WRITE A REVIEWFrequently Asked Questions
What does a silent call from 07 3815 5729 typically mean?
Silent calls where the line rings but no one speaks are often automated callback scams or robocall testing. The contributor's report of 0738155729 keeping ringing with nothing on the line suggests an automated system cycling through numbers. Do not return the call, as this is the scammer's goal.
Should I return a call to 07 3815 5729 if it rings but disconnects?
No. Never return a call to 0738155729 or any silent number, especially if it disconnected when you answered. Returning the call is exactly what callback scams want - it can connect you to expensive service lines or expose your number as active to further scammers.
Why do numbers like 07 3815 5729 keep ringing with no response?
This pattern typically indicates automated dialling systems testing which numbers are active. When someone answers (like the contributor who received the call from 0738155729), the system may attempt to connect to an operator or simply disconnect. It's a common tactic in callback scams and robocall campaigns.
Is 0738155729 a real Optus customer service number?
07 3815 5729 is allocated to Optus Networks in Queensland, but allocation alone doesn't confirm it's a legitimate customer service line. The silent call pattern reported for 0738155729 suggests it's being used for unwanted calling activity. Always verify Optus contact numbers independently via their official website rather than returning an unsolicited call.
What should I do if I keep receiving calls from 07 3815 5729?
Block the number immediately in your phone settings. Report the repeated silent calls from 0738155729 to ACMA at acma.gov.au and document the dates and times. If the calls escalate or you're concerned about data breach, also report to Scamwatch at scamwatch.gov.au.
Can I report this silent call pattern to stop calls from 07 3815 5729?
