WRITE A REVIEWFrequently Asked Questions
Why did 03 9003 9021 call me just after I activated my SIM?
New or recycled phone numbers are often on telemarketing and calling lists. When 0390039021 called immediately after your SIM activation, it suggests your number may have been on a database for unsolicited calling campaigns. Legitimate contacts would typically leave a voicemail if unable to reach you.
Should I call back the number 03 9003 9021?
No. If 0390039021 doesn't leave a voicemail, calling back serves no purpose and may confirm your number is active to the caller. If it's a legitimate contact, they'll try again and leave a message, or you can verify them independently.
Is 0390039021 a scam number?
Based on the single report received, 03 9003 9021 is flagged as suspicious due to a missed call with no voicemail on a new SIM. This pattern is common with unsolicited callers but doesn't conclusively identify it as a scam. More reports from contributors would help determine if 0390039021 is engaged in scam or spam activity.
What should I do if 03 9003 9021 calls again?
Block 0390039021 in your phone's settings to prevent future calls. If you receive multiple calls from 03 9003 9021 or similar numbers, submit a report on Reverseau so other Australians can check who called them. Persistent unsolicited calls should also be reported to the Do Not Call Register.
Can I report 0390039021 to the authorities?
If 03 9003 9021 engages in unsolicited marketing, report it to the Do Not Call Register at donotcall.gov.au. If you suspect scam activity, report to Scamwatch at scamwatch.gov.au or the ACMA at acma.gov.au. Contributing your report to Reverseau also helps other Australians identify suspicious numbers.
Why was there no voicemail from 03 9003 9021?
Callers running unsolicited campaigns often don't leave messages, especially when they're using auto-dialling systems. The absence of a message from 0390039021 is typical of mass calling operations that rely on reaching someone directly rather than leaving explanations. This is a red flag for unwanted contact.
