WRITE A REVIEWFrequently Asked Questions
Why does 04 8391 0364 keep calling but never leave a message?
The contributor's experience with 0483910364 suggests this is deliberate behaviour. Callers using nuisance tactics often contact multiple numbers without messaging because their goal is to prompt a return call rather than actually communicate. Returning such calls confirms your number is active and may lead to further contact or potential charges.
Should I answer if 04 8391 0364 calls again?
No. The safest approach is to let 0483910364 go to voicemail. If the caller has a legitimate reason to contact you, they will leave a message. Since the contributor reported no messages from 04 8391 0364 despite a full week of calls, answering is unlikely to resolve anything and may intensify the nuisance.
Is 0483910364 a scam or just annoying?
Based on the single report about 04 8391 0364, it appears to be nuisance calling rather than a scam that solicits money or personal information. However, repeated unanswered calls are a common tactic to generate curiosity prompting a return call, which can be exploited further. Blocking 0483910364 is the best defence.
Can I block 04 8391 0364 on my phone?
Yes. Most modern phones allow you to block numbers directly. On iPhone, open the call log, find 04 8391 0364, tap the 'i' icon, and select 'Block this Caller'. On Android, open Phone, long-press 0483910364, and select 'Block number'. This prevents 04 8391 0364 from reaching you further.
Who provides the 04 8391 0364 number?
04 8391 0364 is registered to Optus Mobile Pty Limited, an Australian mobile phone provider. The fact that 0483910364 is a mobile number suggests the caller could be using a personal or spoofed Optus account, making it harder to trace than a fixed business line.
What should I do before blocking 04 8391 0364?
Document the dates and times of calls from 0483910364 in case you need evidence for a formal complaint. Take screenshots or keep a written log. This information is valuable when reporting to ACMA or supporting a Do Not Call Register complaint about 04 8391 0364.
