02 8271 4905 (0282714905): Community reports of repeated robocalls threatening SIM cancellation in 3 days with language selection prompts. Calls originate from 028271 prefix with varying final digits.

SIM Card Threat Robocalls from 02 8271 4905

Two contributors have reported receiving repeated scam calls from 02 8271 4905 (also written as 0282714905) using a robocall system with a consistent threatening message. The callers claim they will cancel the recipient's SIM card within 3 days, then offer a language selection prompt requesting either 1 for Chinese or 2 for English. The calls originate from the 028271 prefix allocated to Optus Networks in NSW, though the final four digits vary between calls.

The pattern suggests an automated robocall campaign targeting Australian mobile users. Both contributors noted that when they attempted to call back the number, they reached an "unavailable" message rather than connecting to a person or organisation, a common indicator of spoofed numbers used in scam operations.

What Callers from 02 8271 4905 Claim

The robocall from 0282714905 delivers a recorded threat stating the recipient's SIM card will be cancelled within 3 days. After this threat, the automated system prompts the caller to select their preferred language by pressing 1 for Chinese or 2 for English. Contributors report the message is delivered in a robotic voice with no attempt to verify the recipient's identity or provide legitimate reason for the alleged cancellation.

One contributor noted the calls come from varying numbers within the 028271 range, suggesting the scammers are rotating through a block of numbers to avoid rapid blocking. This tactic makes it harder for users and telecommunications providers to identify and stop the source quickly.

Call Patterns and Timing

Contributors report receiving "keep getting calls" from the 02 8271 4905 range, indicating repeated contact rather than a single attempt. The use of different final four digits within the 028271 prefix suggests the scammers have access to multiple numbers from this Optus-allocated range in NSW. This rotating approach is a common evasion tactic used by international scam operations to circumvent blocking measures.

The callback mechanism also reveals the scam structure: when recipients attempt to return a call to 0282714905, they encounter a "message not available" response rather than reaching any legitimate service. This confirms the numbers are spoofed or improperly allocated, with no actual destination on the other end.
