Telstra Impersonation Reports for 03 8000 4457
Two contributors have flagged calls from 03 8000 4457 (also written as 0380004457) for suspicious activity. At least one report describes a caller deliberately impersonating Telstra, a common tactic used in telecom scams targeting Australian customers.
The number is allocated to Symbio Networks Pty Ltd, a local service provider in Victoria, but this allocation does not guarantee the calls are legitimate. Scammers frequently spoof or misuse local numbers to appear credible.
What Callers from 03 8000 4457 Do
One contributor who answered a call from 03 8000 4457 reported that the caller claimed to be from Telstra. This impersonation tactic is typically used to manipulate victims into revealing account details, paying fake bills, or authorising account changes.
A second report describes a different call pattern: the caller hung up without introducing themselves or explaining the reason for the call. Silent or abrupt hang-ups from numbers like 0380004457 may indicate callback scams, where the caller hopes you'll return the missed call and be connected to a premium line or scam operation.
What to Do If You Receive a Call from 03 8000 4457
If 03 8000 4457 calls you:
- Do not: Answer if you don't recognise the number; share account details, passwords, or payment information; trust caller ID alone as proof of identity
- Do: Let it go to voicemail; independently verify any urgent claims by calling Telstra directly on their official number (1300 300 630); block the number immediately if you receive repeat calls from 0380004457
Telstra will never ask for passwords, PIN numbers, or bank details over an unsolicited call. If the caller becomes aggressive, abusive, or makes threats, hang up immediately and do not re-engage.
