You can cancel att internet only by calling AT&T customer service directly at 800-288-2020. To cancel AT&T internet, the account owner must call AT&T customer service directly at 800-288-2020 for residential service; this is the only method that works, online and in-store cancellation are not available for standard AT&T internet plans. Before you dial, understand the complete financial picture: you have a 14-day grace period to cancel without an Early Termination Fee (ETF), but after that, a prorated ETF applies, your final bill is not prorated, and you must return leased equipment within 21 days to avoid non-return fees.
What you must know before you cancel AT&T internet
Before you call, confirm you are the account owner, AT&T will not discuss or process a cancellation with anyone else, even if you have the bill. If you are within 14 days of activation, you can cancel for any reason and avoid the ETF entirely; this is your only penalty-free window.
If you cancel after 14 days and have a term commitment, the ETF is prorated and decreases each month you keep service. The ETF will appear on your bill within three bill periods, so budget for it.
AT&T does not prorate your final bill, you will be charged for the full billing cycle even if you cancel mid-cycle. If you have a bundled subscription (internet + TV + phone), canceling just the internet may cause you to lose promotional discounts on the remaining services, so ask the retention agent to explain the impact before you commit. If you are trimming streaming costs too, you can similarly cancel Roku subscription channels without affecting your Roku account, and you can cancel a Kahoot subscription to stop recurring charges for that learning platform.
Support hours matter: AT&T internet customer service is open Monday to Friday 7am to 9pm Central Time and Saturday and Sunday 8am to 9pm Central Time. If you call outside these hours, your request will be handled on the next business day, so call during operating hours to get same-day processing.
The phone call: how to cancel AT&T internet step by step
Dial 800-288-2020 for residential internet or 800-321-2000 for AT&T Business internet or Business Fiber. Have your account number and PIN ready before you call, the representative will verify your identity with these, and missing them will delay the process.
- Call the correct number based on your service type (residential vs. business).
- When the automated system prompts you, say "cancel service" and then specify "Internet" to route to the right team.
- If the system does not route you correctly, ask to speak to the "retention" or "loyalty" department, this team has the authority to waive fees or offer retention deals.
- Provide your account number and PIN when asked, then state your cancellation date and reason.
- Confirm the exact cancellation date, ask for the final bill amount, and request a confirmation number before hanging up.
Expect the representative to try to keep you as a customer, they may offer discounts, data upgrades, or other incentives. You are not obligated to accept them, but if you are open to staying, this is the moment to negotiate. Note that online cancellation is generally not available for AT&T internet (except legacy DSL), and AT&T stores cannot process internet cancellations in person, so the phone call is your only path.
After you cancel: avoiding equipment fees and returning your gear
Once your service is cancelled, you have 21 days to return all leased AT&T equipment to avoid non-return fees. Do not delay, the clock starts on your cancellation date, not the day you receive the return kit.
- Gather your unpacked equipment: the Wi-Fi Gateway, All-Fi Hub, extenders, boosters, and any power cords (but do not remove wall-mounted fiber jacks or ONTs, those stay with the property).
- Take the equipment and your account number to a company-owned UPS Store or FedEx Office, AT&T stores will not accept returns, and drop boxes are not allowed.
- Tell the store representative you are returning AT&T equipment; they will scan, pack, and ship it for free.
- Keep the tracking receipt they give you, this is your proof of return and protects you from false non-return fees.
Non-return fees are steep: $150 for a Wi-Fi or All-Fi Gateway, $200 for an All-Fi Hub, and $65 for each Wi-Fi Extender or All-Fi Booster. If you miss the 21-day window, the fee is automatically refunded if you return the equipment within 6 months of termination, so even late is better than never.
Confirming your cancellation and planning your next connection
After you hang up, save the cancellation confirmation number in a safe place, you will need it if any billing disputes arise. Watch your next 1-3 bills for the ETF and any final charges; the ETF appears within three bill periods, and the final bill will include the full month's charge since AT&T does not prorate.
Check your final statement against the cancellation date and equipment return receipt. If you see any unexpected charges, call 800-288-2020 with your confirmation number and the tracking receipt from UPS or FedEx to dispute them.
