Why did a scam text appear in my real Telstra SMS thread?

Scammers use a technique called 'Sender ID Spoofing' to make their messages appear under the name 'Telstra', grouping them with your genuine network texts.

How do I check my real Telstra bill?

Open the official My Telstra app on your smartphone, or go directly to telstra.com.au on your computer to view and pay your bills securely.

Are those calls from 'Telstra NBN Support' real?

Almost never. Telstra will not call you unsolicited to warn you that your computer is sending error messages or that your NBN is about to be disconnected due to hacking.

Detecting fake Telstra alerts

Telstra communicates differently from scammers. Watch out for these aggressive tactics designed to steal your financial details.

The 'Service Disconnection' threat

A text message claiming a recent payment failed and your mobile or NBN service will be disconnected today unless you click a link.

Fake 'Telstra Plus' points expiring

An email or SMS stating you have thousands of Telstra Plus points expiring tonight, urging you to log in via a link to claim a reward.

Overpayment refund scams

A message claiming Telstra overcharged your account and needs your bank details or credit card to process a refund.

Tech support cold calls

Scammers calling claiming to be 'Telstra Tech Support' saying your internet is slow or infected, asking to remotely access your computer.

What IsThisSpam checks before you trust a sender

Quick verdicts are useful, but the real value is understanding why something looks safe, uncertain, or risky.

Links leading to login screens

Never click a link in an SMS to securely log in to your account or pay a bill. Always use the My Telstra app.

Spoofed Sender IDs

Scammers can manipulate text messages to appear in the same thread as your real Telstra messages.

Pressure-driven decision framing

Scams force immediate action—'Your internet will be cut off in 24 hours'—to prevent you from verifying the claim.

Remote access requests

Legitimate Telstra support will never call you out of the blue and ask you to install TeamViewer or AnyDesk on your computer.
