Silent Call Risks
Repeated calls without voicemail messages may indicate callback scams, where returning the call connects you to premium services, recorded lines, or unwanted subscription services. Even a brief connection can result in unexpected charges on your phone bill.
Some silent calls are also generated by autodiallers testing for active numbers, which then get sold to scammers or added to cold-calling lists. Avoid returning calls from 0421 612 090 unless you initiated contact with that number.

WRITE A REVIEWFrequently Asked Questions
Why would someone call 0421 612 090 without leaving a message?
Repeated calls without voicemail messages often indicate callback scams or autodiallers. Scammers use these tactics to prompt you to return the call to premium numbers, recorded services, or subscription traps. The fact that 0421612090 called on consecutive days without leaving a message fits this pattern. Never return calls from unknown numbers.
Is 0421 612 090 definitely a scam?
With one report mentioning silent calls, we cannot confirm 0421612090 is a scam. The intent remains unclear from the single report available. However, the pattern of repeated calls without messages is suspicious. If the number contacts you again, document the calls and block it. Contribute your report to help identify the caller.
What should I do if 0421 612 090 keeps calling me?
If 0421612090 continues to call without leaving messages, block the number immediately through your phone's settings. Do not return the call under any circumstances. Report the activity to ACMA at acma.gov.au, and consider registering with the Do Not Call Register at donotcall.gov.au. Let Reverseau know about your experience with 0421 612 090.
Could 0421 612 090 be a legitimate business trying to reach me?
Legitimate businesses and organisations leave voicemail messages or send SMS notifications explaining the reason for their call. A genuine caller would not repeatedly contact you from 0421612090 without ever leaving a message or identifying themselves. The pattern of silent calls suggests the caller has something to hide.
Will I be charged for returning a call from 0421 612 090?
Returning a call to 0421612090, an Optus mobile number, should not incur unusual charges unless the call is diverted to a premium service or expensive international line. However, callback scams sometimes use this tactic. To be safe, do not return calls from 0421 612 090 unless you initiated contact with that person. Check your phone bill regularly.
How can I stop receiving calls from 0421 612 090?
Block 0421612090 directly on your phone using your device's call-blocking feature. Most phones allow you to block contacts or entire numbers. Register your number with the Do Not Call Register at donotcall.gov.au to reduce unwanted calls. If calls from 0421 612 090 persist, report them to ACMA and provide screenshots of missed call logs as evidence.
