Suspicious SMS from 0402 852 920

A contributor has reported receiving an SMS from 0402 852 920 (also written as 0402852920) containing only the word 'wow'. This type of message is often used in number verification scams or to test whether a number is active and monitored by a real person.

The SMS was sent to a mobile number, and the brevity of the message combined with its unusual nature suggests this may be part of a larger scam operation. Callers and SMS senders often use vague messages like this to probe for active phone numbers before launching more sophisticated fraud attempts.

What This SMS Message Indicates

Single-word SMS messages from unknown numbers like 0402 852 920 typically serve one of these purposes:

• Number verification - scammers testing if the number is actively used
• Callback bait - attempting to trigger a response that reveals you answer unknown contacts
• Phishing probe - checking if you'll engage with the sender
• Part of a data harvesting operation - confirming valid phone numbers for sale

The fact that 0402852920 is an Optus mobile number makes it easier for scammers to blend in with legitimate communications, as it appears to be a standard Australian mobile rather than a business or spam line.
