WRITE A REVIEWFrequently Asked Questions
Should I call back 03 9003 3399 if they hang up?
No. Do not return calls to 0390033399. If the call was legitimate, Telstra will contact you again through official channels. Returning the call to 03 9003 3399 may connect you directly to the scammer's line, which is often the goal of such calls.
How can I verify if a call about my internet is really from Telstra?
Telstra will never initiate unexpected calls claiming your internet is on a public network without prior context. If you suspect a call is from Telstra, end the call and ring Telstra directly on 13 2200. Do not use any number the caller provides. Always verify by calling the official number on your Telstra bill or the Telstra website, never from a number mentioned during an unsolicited call to 03 9003 3399.
What is a public network scam?
Scammers falsely claim your device or internet connection is exposed on a public network to create alarm. The tactic aims to convince you that urgent technical action is needed, making you more likely to grant remote access or provide payment details. The claim made during the call from 0390033399 follows this pattern exactly.
Can I report this number to Telstra directly?
Yes. Contact Telstra on 13 2200 and inform them of the impersonation attempt from 03 9003 3399 (0390033399). Telstra maintains records of impersonation reports and may take action against the fraudulent caller. Also report to Scamwatch at scamwatch.gov.au for official documentation.
Is it safe to answer calls from unknown numbers like 03 9003 3399?
You can answer to identify the caller, but do not disclose personal information. Once 0390033399 identifies itself as Telstra and makes claims about your internet, it is safe to hang up and verify independently by calling Telstra on 13 2200. This approach lets you stay aware of attempts without engaging with the scammer.
What should I do if I already gave information to the caller from 03 9003 3399?
If you provided personal details or financial information to this number, contact your bank and Telstra immediately on 13 2200. Monitor your accounts for unauthorised activity. File a report with Scamwatch (scamwatch.gov.au) and ReportCyber (cyber.gov.au) if financial loss occurred. Document the call details including time and what information was shared with 0390033399.
