Telstra Impersonation Reports for 03 9003 1108
Three contributors have reported calls from 03 9003 1108 (also written as 0390031108) impersonating Telstra staff. The scam pattern involves callers falsely claiming to represent Telstra's internet or security departments, with specific attempts to install remote access software on victims' devices.
The most detailed report about 0390031108 describes a caller claiming to be from Telstra Internet who explicitly requested the installation of RealVNC Server - a legitimate remote access tool commonly exploited in tech support scams. Once installed, such software allows scammers to access banking details, passwords, and personal files without the victim's knowledge.
What Callers from 03 9003 1108 Say
One contributor reported that a caller from 03 9003 1108 claimed to represent a 'Technical Department' but could not identify which business they were calling from - a red flag suggesting either poor scam preparation or intentional vagueness. This same caller employed a common social engineering tactic by immediately asking 'how are you' to establish false rapport, then hung up when the recipient became suspicious.
Another report indicates the caller specifically identified themselves as 'Telstra security', lending false legitimacy to the request. The consistency of Telstra impersonation across multiple reports from 0390031108 suggests this number is actively used as part of a coordinated scam operation targeting Australian internet customers.
Call Patterns and Timing
Community reports for 03 9003 1108 show calls arriving across different times, with reports logged in late evening (01:09 UTC) and early morning hours (07:45 UTC), suggesting either international calling or deliberate timing to catch people off-guard. All four reports came within a 12-day period in February 2026, indicating concentrated scam activity from this number.
Three of the four calls were answered by contributors, meaning 0390031108 successfully connected with real people - a typical success rate for scammers who use multiple numbers and persistent dialling. One report also noted a telemarketing call about electricity comparison on the same number, which may indicate the number was either repurposed, spoofed, or listed in compromised contact databases.

WRITE A REVIEWFrequently Asked Questions
What is RealVNC Server and why would a scammer want me to install it?
RealVNC Server is legitimate remote access software, but when requested by unsolicited callers claiming to be from 03 9003 1108 or Telstra, it's a major scam warning sign. Once installed, it gives the scammer complete control of your device - they can access banking apps, steal passwords, view files, and impersonate you online. Real Telstra technicians do not cold-call asking you to install software. If Telstra genuinely needs remote access, you initiate contact with them directly on 131 133 first.
How can I verify if a call claiming to be from Telstra is genuine?
Never trust caller ID or claims. If 03 9003 1108 or any number claims to be Telstra, hang up immediately and call Telstra directly on 131 133 (from your phone bill or official Telstra website). Legitimate Telstra staff will never ask you to install software during an unsolicited call, request remote access, or demand payment over the phone without a prior account issue you reported to them first. Real service providers always support you hanging up and calling back on verified numbers.
What should I do if I already gave the caller from 0390031108 remote access to my computer?
Act immediately: (1) Disconnect the computer from the internet, (2) Change all passwords (banking, email, social media) from a different device, (3) Contact your bank and notify them of potential fraud, (4) Contact Telstra on 131 133 to report the scam, (5) Run a malware scan using Windows Defender or reputable antivirus software, (6) Consider having a technician check for backdoors. If you provided banking details or downloaded any files suggested by the caller, monitor your accounts closely for unauthorised transactions.
Why does the same number 03 9003 1108 sometimes claim to be different departments?
Scammers often cycle through different pretexts from the same phone number to maximise attempts. Reports from 0390031108 show claims of 'Telstra Internet', 'Telstra security', and a generic 'Technical Department' - all variations designed to confuse victims and increase the chance that at least one story lands with someone who feels vulnerable or unsure. This variation tactic is common in impersonation scams because the actual goal is always the same: gaining device access to steal money or data.
Is 03 9003 1108 definitely a scam or could it be legitimate Telstra?
All four reports about 03 9003 1108 (0390031108) describe scam tactics: impersonation without clear business identification, unsolicited installation requests, and evasive behaviour when questioned. No legitimate Telstra contact would ask you to install remote access software during a cold call. Telstra's actual support number is 131 133 and they initiate contact only for issues you've reported to them. If any number claims to be Telstra and requests access to your device, it is a scam.
Should I answer calls from 03 9003 1108 to report them or just block the number?
Block and do not answer. There is no benefit to engaging with 0390031108 - scammers do not use verified numbers that can be traced, and answering signals to them that your number is active, potentially leading to more calls. Simply block the number in your phone settings (most devices have a block option), then report it to Scamwatch at scamwatch.gov.au and ACMA at acma.gov.au. Your report to authorities is far more valuable than any conversation with the scammer would be.
