  • AT&T Customer Service, Internet, Billing & Home Phone

AT&T customers may need help with an internet outage, slow Wi-Fi, unexpected bill increase, installation appointment, equipment return, home-phone repair, U-verse TV account, moving service, fraud, cancellation, or inaccessible myAT&T account.

This is the main AT&T customer-service guide for AT&T Internet, Fiber, Internet Air, home phone, Digital Phone, legacy U-verse TV, billing, and general account support. For mobile plans, devices, trade-ins, prepaid service, roaming, or wireless promotions, see our AT&T Wireless customer service guide.

AT&T contact information reviewed and updated in June 2026.

AT&T customer service for internet, billing, and home phone support
AT&T internet, billing, home-phone, outage, and account-support information.

How To Contact AT&T Customer Service

Important: The corporate main telephone number is not the normal route for billing, internet repairs, wireless support, or account changes. Start with the department responsible for the service involved.

AT&T does not prominently advertise one general customer-service email address. Customers are generally directed to telephone support, secure chat, myAT&T, or a service-specific online form.

AT&T Customer Service Hours

AT&T currently lists its main internet and home-phone support line, 1-800-288-2020, as available 24 hours a day, seven days a week.

Specialized departments may follow different schedules. Accessibility, sales, cancellation, landline repair, business, and other teams may not have the same hours as general technical support.

Choose the Correct AT&T Support Department

  • AT&T Fiber, Internet, Internet Air, Wi-Fi, billing, or installation: Call 1-800-288-2020.
  • Traditional landline or AT&T Digital Phone: Call 1-800-288-2020.
  • U-verse TV: Call 1-800-288-2020 or select U-verse TV on AT&T’s contact page.
  • Wireless phone, tablet, smartwatch, trade-in, or mobile plan: Call 1-800-331-0500, dial 611, or use our AT&T Wireless guide.
  • Unauthorized internet or home-phone account: Call 1-877-379-2319.
  • DIRECTV: Use DIRECTV’s separate support system.
  • DISH Network: Contact DISH directly. DISH is not an AT&T customer-service department.
  • Small or enterprise business service: Use AT&T Business Support.

Information To Gather Before Contacting AT&T

  • The AT&T account number
  • The account owner’s name
  • The account passcode or approved verification method
  • The service address and billing ZIP code
  • The type of service involved
  • The date the problem began
  • The current and previous AT&T bills
  • The gateway, modem, router, or phone model
  • The serial number of equipment involved
  • The exact error message or status-light pattern
  • Installation, repair, or technician appointment information
  • Previous case, repair, or order numbers
  • Photos or screenshots of equipment, charges, offers, or errors
  • The specific resolution being requested

Do not post account passcodes, Social Security numbers, complete payment-card numbers, complete account numbers, or other sensitive information in a public review.

Common Reasons Customers Contact AT&T

  • Internet or fiber outage
  • Slow or unreliable Wi-Fi
  • Gateway or modem not working
  • Installation appointment missed or delayed
  • Unexpected bill increase
  • Promotion or credit missing
  • AutoPay discount not appearing
  • Payment applied to the wrong account
  • Moving internet service
  • Canceling AT&T Internet
  • Returning a Wi-Fi gateway or All-Fi Hub
  • Equipment-return fee
  • Home-phone outage or repair
  • U-verse TV billing or cancellation
  • Unable to sign in to myAT&T
  • AT&T Mail password or access problem
  • Unauthorized account or account change
  • Unresolved billing or service complaint

AT&T Billing and Unexpected Charges

An AT&T bill may change because of:

  • A promotional rate ending
  • A plan or speed change
  • Partial-month charges or credits
  • Equipment or extender charges
  • Installation or technician fees
  • Late-payment fees
  • Taxes and government surcharges
  • U-verse TV programming changes
  • Home-phone features
  • An AutoPay or paperless-billing discount ending
  • A service being added to or removed from a bundle

How To Review a Higher AT&T Bill

  1. Download the current and previous bills from myAT&T.
  2. Compare each service and charge rather than only comparing the total.
  3. Look for a promotion-ending notice.
  4. Check for partial-month charges or credits.
  5. Review equipment, installation, and add-on fees.
  6. Confirm that AutoPay and paperless billing remain active.
  7. Check whether a discount requires a particular payment method.
  8. Contact AT&T and ask the representative to explain each disputed line.
  9. Request a case number for any promised correction or credit.

AT&T states that some discounts and credits can take more than one bill period to appear. Ask the representative which bill should contain the adjustment and continue checking until it is posted.

