Telstra Impersonation Reports for 03 7050 0433
Two contributors have flagged calls from 03 7050 0433 (also written as 0370500433), a local Victoria-based number allocated to Symbio Networks. One report involves impersonation of Telstra, while another describes silent call behaviour. The impersonation attempt is particularly notable because the caller claimed to represent Telstra but failed basic verification by getting the recipient's name wrong and targeting someone who isn't even a Telstra customer.
This mismatch suggests either poor data sourcing or a deliberate tactic to test whether recipients will engage. The caller's inability to correctly identify the person they were targeting is a red flag for scam activity masquerading as legitimate customer service.
What Callers from 03 7050 0433 Say
According to the impersonation report, the caller from 03 7050 0433 claimed affiliation with Telstra. However, the caller demonstrated insufficient knowledge about the recipient - not only did they mispronounce or misstate the recipient's name, but they also appeared unaware that the person was not a Telstra customer. This failure to match basic customer records is inconsistent with genuine Telstra representatives conducting account inquiries.
The second report describes a different behaviour pattern - a silent call where the recipient answered but heard only silence. When the caller did speak, they repeatedly said "hello" before disconnecting. This type of call is often associated with callback scams or robocall systems testing active numbers for future targeting.
Call Patterns and Timing
The two reports involving 0370500433 show different patterns. The Telstra impersonation call came through in February 2026, while the silent call occurred in May 2025. Both were answered calls, suggesting the number has been actively dialling. The silent call pattern, in particular, is consistent with systematic number testing rather than a one-off misdial.
One contributor noted the silent call involved repeated "hello" statements before disconnection - a common signature of automated systems or callback scam infrastructure probing for engaged numbers.

WRITE A REVIEWFrequently Asked Questions
Why would someone call from 03 7050 0433 claiming to be from Telstra if they don't even know I'm a customer?
Scammers often source phone numbers from data brokers or public listings rather than legitimate customer databases. The caller from 03 7050 0433 may have been mass-dialling or testing numbers, which is why they had no accurate customer information. When they got your name wrong and discovered you weren't a Telstra customer, it revealed their lack of legitimate access to Telstra's actual customer records. This mismatch is a strong indicator of impersonation scam activity.
What does it mean when someone calls from 0370500433 and just stays silent?
Silent calls from 0370500433 are often made by automated robocall systems or scammers testing whether your number is actively monitored. When the caller on the other end finally speaks and only says "hello" before hanging up, it typically means the system detected an answer and is logging your number as active. This information is then sold to other scammers or used for callback scams later. The repeated "hello" from 0370500433 matches this pattern exactly.
Is 03 7050 0433 a real Telstra number?
No. The number 03 7050 0433 is allocated to Symbio Networks, a Victorian internet service provider, not to Telstra. This confirms that anyone claiming to call from Telstra using 03 7050 0433 is impersonating and using a spoofed or hijacked number. Telstra customer service calls come from Telstra-owned numbers, not from local provider allocations. If Telstra needs to contact you, verify by calling their official support line.
Should I call back 0370500433 to ask who they are?
No. Do not return calls to 0370500433 or any unknown number claiming to represent a service provider. Calling back confirms your number is active and monitored, which is exactly what silent call scammers want. Instead, if you need to contact Telstra or verify a call, use the contact details on your official bill or visit their official website directly. Never dial a number provided by an unsolicited caller.
What should I do if 03 7050 0433 calls me multiple times?
Block 03 7050 0433 immediately in your phone's call settings. Most Australian phones allow you to block numbers and send them directly to voicemail. After blocking, report the repeated calls to ACMA at acma.gov.au with dates and times. If the caller from 03 7050 0433 is claiming to represent Telstra, also report to Telstra's fraud team directly. Document each call attempt as evidence of harassment.
Could the silent call from 0370500433 have been accidental?
Unlikely. A single misdial might result in silence, but the pattern from 0370500433 involved the caller repeatedly saying "hello" before disconnecting. This is deliberate behaviour consistent with robocall systems or callback scam infrastructure. Accidental calls usually result in immediate apology and disconnection, not repeated "hello" statements. The timing and method suggest systematic number testing rather than an honest mistake.
