Silent Call Reports for 0421 216 760
A contributor has reported receiving repeated calls from 0421 216 760 (also written as 0421216760) with no voicemail messages left. The caller does not identify themselves and the calls appear deliberate rather than accidental, as the number continues to ring despite never receiving a response or answer.
The number is registered as an Optus mobile service. Without clear identification or messaging, the pattern of repeated silent calls from 0421216760 suggests either a callback scam setup, a telemarketer using autodial, or an abandoned call attempt. The contributor has already blocked 0421 216 760 to prevent further contact.
Report Patterns
The single report about 0421 216 760 comes from missed call activity with no voicemail left behind. This behaviour is characteristic of several types of unwanted calls: robocall systems that disconnect when voicemail is reached, callback scams that rely on return calls to trigger charges, or telemarketing campaigns using automated diallers that don't connect to a live operator.
What to Do If You Receive a Call from 0421 216 760
If 0421216760 calls you:
- Do not: Answer the call, return any missed call, or call back to see who it was
- Do: Let it go to voicemail, block the number immediately in your phone settings, and ignore if the number appears again
- If it persists: Report to ACMA at acma.gov.au and consider filing a complaint with your phone provider (Optus in this case)
Silent or repetitive calls that leave no message are a common harassment tactic. Do not engage by calling back, as this may confirm your number is active and lead to more calls.

WRITE A REVIEWFrequently Asked Questions
What does it mean if 0421 216 760 keeps calling but never leaves a message?
Repeated silent calls from 0421216760 typically indicate either a robocall system that disconnects when it reaches voicemail, a callback scam waiting for you to return the call, or an automated telemarketing dialler. The fact that no message is left suggests the caller is not interested in communicating - they're testing if your number is active or hoping you'll call back.
Should I call back 0421 216 760 to find out who's calling?
No. Do not call back 0421216760 under any circumstances. Calling back confirms your number is active and monitored, which encourages more calls. If the caller had legitimate business with you, they would leave a voicemail message. Returning the call may also expose you to unexpected charges or further unwanted contact.
Is 0421216760 a scam number?
The single report about 0421 216 760 does not provide enough detail to confirm a scam, but the behaviour of repeatedly calling without leaving a message is suspicious. The number is registered to Optus mobile service. If you're concerned, block the number and report it to ACMA at acma.gov.au if the calls continue.
How do I block 0421 216 760 on my phone?

What should I do if 0421216760 continues to call after I block it?
If 0421 216 760 continues calling from different numbers or after blocking, report it to ACMA (acma.gov.au) and lodge a Do Not Call Register complaint at donotcall.gov.au. Contact your phone provider (Optus) for additional support and request network-level blocking if harassment persists.
