Robocall Reports for 02 7820 4904
One contributor has reported receiving a robocall from 02 7820 4904 (also written as 0278204904). The call arrived as an automated voicemail message presenting a language selection prompt, then switched to Mandarin-language content. This pattern is consistent with mass-dialled robocall campaigns that use language options to target diverse populations.
The number is allocated to Symbio Networks Pty Ltd, a local service provider in New South Wales. Robocalls of this type typically attempt to reach large contact lists with minimal targeting, often to deliver unsolicited offers or gather engagement metrics for further marketing campaigns.
What the Robocall from 02 7820 4904 Delivered
The automated message from 0278204904 presented an initial prompt: "update online press 1 for English 2 for Chinese." After the contributor's interaction, the call switched to Mandarin-language content. The use of language selection suggests the campaign targets both English and Mandarin-speaking Australians, likely with different messaging for each language group.
The "update online" framing is typical of robocall phishing attempts, which often create false urgency around account updates, payment information, or service activation to prompt recipients to engage further or visit external links.

This suggests the system attempted contact when the line was unavailable, and the automated message was left as a recorded prompt.

WRITE A REVIEWFrequently Asked Questions
What happens if I press 1 or 2 on a robocall from 02 7820 4904?
Pressing any keypad option confirms your number is active and monitored by a live person, which adds your contact to targeted call lists for future campaigns. The robocall from 0278204904 uses the language selection prompt specifically to capture responses. Do not engage with any keypad request.
Why did 02 7820 4904 offer both English and Mandarin options?
Robocalls targeting 0278204904 often segment audiences by language to increase engagement rates. Offering language choice makes the call appear more legitimate and allows the campaign to deliver tailored phishing or marketing content based on language preference.
Is 0278204904 a real business number?
The number 02 7820 4904 is allocated to Symbio Networks Pty Ltd, a local service provider in New South Wales. However, robocalls can spoof or misuse legitimate business numbers. The automated message and language selection format strongly indicate this is an unsolicited robocall campaign, not a legitimate business contact.
What should I do if I already responded to the robocall from 02 7820 4904?
If you pressed any option or engaged with the 0278204904 robocall, monitor your accounts for suspicious activity, especially banking and payment services. Change passwords for critical accounts if you entered any information. Block 02 7820 4904 immediately and report the call to ACMA at acma.gov.au.
Can I report robocalls to the Do Not Call Register?
Yes. File a complaint about 02 7820 4904 (0278204904) at donotcall.gov.au if you have received multiple calls. The Do Not Call Register handles persistent robocall violations, though initial reports should also go to ACMA for faster action on active campaigns.
Will blocking 0278204904 stop future robocalls?
Blocking 02 7820 4904 will prevent that specific number from reaching you, but robocall campaigns often use multiple numbers in sequence. Blocking is an important first step, but also report to ACMA and the Do Not Call Register to help shut down the underlying campaign.
