Suspicious SMS Reports for 0403 836 829
Two contributors have reported receiving suspicious SMS messages from 0403 836 829 (also written as 0403836829). Both messages followed an identical pattern: a casual greeting using the recipient's name, followed by a question about how they've been. The personalized nature of these messages, combined with no apparent legitimate relationship, triggered concerns among contributors.
The number is registered to Optus Mobile and appears to be an active mobile service. The use of personal names in opening messages is a common social engineering tactic designed to create false familiarity and lower recipient defences before escalating to a scam request.
What Callers from 0403 836 829 Send
Both SMS reports from 0403836829 describe the same message pattern: "Good morning [name], how have you been?" or similar casual greetings that presume an existing relationship. Neither contributor reported context explaining who the sender claimed to be or what the intended follow-up might be.
This type of SMS is often a probe to establish whether a phone number is active and monitored. If you respond positively, a follow-up message typically escalates to a request for personal information, money transfer, or engagement with a malicious link.
Report Patterns and Timing
Both SMS messages arrived within a five-day window in early March, both during typical morning hours. The identical messaging suggests these may be part of a campaign rather than isolated incidents. Contributors received no additional follow-up SMS from 0403 836 829 after their initial message, though they chose to report the suspicious contact.

WRITE A REVIEWFrequently Asked Questions
Should I reply to a message from 0403 836 829 asking how I've been?
No. Do not reply to 0403836829 even if the message seems friendly or mentions your name. Replying confirms your number is active and monitored, which makes you a target for follow-up scam attempts. Block the number and report it to 0429 999 888 instead.
What does a personalized SMS like 'Good morning [name], how have you been?' mean?
This type of SMS from 0403836829 is a probe message. Scammers use your name (often obtained from data breaches) to create false familiarity and make you more likely to respond. Once you engage, they typically escalate to requests for money, personal information, or links to malicious websites.
Is 0403 836 829 a legitimate Optus number?
0403836829 is registered to Optus Mobile Pty Limited, but registration alone does not indicate legitimacy. Scammers often use legitimate mobile networks to send phishing SMS. Contributors have flagged this number as suspicious, so treat any contact from 0403 836 829 as untrusted.
What should I do if I've already replied to a message from 0403836829?
Block 0403 836 829 immediately and monitor your account for suspicious activity. Do not engage further even if follow-up messages arrive. If you shared personal information, consider changing your passwords and monitor your bank and credit accounts for unauthorised access.
How do I forward an SMS to 0429 999 888 to report 0403 836 829?
Most phones allow you to forward SMS. Open the message from 0403836829, select 'Forward', and send it to 0429 999 888. This reports the message to ACMA. You can also copy the message content and submit it on the Scamwatch website at scamwatch.gov.au.
Could this be from someone I actually know using a different number?
Unlikely if you don't recognise the number. If someone you know wanted to contact you, they would use their usual number or explain why they're calling from 0403 836 829. Scammers rely on this hesitation to bypass your caution. If you're uncertain, contact the person directly using a number you already have.
