WRITE A REVIEWFrequently Asked Questions
Is 03 9003 1150 really calling from Telstra?
Probably not. One contributor reported this number claiming to be Telstra, but the technical profile - an overseas IP phone with call delay - is inconsistent with genuine Telstra calls, which originate from Australian networks. Always verify by calling Telstra directly using their official number 133 200 rather than returning calls from 0390031150.
What does it mean if 03 9003 1150 has an overseas IP delay?
The delay reported when answering 0390031150 is typical of VoIP (internet phone) calls originating overseas. This suggests the caller is using internet-based calling technology, often a sign of impersonation or spoofing, since legitimate Telstra calls use Australian telecommunications infrastructure.
Should I answer calls from 03 9003 1150?
No. If you don't recognise 03 9003 1150 (0390031150), let it go to voicemail. If it's a legitimate caller, they can leave a message. If the number calls repeatedly, block it through your phone settings or contact your provider.
What should I do if 03 9003 1150 claims there's a problem with my Telstra account?
Do not engage with the caller. Hang up immediately and contact Telstra directly using the phone number on your bill or their official line 133 200. Never give account details, passwords, or personal information to unexpected callers claiming to be 0390031150 or any Telstra representative.
Can I block 03 9003 1150 on my phone?
