One contributor has reported receiving a call from 04 0355 7418 (also written as 0403557418), an Optus mobile number.

Silent Calls and Callback Scams
Silent calls from call centre numbers like 0403557418 can be part of a callback scam strategy. In these schemes, the caller hangs up after you answer, hoping you will be curious enough to call the number back. Once you dial back, you may connect with a scammer operating a fake customer service line, often impersonating banks, tech support, or government agencies.
The fact that 04 0355 7418 came from an Optus mobile rather than a fixed business line makes it slightly unusual for a legitimate call centre, though this alone is not definitive proof of malicious intent.

WRITE A REVIEWFrequently Asked Questions
Why would someone call from 04 0355 7418 and say nothing?
Silent calls from numbers like 0403557418 are often part of callback scams where the caller hopes you'll ring back out of curiosity. Once you call back, you may reach a scammer posing as a bank or tech support. Alternatively, it could be an automated system testing if the number is active, or a misdirected call centre attempt. The one contributor who answered 04 0355 7418 experienced total silence, which is typical of these scenarios.
Should I call 0403557418 back if it's from a call centre?
No. Even though 04 0355 7418 appeared to come from a call centre, you should not call it back. Legitimate businesses will call again or leave a voicemail if they need to reach you.

Is 04 0355 7418 a known scam number?

Can Optus mobile numbers be used for scams?
Yes. While 04 0355 7418 is registered to Optus Mobile, scammers can spoof or misuse legitimate mobile numbers. A genuine Optus customer might not be the one making the call from 0403557418. If you believe the number has been compromised, you can report it to Optus and to ACMA at acma.gov.au.
