Cancel a T-Mobile line by calling 611 from your T-Mobile phone or 1-844-839-4534 from any phone

T-Mobile will walk you through the cancellation over the phone. You do not need to visit a store or submit paperwork online. The call takes about 10 to 15 minutes. Have your account number ready — you can find it on your T-Mobile bill or in the T-Mobile app under Account.

If you have a contract or device payment plan, T-Mobile will tell you what you owe before the line closes. You pay this amount either when ready during the call or on your next bill. The line stops working within a few hours of cancellation, though you may receive one final bill in the mail.

If you want to keep your phone number, tell the representative before they process the cancellation. T-Mobile can port your number to another carrier, but you must start that transfer with the new carrier — T-Mobile cannot move it for you. The new carrier will guide you through the process and handle the port request with T-Mobile.

Key Takeaways

  • Call 611 from your T-Mobile phone or 1-844-839-4534 to cancel; no online form or store visit is required.
  • Have your account number ready and expect to hear what you owe if you have an active device payment plan or contract.
  • If you want to keep your phone number, tell T-Mobile during the call, then start the transfer process with your new carrier.
  • Your line stops working within hours, though a final bill may arrive in the mail weeks later.
  • You can cancel a single line on a family plan without closing the entire account.

What happens to your device payment plan

If you are paying for your phone through T-Mobile, canceling the line does not erase what you owe. T-Mobile will calculate the remaining balance on the device and tell you the amount during your cancellation call. You can pay it in full when ready, or T-Mobile will add it to your final bill.

If you own the phone outright — meaning you bought it without a payment plan or finished paying it off — you owe nothing for the device. You can take the phone to another carrier and use it there if it is unlocked. Ask T-Mobile to unlock it before you cancel if you plan to switch carriers.

Canceling one line on a family plan

If you have a family plan with multiple lines, you can cancel just one line without affecting the others. The remaining lines stay active and keep their numbers. T-Mobile will adjust your bill to remove the canceled line's charges.

When you call to cancel, tell the representative which line you want to close. They will confirm the phone number or account details for that specific line so there is no confusion. The rest of your family plan continues as normal.

Porting your number to another carrier

To move your T-Mobile number to a different carrier, you must start the request with the new carrier, not with T-Mobile. Call or visit the new carrier and tell them you want to port your number. They will ask for your T-Mobile account number and the phone number you want to move.

The new carrier sends a port request to T-Mobile. T-Mobile processes it within one to three business days. During this time, your T-Mobile line may stop working, or it may stay active until the port completes — this varies. Once the port finishes, your number rings on your new carrier's network and your T-Mobile service ends.

You can port your number before or after you cancel with T-Mobile. If you port first, your T-Mobile line closes automatically when the port completes. If you cancel first, you have 30 days to port the number before T-Mobile recycles it and assigns it to someone else.

What to do if you cannot reach T-Mobile by phone

If you have trouble reaching customer service by phone, you can cancel through the T-Mobile app or website. Open the T-Mobile app, go to Account, and look for the option to manage your lines. Select the line you want to cancel and follow the prompts. The app will show you any balance due and let you confirm the cancellation.

You can also visit a T-Mobile store in person. Bring your ID and account number. A representative can cancel your line on the spot, though you will still need to pay any balance due before leaving.

T-Mobile also offers chat support through their website. Go to t-mobile.com, click the chat icon, and explain that you want to cancel a line. A representative will walk you through the process in writing.

Understanding your final bill

After you cancel, T-Mobile sends a final bill that covers service through your cancellation date. This bill includes any prorated charges — if you cancel mid-month, you pay only for the days you used the service. It also includes any device balance you did not pay during the cancellation call.

The final bill arrives in the mail within two to three weeks. If you set up autopay, T-Mobile will charge your payment method automatically. If you did not set up autopay, you can pay the bill online, by phone, or by mail.

Frequently Asked Questions

Can I cancel my line without paying what I owe on my phone?

No. If you have an active device payment plan, you must pay the remaining balance to close the line. T-Mobile will not cancel the line until the balance is settled or you agree to pay it on your final bill. You can ask to pay in installments after cancellation, but T-Mobile will not waive the debt.

What if I cancel and then change my mind?

T-Mobile may reactivate your line within 30 days if you call back and ask. After 30 days, the line is closed permanently and your number may be reassigned. Reactivation is not may provide, so contact T-Mobile as soon as possible if you want to reverse the cancellation.

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

No refund. T-Mobile charges you only for the days you used the service through your cancellation date. If you paid for a full month and cancel partway through, that overpayment applies to your final bill or any balance you owe, but you do not receive cash back.

Can I cancel over email or through social media?

T-Mobile prefers phone, app, or in-person cancellations. You can try reaching T-Mobile through their social media accounts or email, but they will likely ask you to call or use the app instead. Phone is the fastest and most reliable method.

What happens to my T-Mobile voicemail and text messages after I cancel?

Your voicemail and text message history are deleted when your line closes. T-Mobile does not store these after cancellation. If you need to save important messages, take screenshots or write down the information before you cancel.
