AT&T Wireless Customer Service Phone Number and Contact Options

Choose the Correct AT&T Wireless Support Route

AT&T Wireless support depends on whether your issue involves billing, account access, technical support, activation, device unlock, eSIM, international roaming, prepaid service, FirstNet, business wireless, trade-ins, device protection, returns, fraud, a store visit, or a formal unresolved dispute.

  • Postpaid wireless billing, account, plan, or technical support: Call 1-800-331-0500, dial 611 from an AT&T wireless phone, sign in to myAT&T, or use chat.
  • AT&T Prepaid: Use 1-800-901-9878, dial 611 from an AT&T Prepaid phone, or use the prepaid account tools.
  • New wireless service: Call 1-888-333-6651 or use AT&T’s online ordering tools.
  • International travel or roaming: Use AT&T travel support, international plan resources, or call +1-314-925-6925.
  • Device unlock: Use AT&T’s device unlock page and check eligibility before contacting support.
  • Returns or exchanges: Use AT&T’s wireless return policy or call 1-800-331-0500.
  • Trade-in issue: Use the AT&T Trade-in site, trade-in status page, and support route tied to your confirmation number.
  • Device protection or insurance claim: Use the device protection or insurance claim route shown in your plan documents.
  • Wireless fraud or unauthorized account: Use AT&T’s wireless fraud page or call 1-877-844-5584.
  • Business wireless: Use AT&T Business support or the number shown on the business account.
  • Corporate or investor question: Use AT&T corporate or investor resources, not the wireless customer-service line.

Information To Have Ready Before Contacting AT&T Wireless

Before calling, chatting, visiting a store, reporting fraud, starting a return, or escalating a complaint, gather the details that apply to your issue:

  • AT&T account number or wireless phone number
  • Account owner name, billing ZIP code, and account passcode or approved verification method
  • Device make, model, IMEI, serial number, SIM, or eSIM details if relevant
  • Current bill, previous bill, disputed line item, payment date, and payment confirmation
  • Plan name, promotion, trade-in offer, upgrade details, or installment plan information
  • Order number, tracking number, return label, trade-in confirmation, or case number
  • Store location, date, receipt, associate name only when appropriate, and written store notes
  • Fraud claim details, unauthorized account notices, collection letters, or identity-theft documents only through official secure channels
  • Device protection claim number or replacement-device details if applicable
  • A short timeline of what happened and the resolution you are requesting

For public reviews, do not post wireless numbers, account numbers, passcodes, IMEIs, SIM/eSIM information, Social Security numbers, payment details, home addresses, order numbers, trade-in confirmation numbers, fraud claim numbers, tracking numbers, store receipts, or screenshots of your bill or account.

  • Returns, exchanges, defective devices, replacement devices, device protection, and warranty routing
  • Trade-in credits, promotional offers, upgrade credits, rebate status, and installment billing
  • Prepaid account balance, prepaid refill, prepaid activation, prepaid account number, and prepaid service questions

  • Store complaints, account access problems, cancellation, transfer of billing responsibility, and unresolved disputes

Billing, Account Support, and Unexpected AT&T Wireless Charges

Wireless bills may change because of plan changes, partial-month charges, device installments, upgrade charges, taxes and surcharges, international roaming, overage or usage charges, device protection, add-ons, promotional credits, AutoPay or paperless-billing changes, or a discount ending.

Before disputing a bill, download the current bill and the prior bill, compare each line, identify the exact charge, and ask AT&T for the expected correction date. Promised credits may not appear until a later billing cycle.

Wireless Technical Support, Outages, and Device Help

AT&T Wireless support can help with dropped calls, slow data, no service, voicemail, texting, hotspot use, eSIM, device setup, device transfer, network settings, and outage checks. Use AT&T’s device support and wireless help pages before assuming the issue is only your phone or only the network.

For urgent safety, medical, emergency, 911, or location-service issues, contact emergency services or the appropriate official provider. CustomerServiceNumbers.com does not provide emergency, technical engineering, device repair, legal, or network-safety advice.

Activation, SIM, eSIM, Number Transfer, and New Devices

If your issue involves activating a new phone, downloading an eSIM, switching from a physical SIM, transferring a number, changing devices, upgrading, or bringing your own device, use AT&T’s activation and wireless device tools. Keep your IMEI, SIM or eSIM details, order number, account PIN, transfer PIN, and prior carrier information private.

AT&T Prepaid Support

AT&T Prepaid has separate account tools and support routing from regular AT&T Wireless postpaid service. Prepaid customers can dial 611 from an AT&T Prepaid phone or call 1-800-901-9878.

Prepaid customers should use prepaid support for prepaid balance, refill, activation, account number, prepaid SIM, prepaid device unlock, and prepaid payment issues.

International Travel, Roaming, and Calling From Abroad

If your issue involves international roaming, International Day Pass, cruise use, roaming charges, text or data abroad, calling from another country, or a phone that will not connect while traveling, use AT&T’s travel support route. AT&T lists travel-abroad support at +1-314-925-6925.

Roaming, international calling, cruise packages, satellite, and international data can be expensive and plan-specific. Review your plan terms and AT&T’s current international support materials before traveling.