AT&T Payment Problems

Customers may contact AT&T because a payment was duplicated, applied to the wrong account, reversed, returned, or not reflected on the bill.

Before Reporting an AT&T Payment Problem

  • Check whether the transaction is pending or completed.
  • Confirm the account number used for the payment.
  • Review the payment date and amount.
  • Check whether AutoPay also processed a payment.
  • Save the bank or card statement.
  • Locate the AT&T payment confirmation.
  • Confirm whether multiple AT&T accounts use the same payment method.

AT&T provides an online payment-assistance process for customers who need to document a disputed transaction. Be prepared to provide the payment date, amount, account number, and supporting statement information.

AT&T Internet or Fiber Outage

Before resetting equipment or scheduling a technician, determine whether AT&T has reported an outage in the area.

How To Check an AT&T Outage

  1. Open the AT&T outage checker.
  2. Sign in for information specific to the service address.
  3. Review the estimated restoration information.
  4. Sign up for outage alerts when available.
  5. Save screenshots of the outage notice and restoration estimate.

If AT&T does not report an outage, test whether the problem affects every device or only one computer, television, phone, or room.

Basic AT&T Internet Troubleshooting

  1. Check the gateway’s power, broadband, and service lights.
  2. Confirm that cables are firmly connected.
  3. Unplug the gateway or modem from power.
  4. Wait at least 20 seconds.
  5. Reconnect the power and allow the gateway to restart fully.
  6. Test a wired Ethernet connection when possible.
  7. Test more than one device.
  8. Check the AT&T outage page.
  9. Use Smart Home Manager to run diagnostics.
  10. Record the exact error message or light pattern.

A normal restart is different from a factory reset. A factory reset can erase customized Wi-Fi names, passwords, and other settings. Do not hold the reset button unless the troubleshooting instructions specifically call for a full reset.

Slow AT&T Internet or Wi-Fi

Slow service can involve the AT&T connection, Wi-Fi coverage, gateway placement, a single device, or heavy network use inside the home.

How To Narrow Down a Speed Problem

  • Run a wired speed test near the gateway.
  • Compare wired and wireless results.
  • Test several devices.
  • Test at different times of day.
  • Move closer to the Wi-Fi gateway.
  • Restart the gateway.
  • Disconnect unused devices temporarily.
  • Check whether cloud backups, security cameras, or game downloads are using bandwidth.
  • Confirm that the gateway is in an open, central location.
  • Use Smart Home Manager to review connected devices and Wi-Fi coverage.

When contacting AT&T, provide both wired and wireless test results. A good wired speed with poor Wi-Fi performance may point to coverage or equipment placement rather than a problem with the incoming internet connection.

AT&T Smart Home Manager

AT&T Smart Home Manager can help internet customers:

  • Check network status
  • Restart the Wi-Fi gateway
  • View connected devices
  • Change the Wi-Fi name and password
  • Run diagnostics
  • Test internet speed
  • Manage parental controls
  • Review Wi-Fi coverage
  • Schedule or manage a repair appointment

Customers who cannot access Smart Home Manager should confirm that they are signing in with the AT&T ID connected to the internet account.

AT&T Installation and Technician Appointments

Customers may contact AT&T about a delayed installation, missed appointment, incomplete activation, technician charge, or service that stopped working shortly after installation.

Before Contacting AT&T About an Appointment

  • Locate the order or appointment number.
  • Confirm the service address.
  • Check email and text messages for schedule changes.
  • Use the order and appointment tracker.
  • Record the promised arrival window.
  • Photograph incomplete or damaged installation work.
  • Write down any temporary service or equipment provided.

If AT&T misses an appointment or the technician leaves without restoring service, ask whether a new appointment has actually been scheduled and request its confirmation number.

Moving AT&T Internet Service

AT&T provides a moving process that checks whether service is available at the new address and whether the customer can keep the existing plan.

Steps To Transfer AT&T Service

  1. Check AT&T availability at the new address.
  2. Review the internet technology and speeds offered there.
  3. Select a disconnect date for the old address.
  4. Select an installation or activation date for the new address.
  5. Confirm whether the existing gateway should be moved or returned.
  6. Ask whether promotional pricing or discounts will change.
  7. Save the move-order number and appointment details.

AT&T internet service is tied to the account owner and generally cannot simply be transferred to a new resident. The new resident usually needs to create a separate account.

Canceling AT&T Internet or Home Service

AT&T directs residential internet customers to call 1-800-288-2020 to cancel service.

Before Canceling AT&T

  • Review the billing-cycle ending date.
  • Check for an installment agreement or early-termination obligation.
  • Determine whether removing one service changes bundle pricing.
  • Download recent bills and account records.
  • Confirm the final service date.
  • Ask which equipment must be returned.
  • Request a cancellation confirmation number.
  • Confirm how the final bill will be delivered.

