To cancel an AT&T mobile line, call 800.331.0500 or dial 611 from your AT&T phone, then say "Cancel service" when prompted and provide your account number and phone number. This is the primary method to end your service and avoid unnecessary delays.
How to cancel an AT&T mobile line: The primary method
Calling AT&T directly is the most reliable way to cancel your wireless service. From any phone, dial 800.331.0500. If you are calling from an AT&T Wireless phone, you can dial 611 instead. When the automated system answers, choose your language (English or Spanish are available) and say "Cancel service" when prompted. You will then need to provide your AT&T Wireless account number or the phone number associated with the line you want to cancel. Have this information ready before you call to speed up the process.
Other ways to cancel
While calling is the most dependable method, you have a few other options. You can visit an AT&T Wireless store or kiosk in person to speak with a representative about canceling your line. Alternatively, you can use the online "Chat" option on AT&T's Contact Us page when it is available, though this feature is less reliable than a phone call. For wireless accounts in Illinois, Massachusetts, and New York only, if you ordered your service online, you may be able to cancel it directly at att.com/attaccount.
Fees and charges when you cancel
Be aware of the financial implications before you cancel. AT&T does not prorate charges for the final billing period; you are responsible for the entire period's charges even if you cancel mid-cycle. If your line has an installment plan for a device or accessories, the remaining unpaid balance is due immediately upon cancellation and will appear on your final bill. Early Termination Fees (ETFs) may apply if you signed a one- or two-year service commitment and cancel after the first 14 days for a personal account or after 30 days for a business account. For personal accounts, ETFs range from $58 to $325 depending on the device and when you cancel. For AT&T Business wireless accounts, cancellation fees can be up to $750 after the first 30 days. You will not have an ETF if you are on an installment plan, but you must still pay off the device. If you activate a device and cancel within 14 days, you avoid the ETF but must pay for service fees incurred and may face a restocking fee if you return the device. A restocking fee may apply if you return a device within the 14-day buyer's remorse period, though it may be waived for online orders picked up in-store. If you picked up an online order in the store, you should go to one of the stores to have the restocking fee waived, though fee waivers are subject to change. If you activated a device within the last 14 days and wish to cancel, you can find out how to return your device and cancel service on the AT&T Wireless Return Policy page.
Alternatives to cancellation
Instead of canceling outright, you can transfer billing responsibility for your line to another person's AT&T account. This allows someone else to take over the service and any associated device payments, which can be a better option if you are switching carriers but want to keep the line active.
Canceling for military deployment
If you are a U.S. military member or qualified dependent deploying under the Service members Civil Relief Act (SCRA), you have special protections. You can cancel or suspend your wireless service without paying Early Termination Fees. Eligible personnel can also hold their wireless number for up to 39 months if service is reactivated within that timeframe. To request cancellation, you will need the account name, account number, phone numbers to cancel, the date to cancel, the service member's full name, deployment date, your chosen option (cancel or cancel and hold), and deployment orders. If you cannot call, send an email with the completed forms to ATTMilitaryRequest@att.com with "Military cancel" in the subject line. Allow up to 24 hours for processing. If you cancel mid-cycle due to deployment, you will receive a partial-month charge and up to two more bills, and you are responsible for any existing balance and the final bill.
What to do before you call
Before you initiate cancellation, gather your wireless account number and the phone number(s) for the lines you want to cancel. If you plan to keep your phone number, port it out to your new carrier before canceling with AT&T; otherwise, you risk losing the number. Also, back up any data, photos, or files on your device, as AT&T reserves the right to delete any data, files, or other information associated with your account upon cancellation. Finally, note that canceling a line on a multi-line plan may cause you to lose any associated discounts for the remaining lines.
