WRITE A REVIEWFrequently Asked Questions
Why would someone call 08 7084 6220 and not say anything?
Silent calls are typically used by scammers to verify that your phone number is active and answered by a real person. The caller from 0870846220 hung up after you answered, which is a common tactic to build lists of confirmed active numbers for follow-up callback scams or impersonation attempts.
Should I call back a silent call from 08 7084 6220?
No. Never return a call from 0870846220 after a silent call. Returning the call confirms your number is monitored and can lead to follow-up scam attempts. Block the number instead and report it to ACMA.
Is 08 7084 6220 a real Optus number?
The number 0870846220 is allocated to Optus Networks in South Australia, but scammers frequently spoof legitimate provider numbers to appear credible. The silent call pattern suggests misuse rather than a legitimate Optus inquiry. Contact Optus directly via their official website if you're concerned.
What should I do if 08 7084 6220 calls me repeatedly?
Block 0870846220 in your phone's call settings, report to ACMA at acma.gov.au, and avoid answering if the number appears again. Repeated calls after a silent attempt may indicate escalating scam activity.
Could this silent call from 08 7084 6220 lead to other scams?
Yes. Silent calls from 0870846220 are often the first step in callback scams or targeted impersonation attempts. Scammers use them to confirm active numbers before calling back with spoofed caller IDs claiming to be banks, the ATO, or other authorities.

Report to ACMA at acma.gov.au (they investigate nuisance calls), Scamwatch at scamwatch.gov.au (if you suspect follow-up scam activity), and the Do Not Call Register at donotcall.gov.au. You can also share your experience on Reverseau to help other Australians.
