WRITE A REVIEWFrequently Asked Questions
Why would someone call 0403 123 875 and hang up without speaking?
Silent calls are typically used to verify that a phone number is active and answered by a real person. Callers use this information to prioritise numbers for follow-up scam attempts. The contributor who received the call from 0403123875 experienced this verification tactic firsthand when the caller disconnected immediately after connection.
Is 0403 123 875 definitely a scam if it's a silent call?
A single silent call from 0403123875 indicates testing behaviour rather than an immediate scam attempt. However, silent calls are a known precursor to scam campaigns. If you receive follow-up calls from 0403 123 875 or similar numbers with aggressive claims, this initial silent call was likely verification for later targeting.
Should I call back 0403123875 if they called me?
No. Do not return calls to 0403123875 or any unknown number that hangs up silently. Returning the call confirms your number is active and monitored, which encourages more contact attempts. Hanging up without response is the correct action when 0403 123 875 calls.
What should I do if 0403 123 875 calls multiple times?
If you receive repeated calls from 0403123875, block the number immediately in your phone settings. Report the repeated calls to ACMA at acma.gov.au and your mobile provider Optus. Register your number with the Do Not Call Register at donotcall.gov.au to reduce future unwanted contact.
Can I block 0403 123 875 on my Optus phone?
Yes. Contact Optus customer service or use the Optus mobile app to block 0403123875 at the network level. You can also block the number directly in your phone's settings. Network-level blocking through Optus prevents the call from reaching your phone entirely, which is more effective than phone-level blocking.
Is the silent call from 0403123875 related to other scam numbers?
With only one report for 0403 123 875, we cannot confirm links to other scam campaigns. However, silent call patterns are common across many scam operations. If you experience silent calls from multiple numbers, this suggests coordinated verification testing. Report all instances to ACMA and contribute to Reverseau to help identify patterns.
