For an existing AT&T wireless account, call 800.331.0500, or dial 611 from an AT&T mobile phone. For an existing AT&T internet or home-phone account, call 800.288.2020. New-service sales use different numbers: 888.333.6651 for wireless and 866.861.6075 for internet.
The correct route depends on the service and whether you need support for an existing account or want to start new service. AT&T’s general support listing describes wireless and internet/home-phone support as available 24/7, while its detailed service pages show narrower hours for particular billing, account, technical, sales, accessibility and travel categories. Check the live AT&T support page just before calling because phone numbers and schedules can change.

Use the service-specific number rather than a number copied from an old forum post, search result or third-party directory. The service type and purpose—existing-account support versus new-service sales—determine which queue can handle your request.
Which AT&T line should you call?
For an existing wireless account
Call 800.331.0500 for mobile-service billing, account questions, calling problems, voicemail and other wireless support. If you are calling from an AT&T mobile device, 611 is the short code listed by AT&T for wireless support. The general support landing page presents wireless support as 24/7, but the detailed wireless page gives a narrower schedule for its bill-and-account category. Treat those as different levels of availability: 24/7 is the general listing, not a guarantee that every billing or account specialist is available at every hour.

For an existing internet or home-phone account
Call 800.288.2020 for an existing AT&T internet or home-phone account. This route is appropriate for internet connectivity, gateway or equipment questions, service status, billing and traditional home-phone support. AT&T’s general support page lists internet and home-phone support as 24/7. Its detailed internet page provides separate hours for billing/account assistance and technical support, so the task you select can affect the hours offered.
For new service or an order
Do not use an existing-customer number when you are trying to place a new order. New wireless service is listed at 888.333.6651. New internet service is listed at 866.861.6075. The new-service numbers have their own schedules and are intended for sales or starting service, not for resolving an existing account problem.
For specialized situations
Wireless customers outside the United States can use +1.314.925.6925, listed as 24/7. FirstNet subscribers should use 800.574.7000, also listed as 24/7, rather than the general consumer wireless line. TTY and voice accessibility contacts are 866.241.6567 and 866.241.6568; the wireless page lists Monday–Friday, 9 a.m.–9 p.m. Central Time for that section.

Why AT&T pages show different hours
AT&T’s general support landing page gives broad availability statements, while the wireless and internet pages break support into categories. A general “24/7” label can coexist with a bill-and-account schedule that covers only daytime and evening hours, because billing, technical support, sales and specialized accessibility queues are not necessarily staffed identically.
| Category | Detailed schedule reported on the service page | How to use it |
|---|---|---|
| Wireless bill and account | Monday–Friday, 8 a.m.–8 p.m. Central; Saturday–Sunday, 9 a.m.–7 p.m. Central | Use this as the detailed schedule for billing and account work, while recognizing that the general page separately lists wireless support as 24/7. |
| New wireless service | Monday–Friday, 8 a.m.–8 p.m. Central; Saturday–Sunday, 9 a.m.–7 p.m. Central | Call the new-wireless number during these listed sales hours. |
| Internet bill and account | Monday–Friday, 8 a.m.–8 p.m. Central; Saturday, 9 a.m.–7 p.m.; Sunday closed | Use for payment, billing and account questions on the detailed internet page. |
| Internet technical support | Saturday–Sunday, 5 a.m.–1 a.m. Central | This is the detailed technical-support schedule shown for the internet category; verify the live page for the complete current week and any exceptions. |
| New internet service | Monday–Friday, 8 a.m.–8 p.m. Central; Saturday, 9 a.m.–7 p.m.; Sunday closed | Use the new-internet number for orders rather than the existing-account line. |
| Wireless accessibility contacts | Monday–Friday, 9 a.m.–9 p.m. Central | Confirm that the listed TTY or voice route fits your needs before calling. |
Hours are stated in Central Time. If you live in another time zone, convert the schedule before calling. Because AT&T can revise both numbers and hours, open the current support page for your service immediately before dialing, especially on holidays or when a problem is urgent.
Official online alternatives to a phone call
A phone call is not the only official route. AT&T’s support pages provide several options that can be faster for a simple task or useful when the phone queue is busy.
Chat
Use the chat option on the AT&T support page for your service. Chat can be useful for straightforward account, billing and troubleshooting questions when you prefer written instructions or cannot make a voice call.
Free tools Windows power users keep installed
One-click scans. No signup required.
Sign-in-based help
Signing in can personalize troubleshooting and account tools. For internet customers, AT&T says sign-in can expose Wi-Fi details, service status and equipment speed tests. Those details can help distinguish a local Wi-Fi problem from a wider service issue before you contact support.
Billing and payment tools
The general support area links to bill viewing and payment without signing in. Use the signed-in route when you need account-specific information; use the no-sign-in payment option only when it is appropriate for the task and you have the required payment details ready.
Self-service troubleshooting
Official support links include wireless calling-issue help, voicemail guidance and internet gateway restart instructions. Follow the on-screen steps for your exact equipment and service rather than applying a reset procedure found on an unrelated website.

