WRITE A REVIEWFrequently Asked Questions
Why would a caller claim I have an NBN problem when I don't have NBN?
Scammers using 0400 755 419 typically make broad claims hoping the recipient will either confirm details (revealing personal information) or panic and follow their instructions. If you don't have NBN, you've already identified the call as fraudulent. The contributor who reported 0400 755 419 recognized this immediately, which is the correct response.
What should I do if 0400755419 calls me?
Hang up immediately. Do not engage with the caller or provide any information. If 0400755419 calls again, block the number in your phone settings. You can also report the call to Scamwatch at scamwatch.gov.au or ACMA at acma.gov.au to help protect other Australians.
How do I verify a legitimate NBN issue if I have NBN?
Never trust unsolicited calls about NBN problems. Instead, contact NBN directly using the phone number on your NBN bill or visit nbnco.com.au. Legitimate NBN support will not call you demanding immediate payment or account details. If 0400 755 419 calls claiming to be NBN, it is a scam.
Can I report 0400 755 419 to my phone provider?
Yes. Since 0400 755 419 is a Telstra mobile number, you can report it to Telstra directly. However, the most effective reporting channels are Scamwatch (scamwatch.gov.au) and ACMA (acma.gov.au), which coordinate responses across multiple providers. Contributing to Reverseau also helps the community track this number.
Why did the caller hang up when challenged?
The caller from 0400 755 419 hung up because they rely on pressure and deception. Once challenged, they cannot maintain the false claim. This is typical behaviour for scammers operating from scripts who lack the flexibility to respond to informed pushback. It confirms the call was fraudulent.
Is 0400755419 the only scam number impersonating NBN?
No. Many numbers are used for NBN impersonation scams. However, reporting 0400755419 and other suspicious numbers to Scamwatch (scamwatch.gov.au), ACMA (acma.gov.au), and Reverseau helps track patterns and protect more Australians. Block any number that claims to be NBN without you initiating contact.
