 611 or 1-844-839-4534, tell the representative whether you want to cancel your line only or the whole account.

If you cancel only your line, the account stays active for the other lines and they will continue to be billed. If you cancel the entire account, all lines will be disconnected. Each line that has an active device payment plan will incur its own early termination fee.

If you want to remove one line from a family plan but keep the others active, T-Mobile can do this during the same call. The remaining lines will stay on the same billing cycle and plan.

What to do with your T-Mobile phone after cancellation

You own your phone after you cancel service — T-Mobile does not require you to return it. If you want to use the phone on another carrier, remove the SIM card and insert a new one from your new carrier. The phone will work on any network that uses the same technology (most carriers use the same standard now).

If you want to sell or give away your phone, make sure to remove your SIM card and perform a factory reset to erase your personal data. You can also trade in your phone to T-Mobile or to another retailer for credit toward a new device, though this usually happens before cancellation.

If your phone is damaged or you do not want to keep it, you can recycle it at most electronics retailers or through T-Mobile's trade-in program.

Canceling T-Mobile without calling

You can also cancel through T-Mobile's website or mobile app if you prefer not to call. Log into your account, go to the Account or Settings section, and look for the option to cancel service or close your account. The process is similar to calling — you will be asked why you are leaving and shown any fees that apply.

Some T-Mobile stores will also cancel your service in person, though this is less common. Call ahead to confirm your local store offers this service. Canceling by phone remains the fastest and most straightforward method.

Frequently Asked Questions

Do I have to pay an early termination fee if I switch to another carrier?

You only pay an early termination fee if you are still paying off a phone through T-Mobile's installment plan. If you own your phone or bought it elsewhere, there is no fee. The fee is the remaining balance on the phone, not a separate penalty.

Can I cancel my T-Mobile service if I have an unpaid balance?

Yes, you can cancel even with an unpaid balance. T-Mobile will add any outstanding charges to your final bill. You will need to pay the full amount — including the unpaid balance, any early termination fee, and prorated charges — before T-Mobile considers the account closed.

How long does it take for my T-Mobile service to actually stop after I call to cancel?

T-Mobile usually stops your service within one to three business days of your cancellation call. The exact date will be in your confirmation email. Your phone will stop working on that date, so plan accordingly if you need time to transfer your number or data to a new carrier.

What if I change my mind after canceling?

If you cancel and then change your mind, call T-Mobile immediately. If your service has not yet been disconnected, they can usually reverse the cancellation. Once your service is disconnected, you will need to reactivate your account, which may require a new contract or setup fee.

Will I get a refund if I cancel mid-month?

No, you will not get a refund for unused days. T-Mobile charges you through your cancellation date. However, if you have a credit balance on your account from overpaying or promotional credits, T-Mobile will refund that amount.
