• Scam
• Suspicious

Community reports for 03 9003 1105 (0390031105) describe impersonation calls claiming Telstra internet issues, plus unsolicited service pitches from unidentified companies.

Telstra Impersonation and Unsolicited Calls from 03 9003 1105

Four contributors have reported incoming calls from 03 9003 1105 (also written as 0390031105) involving a mix of impersonation tactics and unsolicited service pitches. One report stands out: a caller falsely claimed the recipient had problematic internet access via Telstra, despite the recipient not being a Telstra customer at all. This impersonation approach, combined with pressure to act immediately, mirrors known telecom scam patterns where callers create false urgency around service issues that don't exist.

Beyond the Telstra impersonation, callers from 0390031105 have pitched sustainability services from unnamed companies and electricity comparison offers. The lack of transparency about the company behind these calls, combined with their unsolicited nature, has raised red flags for contributors.

Caller Tactics Reported with 03 9003 1105

The Telstra impersonator from 03 9003 1105 employed two key tactics: false impersonation of a major telecommunications provider and artificial urgency. By claiming an existing service problem required immediate attention, the caller attempted to bypass rational decision-making. This approach is consistent with tech support and telecom scams designed to either extract payment, gain remote access to devices, or collect personal information.

The sustainability service caller from 0390031105 took a different angle, pitching an unidentified company without clear credentials. Contributors noted the pitch felt suspicious, suggesting the vague or evasive description of the service itself raised concerns. These varied tactics indicate the number may be used by multiple outbound calling operations or a call centre handling diverse campaigns.

Report Patterns and Timing

Calls from 03 9003 1105 have arrived across different times: one after-hours call targeting a private, unregistered number, a mid-morning sustainability pitch, and daytime spam calls about electricity comparison. The after-hours call to an unregistered number is particularly concerning, as it suggests either data harvesting from a breach or illegally sourced contact lists. All four reports came via answered calls, meaning contributors engaged with the callers before recognising the issue.
