Two contributors have reported calls from 03 9003 1186 (also written as 0390031186) involving suspicious activity. One report describes a caller impersonating a Telstra representative, while another details an automated robocall with no business identification.

What Callers from 03 9003 1186 Say

The second report about 03 9003 1186 involved an automated recording about customer service. No business name or identifying information was provided in the robocall, making it impossible for the recipient to verify the caller's legitimacy. The automated nature suggests a mass-dialling operation.

What to Do If You Receive a Call from 03 9003 1186
If 03 9003 1186 calls you:
- Do not: Follow instructions to change network settings, disable security features, or provide remote access to your device

- Do: Contact Telstra directly using the number on your bill or official website to verify any claims about your account

Callers requesting remote access or technical changes are almost always attempting to compromise your device security. The caller from 03 9003 1186 persisting after being questioned is classic scam behaviour.

WRITE A REVIEWFrequently Asked Questions
What does it mean if a caller claims to be from Telstra and asks me to change my IP address?
This is a scam tactic. The contributor who received a call from 03 9003 1186 reported exactly this scenario. Telstra support will never ask you to change IP settings without proper verification, and changing settings based on caller instructions gives scammers remote access to your network. Always hang up and contact Telstra directly using the number on your bill.
Should I call back a number that only left a robocall message from 0390031186?
No. One contributor reported calling back 03 9003 1186 only to hear an automated customer service recording with no business name. Calling back unknown robocall numbers can confirm your number is active and lead to more calls. Block 0390031186 instead and report it to ACMA.
How can I verify if a caller really works for Telstra?
Never use the phone number provided by the caller. If someone calls claiming to be from Telstra, hang up and call Telstra directly using the number on your bill, your account statement, or the official Telstra website. The caller from 03 9003 1186 continued pushing despite resistance, which is a sign they were not legitimate.
What should I do if 03 9003 1186 keeps calling me?
Block the number immediately on your phone. If calls continue from the same or similar numbers, report them to ACMA (acma.gov.au) and Scamwatch (scamwatch.gov.au). The contributor who received the initial impersonation call from 0390031186 blocked the number after hanging up, which is the correct response.
Why do scammers impersonate Telstra specifically?
Telstra is Australia's largest telecommunications provider, so claiming to represent them sounds credible to many people. The caller from 03 9003 1186 used this trusted brand name to justify requests for network access that would normally raise alarm bells. Always independently verify any technical support claims, regardless of which company the caller claims to represent.
Is my device compromised if I received a robocall from 0390031186?
Simply receiving an automated robocall from 03 9003 1186 does not compromise your device. However, if you provided any information or allowed remote access, your security may be at risk. One contributor's experience with a Telstra impersonation call from this number highlights why you should never grant access based on unsolicited calls.
