Before you cancel phone service with AT&T: read this first
The critical port-out warning: never cancel before transferring your number
If you intend to keep your phone number and move it to a new provider, do not cancel your AT&T service. The correct sequence is to let your new carrier initiate the transfer; AT&T service will automatically cancel once the port is complete. Canceling first will likely result in losing your number permanently.
The Number Transfer PIN requirement
To port your number, you will need your AT&T account number and a Number Transfer PIN. This PIN is different from your account password, so request it from AT&T only when you are ready to begin the transfer process.
Check your AT&T contract, installment plan, and return window
Before calling, review your contract to understand potential costs. An Early Termination Fee (ETF) may apply if you cancel before your contract or service agreement ends. However, you can cancel service within 14 days of activation without being charged an ETF. If you have an installment plan for your device, the remaining unpaid balance on that plan is typically due immediately upon cancellation. AT&T generally does not prorate monthly service charges if you cancel mid-billing cycle, meaning you are responsible for charges through the end of your current billing cycle. If you are returning a device within the 14-day return period, a restocking fee of $55 may apply, though it might be waived for online orders returned in-store. Find your contract details in your online account under "Documents" or on your monthly bill.
How to contact AT&T customer service to cancel
The primary method to cancel is by calling AT&T customer service at 800-331-0500, or dial 611 from an AT&T wireless phone. Have your wireless account number and/or phone number(s) ready to proceed with cancellation. Alternative contact methods include online chat through the AT&T website, social media via Twitter or Facebook, or visiting an AT&T store in person. If you visit a store, bring your account information, ID, and any relevant documents. You can send a written request to cancel your phone service. Write a clear and concise letter stating your intention to cancel, including your account information and the reason for cancellation. Make sure to sign the letter and send it to the AT&T customer service address specified in your contract or on their website.
What to do with your device before returning it
Before returning a device, you must complete these mandatory steps: back up all personal data, disable security features like "Find My" apps, erase all personal data, remove the SIM card and memory card, and perform a factory reset. A restocking fee of $55 may apply for returns within the 14-day window, though it might be waived for online orders returned in-store.
How to port your number to a new carrier
The correct sequence is: your new carrier initiates the transfer, then AT&T service cancels automatically. Do not call AT&T to cancel separately, the port process handles the cancellation for you. This is part of canceling mobile orders and carrier service correctly.
