WRITE A REVIEWFrequently Asked Questions
Why would a scammer claim I won a competition I never entered?
Prize scams work on the premise that many people hope they've entered competitions they've forgotten about. The SMS from 0402 435 503 banking on this psychology, then switching to a payment demand once the recipient is emotionally invested in the 'win'. It's a low-effort, high-volume approach.
Is 0402 435 503 really from Optus?
The number 0402435503 is registered to Optus Mobile as a mobile service, but that doesn't mean Optus sent the SMS. Scammers can send messages that appear to come from legitimate mobile numbers, or they purchase bulk SMS services to distribute their scams. The actual sender is the fraudster, not Optus.
What do the spelling mistakes in the SMS from 0402 435 503 mean?
The misspellings reported in the message from 0402435503 indicate a mass-produced scam template. Legitimate companies proofread competition notifications carefully. Spelling errors are a deliberate or lazy aspect of bulk scam campaigns sent to thousands of people at once.
If I already replied to the SMS from 0402 435 503, what should I do?
If you've replied to or engaged with 0402435503, block the number immediately and monitor your accounts for suspicious activity. Do not make any payment. If you've already paid, report it to your bank and Scamwatch at scamwatch.gov.au immediately, and file a police report online.

Contact your bank or mobile provider immediately to report the fraudulent charge from 0402435503. They may be able to reverse the transaction if reported quickly. Also report to Scamwatch (scamwatch.gov.au) and the ACMA (acma.gov.au). Police reports can assist your bank's investigation.
