WRITE A REVIEWFrequently Asked Questions
What does 'Unlock to me 123' mean in the SMS from 04 8139 8253?
The phrase is deliberately vague to trick you into clicking. It doesn't refer to anything real. Scammers use ambiguous language like this to bypass spam filters and create false urgency. The contributor who reported 0481398253 correctly identified it as a scam rather than engaging with the message.
Is 04 8139 8253 a real Optus customer or a scammer?
04 8139 8253 is registered as an Optus mobile number, but that doesn't mean the legitimate account holder is sending these messages. Scammers commonly compromise or spoof real mobile accounts to send phishing SMS. The Optus account may have been hacked or the number spoofed entirely.
What happens if I click the link in the SMS from 0481398253?
Clicking the link from 0481398253 could lead to credential theft, malware infection, or confirmation of your number as active (resulting in more scams). The contributor who received this SMS wisely avoided clicking and reported it as a scam.
Should I reply to tell 04 8139 8253 to stop messaging me?
No. Do not reply to 04 8139 8253 or any phishing SMS. Replying confirms your number is active and monitored, likely triggering more scam messages. Simply delete and block the number in your phone settings.
Can I report 0481398253 to Optus directly?
Yes. Contact Optus customer service at 133 Optus and report the phishing SMS from 04 8139 8253 as fraudulent. Optus can investigate whether the account was compromised and take action. Also report the number on scamwatch.gov.au and acma.gov.au.
Why would a scammer use an Optus mobile number instead of a landline?
Mobile numbers like 04 8139 8253 are harder to trace and often bypass spam filters more easily than obvious VoIP numbers. Scammers prefer mobile accounts because they appear more legitimate and are less likely to be flagged by automated systems monitoring 1300/1800 numbers.
