Silent Calls and Personal Information Probing from 02 5350 6897
Five contributors have reported suspicious activity from 02 5350 6897 (also written as 0253506897), a local NSW number allocated to Symbio Networks. The pattern is concerning: callers either hang up without leaving a message, or call and reference the recipient's family members by name despite being from an unfamiliar number. This combination suggests potential social engineering or targeted information gathering.
Two separate reports about 0253506897 specifically mention that the caller knew the recipient's daughter's name, raising red flags about how this information was obtained. Neither report confirms the caller actually claimed to be the daughter, but the use of personal details in a cold call is a recognised social engineering tactic used to build false trust before requesting sensitive information or money.
What Callers from 02 5350 6897 Do
Contributors describe two distinct patterns from calls originating at 02 5350 6897. The most alarming reports involve missed calls where the caller ID or voicemail greeting mentions a family member's name - specifically a daughter in multiple cases. When recipients checked back on these calls, they found no legitimate connection to that family member.
A second pattern involves silent calls: the number rings once or twice, then disconnects with no voicemail left behind. One contributor noted the call from 02 5350 6897 "rang once then hung up, no voicemail." Another described similar behaviour: "rang once and bailed, no voicemail." These brief connection patterns are typical of callback scams or number-testing operations.
One report also mentioned fundraising-related activity, suggesting 0253506897 may be testing multiple approaches to determine which tactics generate responses from recipients.
Call Patterns and Timing
Reports span from November 2025 through early March 2026, indicating ongoing activity from this number over several months. The calls arrive at different times: one report from 02 5350 6897 came in at 1:13 AM (early morning), while others occurred during business hours (8:37 AM, 10:44 AM, 11:07 AM). The varied timing suggests either automated dialling systems or multiple call attempts targeting different recipients.
Most calls to 0253506897 were not answered by recipients, with the number leaving no voicemail. This pattern - missed calls with no message - is consistent with list-testing operations where callers verify which numbers are active before escalating contact attempts.
What to Do If You Receive a Call from 02 5350 6897
If 02 5350 6897 calls you:
- Do not: Answer if it's an unknown number, engage with callers who reference your family members, or provide any personal or financial information
- Do: Let the call go to voicemail, verify the caller's identity through official channels before responding, check with your family member directly if the caller claims to represent them
- Do: Block the number if calls repeat, note the date and time of each call for reporting purposes
If a caller from 02 5350 6897 mentions your family member by name but claims to be calling on their behalf, hang up immediately and contact that family member directly using a known phone number. Scammers often use personal details to appear legitimate.
Silent calls from 0253506897 should be treated as potential callback scams. Do not return the call, as connecting may confirm your number is active and lead to targeted follow-up attempts.

WRITE A REVIEWFrequently Asked Questions
Why would a caller from 02 5350 6897 mention my family member's name?
Two contributors reported that 02 5350 6897 (0253506897) referenced their daughter by name in the call ID or voicemail, despite being an unfamiliar number. This is a social engineering tactic - using personal details to create false credibility and lower your guard before requesting sensitive information, money, or financial access. Legitimate callers representing your family member would contact you from a known number or arrange contact in advance.
What does it mean when 0253506897 calls and hangs up immediately?
Two reports describe 02 5350 6897 ringing once or twice then disconnecting with no voicemail. This pattern is typical of callback scams or list-testing operations - callers confirm your number is active and monitored, or attempt to trigger a callback to a premium service. Do not return calls to 0253506897 even if curious about who called.
Is 02 5350 6897 a legitimate business number?
02 5350 6897 (0253506897) is allocated as a local NSW service through Symbio Networks, but allocation to a legitimate provider does not guarantee legitimate use. Numbers can be spoofed or misused. The pattern of silent calls, personal information references, and reports about fundraising scams from 0253506897 suggests the number is being used for suspicious purposes regardless of its registered provider.
Should I answer calls from 02 5350 6897 to ask who they are?
No. Contributors who didn't answer 02 5350 6897 avoided engagement with the suspicious activity. If you do answer and the caller mentions your family member or requests information, hang up immediately and contact your family member or the relevant organisation directly using a known, official phone number. Do not rely on contact details provided by a caller claiming to be from 0253506897.
What should I do if 0253506897 mentions my daughter by name?
This is a red flag. Hang up immediately without providing any information. Contact your daughter directly on a number you already have to confirm she did not call or authorise anyone to call on her behalf. If 02 5350 6897 continues calling and referencing your family members, report the activity to ACMA (acma.gov.au) and consider blocking the number. This pattern suggests data collection or targeted social engineering.
How do I block 02 5350 6897 on my phone?
On most Australian phones: add 02 5350 6897 (0253506897) to your contacts, then mark as blocked or spam. iPhone users can use the 'Block this Caller' option when viewing the number in recent calls or voicemail.
