NBN Impersonation Scam Reports for 07 2143 6105

Eight contributors have reported calls from 07 2143 6105 (also written as 0721436105), with four reports specifically identifying this number as a scam. The common thread across multiple reports about 0721436105 is impersonation of Australian telecommunications providers, particularly the National Broadband Network (NBN) and Telstra. Contributors report callers claiming their internet service faces imminent disconnection due to suspicious activity or security breaches.

What distinguishes these reports is the use of AI-generated voices to deliver the scam pitch. One contributor specifically noted the artificial nature of the voice was "a bit of a give away," indicating the caller used robotic or synthesised speech rather than a live person. This automated approach aligns with mass-calling operations designed to reach as many households as possible with minimal human labour.

What Callers from 07 2143 6105 Claim

Contributors report consistent messaging from calls originating on 07 2143 6105. The primary claim involves a fabricated security issue: callers state the recipient's internet line or IP address has encountered unusual or suspicious activity requiring immediate action. One contributor described the specific claim as an "IP address has changed from private to public" scam, a known social engineering tactic targeting home internet users.

Reports about 0721436105 indicate callers impersonate legitimate service providers. One contributor received a call where the caller claimed affiliation with Telstra and referenced "unusual activity on my internet." Another contributor reported NBN impersonation, with the caller warning the internet would be "closed down due to suspicious activity." When challenged, one caller from 07 2143 6105 hung up immediately when asked which office they were calling from, suggesting difficulty maintaining the false identity under scrutiny.

The urgency tactic features prominently in reports. Contributors are pressured to act immediately to prevent service disconnection, a common element in tech support scams designed to bypass rational decision-making. One contributor noted the robotic voice delivered the threat, removing any opportunity for natural conversation or verification.

Call Characteristics and Patterns

Seven of the eight reports about 07 2143 6105 came through answered calls, with contributors able to hear the scam pitch directly. One contributor received a missed call from 0721436105 with no voicemail left, typical of mass-calling operations that rely on connecting with at least a percentage of dialled numbers.

The reports cluster heavily within a three-day period in late September 2024, with five reports submitted between 23-24 September. This concentration suggests either a targeted campaign by the scammer or heightened awareness during that timeframe. Reports continued into November 2025, indicating the number remains active for scam operations.

A notable pattern involves the apparent triggering of these calls: several contributors appear to have answered, triggering a recorded voice message. One report describes answering with "hello" and receiving a recorded voice saying "goodbye," suggesting an automated callback system or initial screening mechanism.
