AT&T Impersonation Scams
Scammers impersonate AT&T with fake billing alerts and SIM swap attempts. AT&T will never ask you to confirm a SIM change or bill payment via a link in an unsolicited text.
Last reviewed: 1 June 2026
AT&T is one of the largest US mobile carriers, and its scale makes it a prime impersonation target. Phishing texts and emails mimicking AT&T billing notifications direct customers to fake login pages, while SIM swap fraud exploits AT&T's brand to convince targets to 'confirm' a porting request that hands control of their number to an attacker.
AT&T's name is also used in tech-support scams, where callers claim a compromised device requires remote access software to diagnose.
How scammers impersonate it
- Sending texts claiming an AT&T bill is overdue with a link to a phishing payment page
- Creating fake AT&T login pages to harvest myAT&T account credentials
- Calling customers claiming to be AT&T security and asking them to confirm a SIM transfer
- Sending fake account suspension notices requiring immediate re-verification
- Advertising fake AT&T customer service numbers via search engine ads
What the real organisation never does
- Ask you to confirm a SIM transfer or port your number via an unsolicited call or text
- Request your myAT&T password or full payment card details via text or email link
- Contact you via a phone number not listed at att.com
- Ask you to install remote-access software to resolve a billing or device issue
Common red flags
- Text about an overdue bill with a link to a non-att.com domain
- Call from someone claiming to be AT&T asking you to confirm a SIM transfer you did not request
- AT&T customer service number found via a search ad rather than att.com
- Account suspension notice with an urgency deadline requiring action via an external link
- Email from a sender domain other than @att.com or @email.att.com

- Set a wireless passcode on your AT&T account to make SIM swaps harder to perform fraudulently
What to do if you're targeted

Frequently asked questions
I received a text saying my AT&T payment is overdue — is it real?
Check your bill inside the myAT&T app before paying anything. Do not click payment links in texts. If your account is genuinely overdue, the balance will be visible in the app.
