How to cancel T-Mobile service

T-Mobile lets you cancel by phone, online, or in person at a store. The fastest route is calling their customer service line at 611 from your T-Mobile phone or 1-844-839-4534 from any phone — they can process the cancellation in one call and tell you what you owe. If you prefer not to call, you can visit a T-Mobile store with your account information, or log into your T-Mobile account online and look for the cancellation option in account settings, though online cancellation may redirect you to call anyway.

Before you cancel, know that T-Mobile will charge you an early termination fee if you are still under contract — typically $350 per line, though this amount can vary. You will also owe any remaining balance on a phone you financed through them, and your final bill will include charges through your cancellation date plus any prorated amounts. If you are past your contract end date or on a month-to-month plan, there is no termination fee.

Key Takeaways

  • Call 611 from your T-Mobile phone or 1-844-839-4534 from any other phone to cancel — this is the fastest way and takes one call.
  • You will owe an early termination fee of around $350 per line if you cancel before your contract ends, unless you are month-to-month.
  • Your final bill includes all charges through your cancellation date, any remaining phone balance, and prorated monthly fees.
  • You can also cancel in person at a T-Mobile store or through your online account, though phone cancellation is usually quickest.
  • Keep your account number and phone number handy when you call — the representative will ask for both.

What happens to your phone number

When you cancel, your phone number becomes inactive when ready. If you want to keep the number and move it to another carrier, you need to request a port authorization code (also called a PIN) before you cancel — T-Mobile will give you this code during the cancellation call. Write it down or have the representative email it to you.

Once you have the code, your new carrier can port the number over within a few hours to a few days. If you do not port the number before cancelling, T-Mobile holds it for a limited time (usually 30 days), but after that it goes back into circulation and you lose it permanently. If you decide later you want the number back, you cannot recover it.

Early termination fees and what you owe

An early termination fee applies only if you signed a contract with T-Mobile and are cancelling before the contract period ends. The fee is typically $350 per line, but T-Mobile may waive it in certain situations — for example, if you are moving to an area where T-Mobile does not have coverage, or if you are switching because of a service problem T-Mobile could not fix. Ask the representative about a waiver when you call; they cannot always grant one, but it is worth asking.

Beyond the termination fee, your final bill will include any charges through the day you cancel, any remaining balance on a financed phone, and a prorated amount for your monthly service if you cancel mid-cycle. For example, if your plan costs $60 a month and you cancel on the 15th of a 30-day month, you will owe about $30 for that partial month plus the termination fee and any other outstanding charges.

Cancelling a family plan or multiple lines

If you have a family plan with multiple lines, you can cancel the whole plan at once or remove individual lines. Cancelling the entire plan closes all lines and triggers early termination fees on any lines still under contract. Removing a single line from a family plan keeps the rest of the plan active and charges a termination fee only for the line you are removing.

When you call to cancel, tell the representative whether you want to cancel everything or just specific lines. If you are removing one line from a family plan, the remaining lines stay on the same plan and bill, and the person using the cancelled line will need a new carrier and phone number (unless you port the number first).

What to do after you cancel

After cancellation, your T-Mobile service stops working when ready — calls, texts, and data will not go through. If you have a new carrier lined up, make sure they have activated your service before you cancel T-Mobile, or you will have a gap with no phone service. The exception is if you are porting your number; in that case, the new carrier handles the timing and your number switches over automatically.

Keep your T-Mobile SIM card and phone in case you need to contact T-Mobile about your final bill or have questions. You do not need to return the SIM card or phone to T-Mobile — they are yours to keep. If T-Mobile sends you a final bill after cancellation, pay it on time to avoid collection action. If you dispute any charges on the final bill, contact T-Mobile customer service within 30 days of receiving it.

Cancelling without calling

If you want to avoid a phone call, you can visit a T-Mobile store in person with your account number and a photo ID. The store representative can process the cancellation, explain your final charges, and give you the port authorization code if you need it. This takes about 15 to 20 minutes and gives you a receipt for your records.

Some T-Mobile accounts allow cancellation through the T-Mobile app or website under account settings, but this option is not available on all accounts — if you do not see a cancellation option online, you will need to call or visit a store. Online cancellation, when available, usually sends you to a chat with a representative anyway, so calling directly is often faster.

Frequently Asked Questions

Can I cancel T-Mobile without paying an early termination fee?

You avoid the fee if your contract has ended or you are on a month-to-month plan. If you are still under contract, ask the representative about a waiver — they may grant one if you are moving to an area without T-Mobile coverage or if T-Mobile failed to fix a service problem. Otherwise, you will owe the fee.

What if I want to keep my phone number?

Ask for a port authorization code during your cancellation call and give it to your new carrier before your T-Mobile service ends. Your new carrier will port the number over, usually within a few hours to a few days. If you do not port it before cancelling, T-Mobile holds it for about 30 days, then releases it permanently.

Do I have to return my T-Mobile phone or SIM card?

No. T-Mobile does not require you to return the phone or SIM card — they are yours to keep. You can use the phone with another carrier if it is unlocked, or keep it as a backup device.

How long does it take to cancel?

A phone cancellation takes about 10 to 15 minutes. In-store cancellation takes 15 to 20 minutes. Online cancellation, if available on your account, may take longer because it often redirects you to a chat or call with a representative.

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

No refund — you pay a prorated amount for the days you used service in that billing cycle. If you cancel on the 15th of a 30-day month on a $60 plan, you owe about $30 for that partial month, plus any early termination fee and remaining phone balance.
