For a bill or account question, or for tech help with AT&T Fiber or Internet Air, call AT&T at 800.288.2020. New service has its own line, 866.861.6075. Everything on this page comes from att.com (checked Oct 17, 2026). Our number, (888) 428-0573, is a sales line for new orders. Reliable Internet Inc is an authorized sales agent and can't reach your AT&T account, so for account help use the AT&T options below.
Ways to Contact AT&T Support
Chat starts from AT&T's internet support page, where AT&T asks a few questions before connecting you to a rep. If you sign in, you can see your Wi-Fi details, check service status and test your equipment's speed. Appointments can be looked up with an order number, or with your account number and ZIP code. AT&T keeps separate support sections for Internet, Internet Air and legacy DSL customers.
The AT&T Guarantee promises a tech expert within 5 minutes or a callback at a time you choose. That applies to AT&T Fiber, Internet Air and postpaid wireless customers, and the 5 minutes start once you're routed to help. Fiber customers can also get same-day or next-day technician appointments. With both Fiber and AT&T wireless, a tech support call stays with one agent from start to finish (att.com/why-att/guarantee).

Outage Credits
AT&T credits a full day of service when an AT&T Fiber or Internet Air network interruption lasts 20 minutes or more. Restrictions and exclusions apply. With Fiber and an eligible AT&T unlimited wireless plan, Internet Backup moves your home connection to cellular data during a fiber outage, at no extra cost.
Moving Your AT&T Service
Existing customers can transfer service through AT&T's online move portal, or call 800.288.2020, the number AT&T's city pages give for moving. Which service you keep depends on what's built at the new address: Fiber, Internet Air or both. To shop for service at a new address, att.com/moving lists 844.261.6737.
Cancelling AT&T Internet
Current AT&T internet plans have no term commitment, so there's no early termination fee. Return your equipment after you cancel. AT&T's fee schedule charges $150 for an unreturned Wi-Fi gateway, $200 for an unreturned All-Fi Hub and $65 for each Wi-Fi extender. Older plans with a term commitment could carry a prorated fee of up to $180.
Paying Your Bill
You can view your bill, make a payment or set up AutoPay online, and AT&T also lets you pay without signing in. AutoPay with paperless billing from a bank account takes $10 a month off your internet price. With a debit card it's $5, and other credit cards don't qualify. Paying with help from a rep or retail agent can cost up to $5.
Before You Call AT&T
Use 800.288.2020 for billing, account and tech help, and 866.861.6075 to start new service. Have your account number, service address and ZIP code ready, plus your order number if you're asking about an install.
Plenty can be done without a call. Signing in shows service status and runs an equipment speed test, and chat can take billing questions.
