WRITE A REVIEWFrequently Asked Questions
Why do multiple numbers in the 9970 81xx range keep calling me?
Spam campaigns often use sequential or spoofed numbers to avoid blocking. When you block 03 9970 8140, the caller may rotate to a similar number like 03 9970 8141 or 03 9970 8142. This tactic makes it harder for people to permanently block the source. If the pattern continues, block all similar numbers and register with the Do Not Call Register at donotcall.gov.au.
Should I answer calls from 03 9970 8140 to find out who's calling?
No. Answering calls from 03 9970 8140 or similar numbers in the 9970 81xx range confirms your number is active and monitored, which often increases the frequency of spam calls. Let the call go to voicemail. If no message is left, as reported by the contributor for 0399708140, it's almost certainly spam. Block it immediately.
What does it mean when a number calls but leaves no voicemail?
When 03 9970 8140 calls but doesn't leave a message, the caller's goal is typically just to generate missed calls, test whether your number is active, or hope you'll return the call out of curiosity. Legitimate callers almost always leave a voicemail explaining why they called. The pattern reported for 0399708140 strongly suggests automated spam dialling.
Is 03 9970 8140 a scam or just spam?
Based on the single report, 0399708140 appears to be spam rather than a scam. The contributor reports missed calls with no voicemail message, not a scam attempt. However, the persistent nature and use of multiple similar numbers (9970 81xx range) in the 03 area code indicates organised spam activity. It's not attempting to steal money or information, but it is unwanted harassment.
How do I block an entire range of numbers like 9970 81xx?
Most phones do not allow blocking a number range natively, but you can manually block multiple similar numbers to 03 9970 8140 as they call. Alternatively, use a third-party call-blocking app such as Truecaller or similar services that can recognise patterns and block ranges. Your phone's native blocking (Settings > Phone > Call Blocking & Identification) will block individual numbers like 0399708140 one at a time.
Should I report 03 9970 8140 to the Do Not Call Register?
Yes. Even though 0399708140 appears to be spam rather than legitimate telemarketing, registering your own number with the Do Not Call Register at donotcall.gov.au can reduce some unsolicited calls. If calls from 03 9970 8140 persist after registration, you can report the number directly to ACMA at acma.gov.au for breaching Do Not Call rules.