Device Unlock Requests

AT&T provides a device unlock page where customers can submit an unlock request and check unlock eligibility. Unlock rules may differ for postpaid and prepaid devices. Common requirements can include purchase date, paid-off installment balance, account status, fraud status, and whether the device has been reported lost or stolen.

Do not post your IMEI, unlock request number, wireless number, account details, or email screenshots in a public review.

Returns, Exchanges, Defective Devices, and Device Protection

AT&T’s wireless return policy can depend on where the device was purchased, how long it has been since purchase, whether the device is new or defective, whether a replacement was shipped, and whether a device protection or insurance claim applies. AT&T’s wireless return policy says customers who bought a wireless device through AT&T channels generally have 14 days to start a return or exchange.

Before returning a device, back up your data, remove locks and accounts, factory reset the device, photograph the condition, keep the tracking number, and confirm exactly which device or accessory must be returned. Do not post device serial numbers, IMEIs, return labels, or tracking numbers publicly.

Trade-Ins, Promotions, Upgrade Credits, and Rebates

AT&T trade-in and promotional credits can involve eligibility rules, device condition, IMEI, purchase channel, plan requirements, trade-in timing, mailing kit, in-store return, receipt, and billing-cycle timing. AT&T says trade-in bill credits may take multiple billing cycles to appear.

Save the offer terms, device condition photos, trade-in confirmation, mailing receipt, tracking number, and AT&T bill showing credits. Do not post trade-in confirmation numbers, IMEIs, shipping labels, or account screenshots in public comments.

Fraud, Unauthorized Accounts, SIM Swap Concerns, and Suspicious Messages

If you believe someone opened an unauthorized AT&T Wireless account, changed your account without permission, used your identity, performed a SIM swap, or accessed your account, use AT&T’s wireless fraud route. For suspicious emails, AT&T directs customers to forward suspicious messages to abuse@att.net.

Do not post Social Security numbers, driver’s license images, fraud forms, police reports, account numbers, phone numbers, SIM/eSIM details, IMEIs, collection letters, or credit-report screenshots in a public review.

Business Wireless and FirstNet Support

Business wireless accounts, enterprise accounts, port activations, device insurance, and FirstNet support may use different support routes from regular consumer wireless accounts. Use AT&T Business support or the phone number shown on the business bill when available.

Do not post business account numbers, employee phone numbers, device lists, company emails, FirstNet account details, invoices, or porting documents in public comments.

Store Issues, Authorized Retailers, and In-Person Help

AT&T store issues may involve corporate stores, authorized retailers, device sales, trade-ins, accessory purchases, SIM changes, returns, upgrades, plan changes, or promised promotions. Store policies and support routes may differ depending on whether the location is AT&T-owned or independently operated.

For store complaints, keep the receipt, store address, date, time, device details, offer details, and written notes. Do not post employee full names, receipt numbers, wireless numbers, account screenshots, or payment details in a public review.

Accessibility, Disability Resources, Privacy, and Account Security

AT&T provides accessibility and disability-support resources for customers who need help using AT&T services, devices, websites, or account tools. AT&T also provides privacy and security resources for account data, advertising choices, and privacy requests.

If you receive a suspicious call, text, SIM swap message, device order, trade-in message, refund offer, or login code request claiming to be from AT&T, verify it through AT&T.com, the myAT&T app, or the official phone number before sharing information.

Formal Disputes, FCC Complaints, and Escalation

If ordinary AT&T Wireless support does not resolve your issue, keep your complaint organized. AT&T provides a Notice of Dispute process for unresolved disputes after customer service has not resolved the issue. The FCC also accepts informal consumer complaints about telecommunications billing, service, privacy, accessibility, unwanted calls, and related issues.

CustomerServiceNumbers.com does not provide legal, arbitration, regulatory, credit, identity-theft, contract, or FCC complaint advice. Review AT&T’s current agreement, dispute process, and official communications before taking action.

How to Escalate an AT&T Wireless Complaint

If your AT&T Wireless issue is not resolved after the first contact, keep your complaint organized and use the correct route.

  1. Identify whether the issue involves billing, technical support, prepaid, activation, unlock, international roaming, trade-in, return, fraud, device protection, store issue, business account, or FirstNet.
  2. Call 1-800-331-0500, dial 611 from your AT&T Wireless phone, sign in to myAT&T, or use chat.
  3. For prepaid issues, use 1-800-901-9878 or the AT&T Prepaid account portal.
  4. For fraud or unauthorized wireless accounts, use AT&T’s wireless fraud route and keep all identity-theft documentation private.
  5. For trade-ins, save the offer terms, mailing receipt, tracking number, confirmation number, and bill statements showing credits.
  6. For returns or exchanges, follow AT&T’s return policy, keep the label and tracking number, and confirm the device was received.
  7. For store complaints, keep the store location, receipt, date, time, promotion details, and written notes.
  8. Ask for a case number, supervisor review, written explanation, credit timeline, return confirmation, fraud case number, or next step.
  9. If ordinary support does not resolve the matter, review AT&T’s Notice of Dispute process or the FCC Consumer Complaint Center.
