Personal Information Request Reports for 04 9359 4753

One contributor has reported receiving a suspicious SMS from 04 9359 4753 (also written as 0493594753) requesting a temporary SIM number. The notable aspect of this report is that the sender did not identify themselves and appeared to be using a social engineering tactic to prompt a response from the recipient.

The contributor flagged the request as dodgy, recognising that legitimate organisations typically identify themselves before requesting sensitive information. This type of approach-asking for a temporary SIM number without establishing identity-is a recognised method used by bad actors attempting to gain access to accounts or intercept communications.

What the SMS from 04 9359 4753 Says

The message from 0493594753 asked the recipient for a temporary SIM number but provided no context, organisation name, or reason for the request. The contributor noted the sender didn't have their name, which further suggests the message was either sent indiscriminately or obtained through data aggregation.

Requests for temporary SIM numbers are typically used in account takeover attempts, where attackers aim to receive verification codes intended for the original account holder. By obtaining a temporary SIM, bad actors can intercept two-factor authentication messages and gain unauthorised access to email, banking, or other sensitive accounts.

Report Details and Context

The report came through SMS on 21 October 2025. The number 04 9359 4753 is allocated to Telstra Limited as a mobile service. The single report indicates this was an unsolicited contact attempting to manipulate the recipient into providing sensitive information without proper verification or disclosure of intent.

Understanding Personal Information Requests

Scammers often request temporary SIM numbers, one-time passwords, or verification codes under false pretences. These requests typically come from unknown numbers or unidentified senders. Legitimate organisations already have your phone number on file and will never ask you to provide temporary SIM details via unsolicited SMS. If you receive similar requests from 04 9359 4753 or any unfamiliar number, treat them as suspicious and do not engage.
