Scam and Silent Call Reports for 07 3171 3830
Six contributors have reported activity from 07 3171 3830 (also written as 0731713830), a Queensland local number. The reports reveal a mixed pattern of behaviour: investment scams, silent calls, and callback requests. One contributor received an abusive callback after declining an investment pitch, while others encountered silent calls or robocall recordings claiming to be from Quantum AI and Energy Plus.
The allocation data shows this number is serviced by Symbio Networks in Queensland, though the varied caller identities and tactics suggest either spoofed use or multiple bad actors using the same line.
What Callers from 07 3171 3830 Have Done
Contributors who answered calls from 0731713830 reported several distinct approaches. One received a call from someone with an American accent pitching investment opportunities. When that contributor responded in Czech, the caller became abusive on a second call, suggesting hostile behaviour when faced with a language barrier or rejection.
Another contributor called back after a missed call and heard a recorded message claiming to be from "Energy Plus," suggesting the initial call was either a scam spoofing Energy Plus's identity or a callback scam trying to prompt return calls.
A third report described a late evening call (after 9 PM Friday) from someone claiming to represent "Quantum AI," stating the contributor's account "looks good"-a common opening line in investment or financial scams designed to build false trust before requesting money or personal details.
Two separate reports describe silent calls where either no one responded when the contributor answered, or the line hung up immediately. These silent calls occurred across different dates, suggesting either automated network probing or intentional call-list validation tactics.
Call Patterns and Timing
The six reports span from June 2023 to March 2026, indicating sustained activity from this number over an extended period. One contributor reported multiple calls throughout day and night with no response when answered, consistent with silent call harassment or automated dialling patterns.
A report from February 2024 noted a call arriving after 9 PM on a Friday, outside normal business hours-a timing often used by scammers to catch people off-guard or less likely to verify claims. Another missed call in February 2024 was interpreted by the contributor as a "number checking" attempt, where callers probe whether a phone is active before targeting it with scam calls.

WRITE A REVIEWFrequently Asked Questions
Why did the caller from 07 3171 3830 become abusive when I spoke Czech?
One contributor reported that a caller with an American accent initially called about investment opportunities, then called back and became aggressive when the contributor responded in Czech. This behaviour suggests the scammer was unprepared for a non-English response and may have panicked or become frustrated, indicating a script-based operation with limited flexibility. The abusive callback also demonstrates the caller was tracking and following up on the initial contact.
What does the Energy Plus recording from 0731713830 mean?
A contributor heard a recorded message claiming to be from Energy Plus after calling back a missed call from 07 3171 3830. This is typical of a callback scam where the number spoofs or mimics a legitimate company's identity to appear trustworthy. Do not return calls to numbers you don't recognise, as you may be enabling the scammer to confirm your number is active and answered by a real person.
Is Quantum AI a real investment company calling from 07 3171 3830?
No. A contributor received a late-night call from someone claiming to represent Quantum AI, saying the contributor's account "looks good." This is a common investment scam tactic. Legitimate investment firms do not cold-call people claiming accounts are "good" without prior relationship. If you're unsure, hang up and contact the company directly using contact details from their official website, never numbers provided by callers.
Why am I receiving silent calls from 0731713830 multiple times a day and night?
Two contributors reported silent calls or calls with immediate hang-ups from 07 3171 3830, with one noting calls throughout day and night. Silent calls are often used to validate whether a phone number is active and answered by a real person. This information is then sold or used to target the number with more scam attempts. Block the number immediately and report it to ACMA at acma.gov.au.
Should I call back 07 3171 3830 to find out who's calling?
No. Several contributors' experiences with 0731713830 show that returning calls can connect you to either robocall recordings (Energy Plus), abusive callers (investment scam), or confirm to scammers that your number is active and monitored. If a legitimate organisation needs to reach you, they will leave a voicemail or contact you through official channels. Avoid returning calls to unknown numbers.
What should I do if 07 3171 3830 keeps calling after I block it?
If calls from 0731713830 persist after blocking, the number may be spoofed (faked), meaning different scammers are using different numbers or masking their real number. Document the dates and times of calls, take screenshots, and report to ACMA at acma.gov.au or call 1300 850 152. You can also file a report on Reverseau to help other Australians and build evidence of the pattern.
