To end T-Mobile service, the single most important rule is to port your phone number to your new carrier before you cancel anything, because porting out automatically cancels that specific line. This is the critical first step that preserves your number and avoids a disruption in service. If you are looking to completely close your account, you will need to follow the steps below for equipment returns and final billing, but the porting process is the only way to keep your number.
Before you end T-Mobile service: port your number first
If you wish to keep your phone number, you must transfer (port) it to your new carrier first; do not cancel your T-Mobile account before the transfer is complete, as porting out automatically cancels that specific line. Only the Primary Account Holder can generate a Port Out PIN or initiate a number transfer, so ensure you have your account credentials ready. To generate a Temporary Port Out PIN via the T-Mobile app, go to "Account," then "Profile Settings," then "Line Settings," and select "Request a transfer PIN." Alternatively, on the T-Mobile website, log in, select your name or "My Account," then "Profile," then "Line Settings," and select "Request a transfer PIN." You will need your T-Mobile account number, the Temporary Port Out PIN, your account PIN/Passcode, and your billing address to provide to your new carrier for a number transfer. Remember that T-Mobile transfer PINs are valid for 7 days, so coordinate the timing with your new carrier to ensure the port completes before it expires.
Check your equipment installment plan balance
Before you initiate the cancellation, review your Equipment Installment Plan (EIP) balance, as this determines your financial obligation. T-Mobile typically does not charge early termination fees (ETFs) for wireless service, but any remaining Equipment Installment Plan (EIP) balances become due immediately if the entire account is canceled. However, if you cancel a line but keep other active lines, device payments tied to the canceled line will continue to bill monthly, so you won't be hit with an immediate lump sum. This distinction is crucial when deciding whether to close the whole account or just a single line, as it directly impacts your immediate out-of-pocket costs.
How to contact T-Mobile to cancel your service
You can initiate the actual cancellation by contacting T-Mobile directly via phone, online chat, or by visiting a retail store in person. When you call or chat, you'll speak with a representative who can process the request, and you'll need to verify your identity as the Primary Account Holder. Note that cancellations are typically future-dated and take effect at the end of your current billing cycle, and you are responsible for all charges and usage through that period. This means you won't lose service immediately, so plan accordingly if you're switching carriers, you'll want your new service active before the T-Mobile line drops off.
Return your T-Mobile equipment
If you have leased devices or equipment from T-Mobile, you must return them to avoid non-return fees. This includes smartphones, tablets, routers, and any mesh Wi-Fi extenders that you didn't purchase outright. For T-Mobile Home Internet service, you must call customer care to cancel, and the gateway and any mesh Wi-Fi extender must be returned within 14 days (or 45 days according to another source) using a prepaid label to avoid a non-return fee of up to $370 plus tax. Before shipping, perform a factory reset on all devices and remove any SIM or SD cards to protect your personal data. Keep your shipping receipt or get a receipt from the T-Mobile store as proof of return, since this protects you if there's a dispute about whether the equipment was received.
Final steps: AutoPay, voicemail, and reactivation
Once your cancellation is processed, take a few final steps to avoid unwanted charges and data loss. It is recommended to turn off AutoPay before your final bill is processed to avoid automatic charges, as the system may otherwise attempt to collect the final balance from your linked payment method. Also be aware that voicemail messages and DIGITS call history are permanently deleted after cancellation and cannot be recovered, so save any important voicemails before the line is disconnected. If you think you might return to T-Mobile later, know that if you cancel service and later wish to reactivate, you can typically do so within 90 days without a new credit check or activation fee, though your previous number may not be available.
How to cancel T-Mobile home internet or prepaid service
The cancellation process differs for T-Mobile Home Internet and prepaid accounts compared to standard postpaid wireless lines. Prepaid accounts are simpler: they will automatically cancel after 120 days in "Not Paid" status if funds run out and Autopay is off, but to voluntarily cancel a prepaid account, call 1-877-778-2106. Additionally, be mindful that canceling lines may impact promotional credits, free or discounted line promotions, and multi-line discounts, so review your bill carefully before committing to the cancellation.
Frequently Asked Questions

Will I get a refund for unused service after canceling? No, T-Mobile does not prorate refunds for unused days in your billing cycle; you are responsible for charges through the end of the cycle, and any prepaid balance on a prepaid account is forfeited upon cancellation.
