One report for 0403 804 496 (0403804496): Contributor received unsolicited SMS, caller played dumb when contacted back. Optus mobile number.
Suspicious SMS Activity from 0403 804 496
A single contributor has reported receiving an unsolicited text message from 0403 804 496 (also written as 0403804496). What stands out about this report is the caller's evasive behaviour when contacted back - when the contributor called the number, the person who answered claimed not to understand or denied sending the message, despite the SMS arriving directly from that Optus mobile number.
This pattern of 'playing dumb' after an unsolicited text is a common obfuscation tactic. It suggests the sender may be testing whether the number is active, or attempting to avoid accountability if challenged. The contributor's willingness to call back shows they were suspicious enough to verify, which is sound instinct.
What the Contributor Reported About 0403804496
The contributor received a text from 0403 804 496 that prompted them to call the number directly. Instead of acknowledging the SMS or explaining its purpose, the person who answered feigned ignorance or claimed they had not sent it. This denial despite the message originating from that specific number raises questions about the sender's intent - whether accidental contact, deliberate evasion, or a probe to verify active phone numbers for later use.
What to Do If You Receive an SMS from 0403 804 496
If you receive an unsolicited text from 0403 804 496:
- Do not: Click any links in the message, reply to confirm your number is active, or call back expecting honest answers
- Do: Delete the message, block the number on your phone, and report it as spam via your mobile provider
- Do: Forward the SMS to 0429 999 888 (ACMA spam reporting) if the message appears to be phishing or contains suspicious links
The evasive behaviour reported here suggests the sender may try again or pass your number to other lists if you engage. Silence and blocking are your strongest responses.

WRITE A REVIEWFrequently Asked Questions
Should I call back a number that sent me an unsolicited SMS like 0403 804 496?
In this case, the contributor did call 0403804496 back out of caution, but encountered evasion. Calling back is risky because it confirms your number is active and monitored. If the sender denies sending a message that came from 0403 804 496, they are being deliberately evasive - this is a red flag. Block and report rather than engage further.
What does it mean when someone 'plays dumb' after sending an SMS from 0403 804 496?
Denying accountability for a message sent directly from 0403 804 496 suggests the sender is attempting to avoid consequences or wants to see if you'll engage without resistance. This tactic is often used by scammers testing contact lists or by bad-faith actors who don't want a paper trail. Do not assume it was accidental or innocent.
Is 0403 804 496 a scam number?
Based on the single report, the behaviour is suspicious - an unsolicited SMS followed by denial when questioned - but it has not been confirmed as a formal scam. The evasive response makes it worth blocking and avoiding contact. Optus mobile numbers can be spoofed or purchased by any user, so a legitimate-looking mobile number does not guarantee legitimacy.
Can I block 0403 804 496 on my phone?
Yes. On most Australian phones, you can block 0403804496 through your contacts or message settings. Your carrier (Optus, Telstra, Vodafone, etc.) also allows blocking through their app or customer service. Blocking prevents future calls and SMS from this number reaching you.
Should I report 0403 804 496 to the authorities?
If the SMS from 0403 804 496 contained a suspicious link, phishing attempt, or malware risk, report it to cyber.gov.au. For general spam or evasive SMS behaviour, report to 0429 999 888 (ACMA). Also report on Reverseau to flag the number for other Australians. Multiple reports strengthen the case for action.
Could this SMS from 0403804496 be a test to see if my number is active?
Yes, that is a plausible explanation. Scammers and spam operators sometimes send vague or blank SMS to test if numbers are active and monitored before launching a full campaign. The contributor's willingness to call back exposed the sender's evasiveness, which is actually useful intelligence. Do not engage again - block and report.