AT&T states that internet service may remain active until the end of the billing period. Ask the representative to explain whether the final bill will be prorated and which charges will continue through the scheduled cancellation date.

Returning AT&T Internet Equipment

Customers may need to return an AT&T Wi-Fi gateway, modem, All-Fi Hub, extender, or power supply after canceling service, changing equipment, or receiving a replacement.

AT&T currently states that undamaged equipment should generally be returned within 21 days of the service-change or disconnect date to avoid a non-return fee.

Equipment-Return Tips

  • Confirm exactly which equipment must be returned.
  • Record each model and serial number.
  • Photograph the equipment before returning it.
  • Include required power supplies and accessories.
  • Use the AT&T-approved return method.
  • Keep the carrier receipt and tracking information.
  • Check the final bill for an equipment charge.
  • Keep the receipt until AT&T confirms the return was processed.

Do not assume that every cable, extender, mount, or accessory must be returned. AT&T’s return requirements differ by service and equipment model.

AT&T Home Phone and Landline Repair

Call 1-800-288-2020 to report an AT&T landline or Digital Phone problem.

Before Reporting a Home-Phone Outage

  • Check whether every telephone in the home is affected.
  • Test a corded phone when available.
  • Disconnect answering machines, fax machines, and other equipment temporarily.
  • Check whether AT&T internet is also unavailable.
  • Record whether the problem involves no dial tone, static, dropped calls, or inability to receive calls.
  • Determine whether nearby AT&T customers are also affected.
  • Check for visible damage to an outside line or utility box.

Do not touch a downed or damaged communications line. Report the location to AT&T and keep people away from any line that could also involve electrical equipment.

U-verse TV and DIRECTV Support

AT&T’s current contact page lists U-verse TV and DIRECTV as separate support selections.

  • Existing U-verse TV customers: Call 1-800-288-2020 or select U-verse TV through AT&T Support.
  • DIRECTV customers: Use DIRECTV’s website, app, telephone support, or account tools.
  • DISH customers: Contact DISH directly rather than AT&T.

Do not use outdated “AT&T and DIRECTV” or “AT&T and DISH” numbers unless the number appears on a current bill or official support page for the service involved.

AT&T Mail and Email Login Problems

AT&T Mail users may need help with a forgotten password, locked account, missing email, suspicious forwarding rule, or email program that no longer connects.

Steps To Secure an AT&T Email Account

  1. Reset the AT&T password.
  2. Review recovery email addresses and phone numbers.
  3. Check forwarding settings and filters.
  4. Review sent messages for unfamiliar activity.
  5. Remove unrecognized third-party email applications.
  6. Use a secure mail key when required by an older email program.
  7. Change passwords on other accounts that used the same password.

Be cautious of messages stating that an AT&T mailbox will be closed unless the customer immediately verifies a password or payment method.

Unauthorized AT&T Internet or Home-Phone Accounts

Call AT&T’s Voice and Internet Fraud Department at 1-877-379-2319 if someone opened an unauthorized internet or phone account or made an unauthorized change.

Information To Gather for an AT&T Fraud Report

  • The unauthorized account or service address
  • The date the account was discovered
  • Collection letters or credit-report entries
  • AT&T bills or order confirmations
  • An identity-theft report when applicable
  • A police-report number when available
  • Copies of identification requested through AT&T’s secure process
  • Previous fraud case numbers

Do not email identification documents or Social Security numbers to an address that has not been verified through AT&T’s official fraud process.

AT&T Phishing, Fake Support, and Payment Scams

Scammers may impersonate AT&T and claim that:

  • The internet will be disconnected immediately
  • A bill is overdue
  • The customer qualifies for a large discount
  • The router has been hacked
  • A refund is waiting
  • A technician needs remote access to a computer
  • Payment must be made by gift card or cryptocurrency

Do not provide an AT&T password, account passcode, one-time verification code, complete card number, or remote access to an unexpected caller.

End the communication and contact AT&T through its official website, app, bill, or verified telephone number.

How To Escalate an Unresolved AT&T Complaint

  1. Start with the correct department. Use internet, home phone, wireless, fraud, U-verse, or business support as appropriate.
  2. Request a case number. Record the date, time, representative, and promised action.
  3. Ask for supervisor review. Clearly state the problem, evidence, and requested resolution.
  4. Use secure chat. Save the transcript before closing the conversation.
  5. Document promised credits. Record the amount and expected billing statement.
  6. Track repair appointments. Save appointment confirmations and technician notes.
  7. Keep equipment-return proof. Retain tracking and carrier receipts.
  8. Submit a formal Notice of Dispute when appropriate. Use AT&T’s official process only after ordinary customer-service efforts have failed.
  9. Consider an outside complaint. Depending on the problem, options may include the FCC, a state consumer-protection agency, attorney general, or payment-card issuer.

