Unknown Calls from 02 5300 7307
Two contributors have reported receiving calls from 02 5300 7307 (also written as 0253007307) without any message left behind. Both incidents involved missed calls where the caller made no attempt to leave voicemail or contact information, which is typical behaviour for unknown or automated callers testing active numbers.
The number is allocated as a local NSW service through Symbio Networks Pty Ltd, suggesting it could be a legitimate business line, a customer service number, or a spoofed caller using a local number to appear credible. Without additional context from the reports, it's difficult to determine the caller's intent.
Call Pattern for 02 5300 7307
Both reports of 0253007307 came through missed calls rather than answered conversations. The first report was logged on 11 February 2026, and a second similar incident occurred on 12 February 2026, suggesting possible repeated contact attempts within a short timeframe.
The absence of voicemail messages is notable. Legitimate businesses typically leave details about why they called, while scammers and robocalls often hang up silently to identify active phone numbers for later targeting or to avoid recording evidence of their call.

WRITE A REVIEWFrequently Asked Questions
Should I answer if 02 5300 7307 calls me?
It's safer to let unknown numbers like 0253007307 go to voicemail first. If the caller has a legitimate reason to reach you, they will leave a message explaining who they are and why they called. Since both reports of 02 5300 7307 involved calls with no voicemail, answering is unlikely to clarify the caller's identity.
Why do callers from 0253007307 not leave messages?
Silent calls without voicemail messages are common from robocalls, spam campaigns, and scammers testing whether a number is active. Legitimate businesses almost always leave a reason for calling. If 02 5300 7307 contacts you multiple times without explanation, it's reasonable to treat it as an unwanted call and block it.
Is 02 5300 7307 a scam number?
Based on available community reports, 0253007307 cannot be confirmed as a scam. The two reports simply document missed calls with no message. However, the pattern of repeated silent calls is suspicious. To determine if 02 5300 7307 is legitimate, search for the number online, check if you recognise the Symbio Networks provider, or contact the provider directly using contact details you find independently.
What does it mean that 0253007307 is a 'local service' number?
The allocation data shows 02 5300 7307 is registered as a local NSW service through Symbio Networks Pty Ltd. This indicates it's not a national 1800 number or international line. However, scammers can spoof local numbers to appear more credible, so allocation data alone doesn't confirm legitimacy. Always verify independently.
How many people have reported 02 5300 7307?

If 0253007307 continues to call without leaving messages, block the number in your phone settings. You can also report it to the Do Not Call Register (donotcall.gov.au) or ACMA (acma.gov.au).
