What Callers from 04 0803 8453 Have Done
Contributors report mixed contact patterns from this Telstra number.

WRITE A REVIEWFrequently Asked Questions
Why would a caller from 04 0803 8453 hang up without speaking?
Silent calls from 0408038453 are often used to test whether your number is active and monitored. If you don't respond or hang up immediately, scammers may note your number as unresponsive and move on, or they may use the confirmed active status for more targeted follow-up attempts later. Never call the number back, as this confirms activity.
What should I do if 04 0803 8453 asks for money when I answer?
Hang up immediately. Do not provide any personal information, bank details, or payment information to 0408038453. Legitimate organisations do not call requesting money directly without identifying themselves clearly and providing verifiable contact details. Block the number and report it to ACMA at acma.gov.au.
Is 04 0803 8453 a scam because it's a VOIP number?
Not all VOIP numbers are scams, but scammers often use VOIP services because they're difficult to trace and can mask the caller's real location. One contributor described 0408038453 as a dodgy VOIP asking for money, which is a strong indicator of fraudulent activity. Legitimate businesses identify themselves clearly.
Should I call back 0408038453 if I missed the call?
No. Do not call back 04 0803 8453 if you don't recognise the number and they left no voicemail. Calling back confirms your number is active and monitored, which scammers use to prioritise numbers for future targeting. If it's important, they'll leave a message or you can verify the number independently.
How do I block 04 0803 8453 on my phone?
On most Australian phones, open your recent calls list, find 0408038453, and select 'Block' or 'Block number'. Different phone models have slightly different processes: iPhone users can swipe left on the call and select Block, while Android users can tap and hold the number and select Block. Report the number before blocking for community benefit.
What if 04 0803 8453 calls back after I block it?
Scammers may use multiple numbers or access to the same network to continue contact. If 0408038453 or similar numbers keep calling after blocking, report the pattern to ACMA (acma.gov.au) and Scamwatch (scamwatch.gov.au). Consider reporting to your phone provider, Telstra, if the calls continue from this Telstra number.
