Impersonation and Nuisance Reports for 03 9003 1103

Six contributors have reported calls from 03 9003 1103 (also written as 0390031103), with a pattern of unclear caller identity, suspicious impersonation attempts, and nuisance behaviour. The reports span February to April 2026 and describe several distinct call types: false Telstra claims, silent calls with no purpose, electricity comparison sales calls, and vague callback requests.

The most concerning report about 0390031103 involves a caller claiming affiliation with Telstra, specifically referencing an IP address issue. The contributor who received this call from 03 9003 1103 noted they are not a Telstra customer, suggesting either data harvesting or random targeting. Another report describes silent calls with heavy breathing and laughter, a harassment pattern distinct from typical telemarketing.

What Callers from 03 9003 1103 Say

Reports about 03 9003 1103 reveal several distinct caller approaches. One contributor reported a Telstra impersonation attempt focused on IP address concerns, a common tech support scam tactic. Another call involved a generic callback request where the caller asked the contributor to leave a message for customer service to return the call; this caller had an American male accent and the contributor chose not to engage.

A third approach documented in reports of 0390031103 involved questioning whether the recipient is the main internet user, followed by an abrupt hang-up when the answer was no. That caller had an Indian accent and was described as sounding rude. A fourth call from 03 9003 1103 was identified as an electricity comparison offer, typical telemarketing behaviour. The silent call incident, where the contributor heard only heavy breathing and laughter, stands apart as pure nuisance activity with no sales or impersonation intent.

Call Patterns and Timing

The six reports for 0390031103 are spread across three months, with multiple calls in late March 2026. Two calls arrived early morning (around 4-5 AM Australian time), which is atypical for legitimate business outreach and suggests either automated systems or overseas call centres. One call came mid-morning (10:22 AM) during standard business hours.

Contributors reported varied caller accents and languages, including American English and Indian English, indicating possible offshore or multi-location call operations. The mix of call purposes-impersonation, sales, callback requests, and silent calls-suggests either different campaigns using the same number or a spoofed number being exploited by multiple bad actors.
