AT&T Customer Service Phone Number & Live Chat — Fastest Ways to Skip the Queue
Don’t feel like navigating endless phone menus? These are the three fastest ways to reach a real person.
| Method | How | Wait time |
|---|---|---|
| Method Dial 611 (wireless customers) | How Call from your AT&T mobile phone — it skips the main automated system | Wait time Fastest |
| Method Live Chat | How Go to https://www.att.com/support/contact-us → click “Chat with a rep” | Wait time Usually under 5 min |
| Method Main wireless support number | How +1-800-331-0500 — open 24/7 | Wait time Varies |
If you’re calling about internet or home phone service, use +1-800-288-2020 instead. For most other issues, dialing 611 from your AT&T mobile is usually the quickest option.

AT&T Billing Phone Number — Dispute a Charge, Overcharge, or Bill Error
If you were overcharged, don’t understand something on your bill, or want to dispute a charge, these are the right contacts. For billing issues, chat is often better because you get a written record of the conversation.
| Service | Phone / contact | Hours |
|---|---|---|
| Service Wireless billing | Phone / contact +1-800-331-0500 or dial 611 | Hours 24/7 |
| Service Internet / Home Phone billing | Phone / contact +1-800-288-2020 | Hours Mon–Fri: 8am–8pm CT / Sat: 9am–7pm CT / Sun: CLOSED |
| Service Live Chat (all services) | Phone / contact https://www.att.com/support/contact-us | Hours Same hours as above |
If you’re disputing a charge, use Live Chat instead of calling. The transcript is saved, which can help if the issue isn’t fixed the first time.
AT&T Tech Support Phone Number — Internet Down, Phone Not Connecting, or Outage
Phone not connecting? Internet down? Here’s who to call based on your service.
| Service type | Phone number | Hours |
|---|---|---|
| Service type Wireless tech support | Phone number +1-800-331-0500 or dial 611 | Hours 24/7 |
| Service type Internet tech support | Phone number +1-800-288-2020 | Hours Mon–Fri: 8am–8pm CT / Sat–Sun: 5am–1am CT |
| Service type Home phone tech support | Phone number +1-800-288-2020 | Hours Mon–Sat: 8am–8pm local time |
Internet tech support has longer weekend hours (5am–1am CT on Saturday and Sunday), which actually makes weekends one of the easier times to reach them. Billing calls on Sundays, however, are not available.
