Mixed Suspicious Activity Reported for 03 9002 4219

Eight contributors have flagged calls from 03 9002 4219 (also written as 0390024219) for a range of concerning behaviours. Unlike numbers with a single consistent pattern, this Melbourne-based Primus Telecommunications local service shows multiple distinct tactics across reports. Contributors describe silent calls, robocalls, personal information requests phrased as detective-like questioning, survey callbacks, and one notable Telstra impersonation claiming home IP vulnerability.

The variety of tactics suggests this number may be cycling through different approaches or being used by multiple parties. Three contributors reported the number to be malicious enough to block.

Specific Calls and Claims from 03 9002 4219

The most serious report about 0390024219 involved a caller claiming affiliation with Telstra, stating the recipient's home IP was exposed and vulnerable. The caller created urgency around the claimed security issue, then ended the call abruptly when questioned.

Other reports from 03 9002 4219 show deliberate information-gathering. One contributor described the caller asking numerous questions "like a detective" with a "dodgy feeling." Another report noted the number asked specifically about mortgage details, then indicated someone would call back with an unsolicited sales offer.

Silent calls account for two separate reports. One lasted approximately 30 seconds with no words spoken; another resulted in complete silence. A fourth contributor who called back 03 9002 4219 reached an automated message stating the number was incorrect or doesn't exist, consistent with robocall behaviour.

Two voicemail messages from 0390024219 referenced an "Australian Research Centre" conducting cost-of-living surveys, though contributors reported the voicemail quality was poor and the legitimacy questionable.

Report Patterns and Call Activity

Reports for 03 9002 4219 span from July 2024 to February 2026, indicating sustained activity over an 18-month period. The most recent Telstra impersonation report arrived in December 2025. Most reports were from answered calls; two arrived as voicemail messages.

The mixed tactics across reports suggest either inconsistent operation or multiple parties using the same line. The silent calls in January and August indicate automated probe activity checking whether numbers are active. The callback request and survey voicemails suggest concurrent use for telemarketing. The Telstra impersonation and personal information request stand out as deliberate scam attempts.

What to Do If You Receive a Call from 03 9002 4219

If 03 9002 4219 calls you:

• Do not: Answer if you don't recognise the number; share personal information, mortgage details, or IP/network information; return a call if it goes to voicemail without identifying the caller
• Do: Let unknown calls go to voicemail; block 0390024219 immediately if the caller is silent or abusive; hang up if any caller claims to be from Telstra but you didn't initiate contact
• Verify independently: If a caller claims to be from Telstra, hang up and call Telstra directly using the number on your bill or their official website to check whether they initiated contact
• For silent calls: A single silent call may be accidental, but repeated calls from 03 9002 4219 with no speech are a sign of robocall activity and should be blocked

What to Do If You Receive a Voicemail from 03 9002 4219

If a voicemail arrives from 0390024219:

• Do not: Return the call; provide personal information in response to survey requests; assume the caller is legitimate based on the message alone
• Do: Delete the message; block the number; mark it as spam on your phone
• For survey claims: Legitimate research organisations will provide verifiable contact details and allow you to opt out. A voicemail with poor audio quality requesting callback is not typical of established research bodies
