Telstra Impersonation Report for 04 7874 5479
One contributor has reported receiving a suspicious call from 04 7874 5479 (also written as 0478745479) claiming to be from Telstra. The caller demonstrated knowledge of the recipient's name and specifically mentioned their Optus mobile device, discussing supposed security concerns. The call ended abruptly, which is typical of scammers testing whether they've reached an engaged target before escalating their pitch.
The number is registered as an Optus mobile, which scammers frequently exploit to add false credibility. Callers impersonating major telecommunications providers like Telstra often use this tactic to bypass initial scepticism, especially when they reference competing networks like Optus.
What the Caller from 04 7874 5479 Claimed
The contributor reported that the caller confirmed their name before pivoting to device security concerns. This two-step approach is deliberate: confirming personal details first builds false trust, making recipients more likely to engage with subsequent claims about device vulnerabilities or account issues.
The mention of the recipient's Optus mobile suggests the caller had prior information, whether from data harvesting, social engineering, or simply cold-calling multiple people with common Optus accounts. The abrupt call termination from 0478745479 may indicate the caller was screening for responsiveness before a follow-up attempt with a fuller scam script.
What to Do If You Receive a Call from 04 7874 5479

WRITE A REVIEWFrequently Asked Questions
Why did the caller from 04 7874 5479 confirm my name before mentioning device security?
Confirming your name first is a trust-building tactic. By demonstrating they know who you are, scammers make their subsequent false claims about security issues seem more credible. The contributor's experience with 0478745479 shows this exact pattern: name confirmation followed by a device security pitch.
Should I call back 04 7874 5479 if they say there's a security problem with my phone?
No. Do not return calls to 0478745479 or any unknown caller claiming to be from Telstra or Optus. Legitimate providers never cold-call about device security issues. If you're concerned, hang up and call your provider directly using the number on your bill or their official website.
Why is 04 7874 5479 registered as an Optus mobile if it's a Telstra impersonation?
Scammers often use legitimate phone numbers stolen from or leased through mobile providers to appear genuine. The number 0478745479 being an Optus mobile doesn't mean Optus is behind the scam-it means a scammer is using an Optus service to impersonate Telstra and target Optus customers specifically.
What does it mean that the call from 04 7874 5479 dropped suddenly?
Abrupt call termination is common in scam testing. The caller from 0478745479 may have been screening for engagement before escalating to financial or credential requests. If you'd engaged further, the scammer likely would have invented an urgent security issue requiring you to provide passwords, banking details, or remote device access.
How can I prevent calls from 04 7874 5479 in future?
Block 0478745479 in your phone settings. Register your number on the Do Not Call Register at donotcall.gov.au, though this won't stop dedicated scammers. For additional protection, consider enabling call filtering through your Optus account settings or using third-party call-blocking apps.
Should I report this to Optus since 04 7874 5479 uses their network?
Yes. Contact Optus and report that the number 0478745479 is being used for impersonation scams. Optus can flag the account and may suspend or investigate it. You should also report to ACMA via acma.gov.au so the regulator can take enforcement action against repeat offenders.
