Chinese Robocall Scam Reports for 02 5740 7318
Two contributors have reported receiving missed calls from 02 5740 7318 (also written as 0257407318) with automated Mandarin voicemails. Both calls went unanswered, leaving only pre-recorded messages with no caller identification or explanation. The voicemails are consistent with known Chinese robocall scams that target Australian phone numbers indiscriminately.
The number 02 5740 7318 is allocated to a local service provider (Symbio Networks) in NSW, but the calls appear to be spoofed or routed through legitimate infrastructure to mask their origin. Contributors describe the messages as brief and automated, featuring basic Mandarin greetings such as "ni hao" with no follow-up context or request for action.
Robocall Characteristics from 02 5740 7318
The calls from 0257407318 are fully automated with no live operator. One contributor noted the voicemail appeared "consistent with known Chinese robocall scams," indicating the pattern matches documented campaigns targeting Australian households and businesses. No personal information was disclosed by either contributor, as both calls were missed and went to voicemail.
The lack of caller identification is a key red flag. Legitimate organisations always identify themselves when leaving voicemails. The automated nature of the message from 02 5740 7318, combined with the absence of any business context or purpose, strongly suggests this is a mass-dialling campaign with no genuine communication intent.
Report Patterns and Timing
Both reports of calls from 02 5740 7318 occurred within a 24-hour window in early April 2026, with one report submitted today (2 April) and another on 1 April. This clustering suggests either a surge in activity from this number or a coordinated robocall campaign targeting multiple Australian numbers simultaneously.
The voicemail-only nature of both reports is significant. Neither contributor answered the call, so they avoided any risk of engagement or callback traps. This is actually protective behaviour, as returning a robocall to 0257407318 could confirm the number is active and monitored, potentially adding it to callback lists for future scams.

WRITE A REVIEWFrequently Asked Questions
Why did I receive a Mandarin voicemail from 02 5740 7318?
The call to your number from 02 5740 7318 (0257407318) is part of a mass robocall campaign. These automated systems dial thousands of numbers without targeting specific individuals. The Mandarin message is a generic recording with no personalisation, suggesting the caller has no knowledge of you or your phone number. You were likely contacted at random.
Is 02 5740 7318 a real business number?
No. While 0257407318 is allocated to Symbio Networks (a legitimate NSW provider), scammers frequently spoof or hijack real phone numbers to appear local and trustworthy. The automated Mandarin voicemail with no identification strongly indicates this is a spoofed call, not genuine communication from the provider itself.
What happens if I call 02 5740 7318 back?
Do not call 0257407318 back. Returning the call confirms your number is active and monitored, which adds you to callback lists for future scam campaigns. Robocalls from 02 5740 7318 may also trigger premium-rate charges or connect you to dangerous follow-up scams. Ignore the voicemail entirely.
Should I listen to the voicemail from 02 5740 7318?
No. Delete the voicemail from 0257407318 without listening. Some robocalls use caller engagement (replaying, pressing buttons) as a trigger to escalate campaigns or confirm your number is engaged. The safest action is to block 02 5740 7318 and discard the message.
How do I block 02 5740 7318 on my phone?
On most Australian phones, open your call history, find the entry for 02 5740 7318 (0257407318), and select "Block this caller" or "Add to blocklist." You can also contact your carrier (like Optus, Vodafone, or Telstra) to request network-level blocking of 0257407318, which prevents the call from reaching your phone entirely.
