Impersonation and Phishing Reports for 04 5881 9840
Three contributors have flagged calls and SMS messages from 04 5881 9840 (also written as 0458819840) for suspicious behaviour involving impersonation and phishing attempts. The reports describe a pattern where the caller impersonates a recruiter during phone calls, while text messages attempt to establish familiarity before directing recipients to suspicious links.
The mobile number, allocated to Telstra Limited, has been reported for tactics designed to build trust before extracting personal information or financial details. Contributors note the caller's initial approach appears casual and friendly, which may be an attempt to lower the recipient's guard before escalating the scam.
What Callers from 04 5881 9840 Say
One contributor received a call from 04 5881 9840 where the caller pretended to be a recruiter. The impersonation tactic suggests the caller may be attempting to gather employment or personal details under false pretences, or to build rapport before requesting sensitive information.
On the SMS side, contributors report receiving text messages from 0458819840 that open with casual, friendly language such as 'how you been' or 'hello'. These messages are designed to appear as though they're from someone the recipient knows. One contributor correctly identified the pattern as phishing - the friendly tone is likely an attempt to get the recipient to engage, trust the sender, and click embedded links without suspicion.
Report Patterns and Timing
The reports span early November 2025. One contributor received the friendly SMS message on 1 November, the same day as the recruiter impersonation call. A second SMS with similar friendly phrasing was also reported on 1 November, suggesting the caller may be working through contact lists or targeting multiple people on the same day. A third report arrived later, on 9 November, with another suspicious SMS.
The mixed communication channels - both calls and SMS - indicate the number is being used opportunistically to reach targets in whatever way possible. The timing gaps suggest this is an active campaign rather than isolated incidents.

WRITE A REVIEWFrequently Asked Questions
Should I answer if 04 5881 9840 calls me about a job opportunity?
No. If 04 5881 9840 calls claiming to be a recruiter, do not engage. Legitimate recruiters provide verifiable company details and always allow you to independently confirm their identity. Callers from 0458819840 who impersonate recruiters are likely phishing for personal or employment information to use in identity fraud or further scams.
What should I do if I already clicked a link from a text by 0458819840?
Stop immediately and do not enter any information. Change your passwords for email and banking accounts from a different device. Monitor your accounts for unauthorised activity. Contact your bank if you entered financial details. Consider running antivirus software on your device. Monitor your credit report for suspicious applications. Report the link to cyber.gov.au and your phone provider as soon as possible.
Why does the SMS from 04 5881 9840 seem friendly if it's phishing?
Friendly, casual messages are a deliberate phishing tactic. By appearing to know you or using natural conversation starters like 'how you been', the sender lowers your suspicion and makes you more likely to click links or engage. This is social engineering - the friendliness is fake and designed to manipulate you into trusting the sender.
Can I block 04 5881 9840 on my phone?
Yes. On most Australian mobile phones, you can block 0458819840 directly through your phone's settings or contact list. Most providers also allow you to block numbers through their customer portal or by calling their support team. Blocking will prevent the number from calling or texting you, but it won't stop the caller from using other numbers.
Is 04 5881 9840 definitely a scam or could it be someone I know?
Community reports from 0458819840 describe impersonation and phishing tactics, which are deliberate scam techniques. If you received a casual SMS or recruiter call from 04 5881 9840 and you're unsure, contact the person directly using a number you know is correct (from your contacts or their official social media). If they didn't send the message, it's definitely a scam.
What happens if I report 04 5881 9840 to ACMA?
ACMA investigates complaints about phone scams, SMS phishing, and telecommunications misuse. While individual reports help build a pattern, ACMA's primary focus is enforcement against large-scale scam operations.
