WRITE A REVIEWFrequently Asked Questions
What is a silent call and why would 03 7057 0780 use this tactic?
A silent call is when someone rings your number but hangs up or remains silent when you answer. 03 7057 0780 (0370570780) may use this tactic to test whether your number is active before attempting a scam or to provoke you into calling back a premium or scam number. The contributor who answered 03 7057 0780 experienced exactly this - they greeted the caller, but the line went silent and disconnected.
Should I call back a number like 03 7057 0780 if I miss a call?
No. Do not call back 03 7057 0780 or any unknown number that leaves no voicemail message. Silent calls and missed calls without messages are often callback scams designed to trick you into returning the call. One contributor received a missed call from 0370570780 with no message - this is a red flag.
Is 03 7057 0780 definitely a scam?
The reports for 03 7057 0780 (0370570780) show silent calling and missed calls with no voicemail, which are common scam tactics. However, with only 2 reports, we cannot definitively confirm this number is used for scams - it could also be a legitimate business with a faulty dialling system. Blocking the number is a safe precaution if it calls you repeatedly.
What should I do if 03 7057 0780 keeps calling me?
If you continue receiving calls from 03 7057 0780, block the number using your phone's call-blocking feature. Do not answer or return the call.

Can I find out who owns the number 03 7057 0780?
03 7057 0780 (0370570780) is allocated to Symbio Networks Pty Ltd, a Victorian service provider. However, this allocation does not confirm who is making the calls - the number may have been spoofed, compromised, or reassigned. The silent calling behaviour reported suggests the number may not be used legitimately at present.
What is the difference between a silent call and a missed call?
A silent call occurs when you answer the phone and the caller is on the line but says nothing before hanging up - as happened to one contributor who answered 03 7057 0780 and heard silence. A missed call is when your phone rings but you don't answer, and no voicemail is left - like the January missed call from 0370570780. Both patterns suggest callback scam testing.