AT&T describes a Notice of Dispute as a formal escalation to its Legal Department, not simply another customer-service complaint. AT&T states that its Legal Department has 60 days after receiving a complete notice to investigate and attempt a resolution.

AT&T Customer Reviews and Complaint Sentiment

At the time this page was updated, the CustomerServiceNumbers.com rating module displayed an AT&T rating of 2.0 out of 5 stars based on four reviews.

The four visible reviews were submitted in 2016 and 2018. They discuss:

  • A business customer reporting two days without telephone service
  • Repeated problems with replacement wireless phones
  • Frustration with receiving refurbished replacement devices
  • A dispute over the remaining installment balance on an unused mobile phone

Most of these older submissions involve AT&T Wireless devices and policies rather than current AT&T internet or home-phone support. Wireless customers should also review and submit feedback on the dedicated AT&T Wireless page.

The 2.0 rating is based on a very small and older sample. It should not be interpreted as a current rating of every AT&T service, technician, store, network, or customer-service department.

What To Include in an AT&T Review

  • The AT&T service involved
  • Whether the issue involved internet, fiber, billing, home phone, U-verse, or wireless
  • The support route used
  • Whether AT&T opened a case or repair ticket
  • How long it took to receive assistance
  • Whether a technician was required
  • Whether a promised credit appeared
  • Whether equipment was returned successfully
  • Whether the issue was ultimately resolved

What To Expect When Contacting AT&T

  • The automated system may ask for the account or telephone number.
  • The representative may require the account passcode or another verification method.
  • Internet, wireless, home phone, TV, business, and fraud issues may be handled by different departments.
  • AT&T may run remote equipment diagnostics.
  • Technical support may ask the customer to restart the gateway.
  • A technician appointment may be required.
  • A promised credit may not appear until a later billing statement.
  • Cancellation may affect bundle pricing and discounts.
  • Returned equipment may take time to be removed from the account.

AT&T policies

June 9, 2018

To continue, I don’t use the phone for anything other than calling, texting, checking emails, and taking pictures. I am dependent on my phone for business. The employees at the Mantua store in NJ have been very helpful but only so much they can do with the AT&T policies. I expect a NEW phone in an unopened box and not a Samsung. Also should not have to pay last month’s charges my time is too valuable!

Frustrated with AT&T

June 9, 2018

EXTREMELY frustrated!!!! I have had 4 phones since august 8/17 ,that phone would not swipe and the touch screen wouldn’t work, On 5/5/18 was sent out a REFURBISHED phone and that one stop working completely, black screen no charge, took 4 days to get another refurbished phone 5/21/18 which the screen turned neon green and couldn’t read. got sent another REFURBISHED phone and in less than 2 weeks this one also stoped working yesterday, another black screen. I have put about 20 hours into this project retrieving my contacts, since the phone would not take a charge or start up, going through all my texts to put phone number together with names, redownloading APS and passwords.. Spending hours in the AT&T store, spending hours on hold with you and the delivery services tracking my REFURBISHED phone. I expect some compensation for all of this time , I have paid good money, for mine and our 4 other phones and 3 tablets with At&T on time. now how to I get compensated for all my aggravation? I still don’t have a phone as of now. These have all been samsung androids. Your policies on sending back a phone to get another which is not new but REFURBISHED doesn’t help me, Why should I bother to pay the Bill???? on a phone I don’t have.

AT&T for 15 years

November 8, 2016

I have been with AT&T for 15 years, I might as well be a newbie cause being a veteran customer does not mean a thing. Today I called as I have 4 lines 2 iPhone 1 Samsung s5 and 1 iPad, I want to get rid of the Samsung as it was purchased 2 years ago for an exchange student that was living with us, he has since gone back to Germany, the phone sits in a desk drawer and is not used and has not been used for almost two years. AT&T does not want the phone back they want me to pay the remaining $151.58 and I can keep the phone but I don’t want the phone and neither does AT&T. We seem to be at a stalemate with a phone nobody wants all AT&T wants is their MONEY. They may consider going straight to Apple and taking advantage of their new plan. Pay a monthly amount for the iPhones for a year and do it again and again, much better deal than the AT&T give me your money plan. The Apple plan gives you an unlocked phone also.
