One contributor has reported receiving a silent call from 03 9113 2433 (also written as 0391132433). When the contributor picked up, the caller immediately hung up without saying anything.

What to Do If You Receive a Call from 03 9113 2433

Why Callers Hang Up Immediately
Silent calls followed by immediate hang-ups typically serve one of two purposes: automated dialling systems testing whether a number is active and monitored by a person, or callback scams designed to prompt you to return the call. In both cases, the intent is harmful. Never return a call to a number that has hung up on you, as this confirms your line is active and monitored.

WRITE A REVIEWFrequently Asked Questions
Why would someone call and hang up immediately from 03 9113 2433?
Silent calls that disconnect immediately are typically automated verification systems or callback scams. The caller either confirms your number is active for later targeting, or hopes you'll call back to an expensive number. Never return a call from 0391132433 if they hang up on you.
Is 03 9113 2433 a legitimate business number?
The number is allocated to Primus Telecommunications Pty Limited as a local service in Victoria, so it has a legitimate allocation. However, legitimate businesses do not make silent calls that hang up immediately. The behaviour reported for 0391132433 suggests unauthorised use or a scam operation.
What should I do if 03 9113 2433 calls me repeatedly?
Block the number immediately in your phone settings. Do not answer or return calls. Report repeated calls from 0391132433 to ACMA (acma.gov.au) and your phone provider. If the calls continue after blocking, contact your provider's fraud team.
Could 03 9113 2433 be spoofed from a legitimate provider?
Yes. Scammers can spoof legitimate-looking numbers including those allocated to real providers like Primus. Just because 0391132433 appears to be from a Victorian local service doesn't mean the actual caller is from Primus or that organisation. Never trust caller ID alone.
Why is a silent call considered nuisance or scam?
Silent calls serve no legitimate purpose. Legitimate businesses identify themselves when you answer. A silent call from 03 9113 2433 that hangs up is either testing whether your number is active for callback scams, or automated dialling by scammers. Treat it as a scam indicator.
Should I call back 0391132433 to find out who it is?
No. Do not call back 03 9113 2433 under any circumstances. Returning the call confirms to scammers that your number is monitored, and may connect you to a premium-rate service or further scam operation. If you need to verify a legitimate business, look up their official number independently.