Good preparation reduces transfers and makes it easier for the representative to identify the affected service. You do not need to publish or send sensitive credentials to get ready.
- Identify the service. Decide whether the problem concerns wireless, internet, home phone, FirstNet or a new order.
- Classify the request. Say whether it is billing/account, technical support, an appointment, a payment, a new-service order or service while traveling.
- Use the matching number. Existing customers should use the support line; prospective customers should use the new-service line.
- Gather non-secret account details. Have your account number, service address or phone number available if you can access them, along with any order or appointment number. For internet appointment lookup, AT&T specifically identifies an order or account number and ZIP Code.
- Write down the symptoms. Note when the issue began, which device or service is affected, error messages, whether other devices work and any troubleshooting already completed.
- Protect authentication information. Never put a password, security answer or one-time verification code in an article, public post or message to an unsolicited caller. Enter sensitive information only through an official AT&T channel when you initiated the contact.
- Record the interaction. Note the date, time, representative’s name or identifier if provided, reference number and promised next step. This gives you a clear starting point if you need to follow up.
Choose the right path by problem
“My mobile phone cannot make or receive calls.”
Start with the existing wireless line, 800.331.0500, or dial 611 from an AT&T mobile. The official support area also provides a wireless calling-issues path. Before contacting support, note whether the problem affects one location, one phone or multiple lines, and whether text messaging or data still works.
“I need help with a wireless bill or account change.”
Use 800.331.0500 and select the billing or account route. The detailed wireless schedule is Monday–Friday, 8 a.m.–8 p.m. Central and weekends, 9 a.m.–7 p.m. Central. If your request is not urgent, signing in may let you view the bill or complete an account task without waiting on the phone.
“My home internet is down or slow.”
Call 800.288.2020 or use the internet troubleshooting tools. If you can sign in, check the service status, Wi-Fi details and equipment speed-test information that AT&T makes available. Have the gateway model or other equipment information, the affected devices and the time the problem began ready for the representative.
“I need to pay an internet bill or ask about an account.”
Use 800.288.2020, the bill/account option on the internet support page, or the official bill and payment tools. The detailed internet bill/account listing shows Monday–Friday, 8 a.m.–8 p.m. Central, Saturday 9 a.m.–7 p.m. and Sunday closed, even though the general support page describes internet/home-phone support as 24/7.
“I want to order service.”
Call 888.333.6651 for new wireless service or 866.861.6075 for new internet service. Keep the service address, preferred start date and any order information available, but do not assume a sales representative can resolve an existing billing or technical case.
“I am outside the United States.”
For wireless support while traveling abroad, use +1.314.925.6925. It is listed as available 24/7. Have the country you are visiting, the affected line and the symptoms ready so the representative can understand the travel context.
How to decide between calling, chat and self-service
Choose the channel according to the complexity and urgency of the task. A phone call is generally the clearest option when several services are affected, an account change requires verification, or you need to explain a complicated history. Chat can be more convenient for a short billing question or a written troubleshooting exchange. Signed-in tools are often the quickest way to view a bill, check a service status or run an equipment test without waiting for an agent.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsIf you are unsure which queue applies, start on AT&T’s service-specific support page rather than a broad web search. Select wireless, internet or home phone first, then choose billing, technical support, new service, appointment help or another category. The page may display a different phone number or schedule after you select the issue. This extra step helps prevent a transfer caused by calling a sales line for an existing-account problem.

What to expect during a support call
State the service, the affected number or location and the problem in one sentence when the call begins. For example: “My AT&T internet account at this address has been offline since 7 a.m.; the gateway is powered on, and I have already checked the service-status page.” A concise opening helps the representative place the call in the right category.
Keep your notes nearby while troubleshooting. Write down any reset, appointment, credit, replacement or follow-up instruction exactly as given, along with a case or confirmation number. If you are transferred, repeat only the key facts and mention the reference number so the next team can review the existing record. Do not guess at answers to security questions, and do not read a one-time code to a caller who contacted you unexpectedly.
What to do if the first route does not solve the problem
- Confirm the category. A sales queue, billing queue and technical queue may not have the same tools. If you reached the wrong category, ask to be transferred to the service-specific team rather than repeatedly explaining the issue to unrelated departments.
- Use the official online account tools. Check service status, appointment details, billing information or troubleshooting steps while you wait. The result may reveal whether the issue is account-specific, equipment-related or a scheduled visit.
- Ask for a reference number. Keep the case or interaction number, the date and the next promised action.
- Call back during the detailed category hours. If the issue is billing or account work, the narrower schedule may determine when the appropriate team is available, even when the general page displays 24/7 support.
- Recheck the live page. Numbers and hours are volatile. Do not rely on a number saved years ago or on a third-party directory when the official page provides the current route.
Safety and accuracy when looking for AT&T support
- Begin at AT&T’s official support site or use a number shown on your current bill, account portal or device documentation.
- Check that the page is actually for AT&T and that the number matches the service category before calling.
- Do not pay an unsolicited caller who claims to be support simply to “unlock” an account or fix a routine outage.
- Never disclose a one-time code to someone who contacted you unexpectedly. If a caller pressures you, end the call and start a new contact through an official channel.
- Do not confuse the FirstNet number with the consumer wireless number, or a new-service sales number with existing-account support.
