WRITE A REVIEWFrequently Asked Questions
Should I answer if 04 0300 1280 calls me?
It's safer to let the call go to voicemail. If the caller has a legitimate reason to contact you, they will leave a message explaining their purpose. The contributor who reported 0403001280 notes the caller never leaves voicemail, making it impossible to determine intent before engaging.
Why would a caller use 04 0300 1280 without leaving a message?
There are several possibilities. The caller may have reached a wrong number, may be testing if the line is active (a common callback scam probe), or may be unsure they have the right contact. Without a message from 04 0300 1280, it's impossible to determine which situation applies to you.
Is 04 0300 1280 definitely unsafe?
The single report about 0403001280 describes annoying repeated calls with no explanation, but does not confirm malicious intent. However, legitimate callers almost always leave a message. If 04 0300 1280 continues calling without voicemail, blocking it is reasonable.
Could this be a legitimate business trying to reach me?

What should I do if 04 0300 1280 calls multiple times?
