Nuisance Call Reports for 02 3815 5516
Two contributors have reported activity from 02 3815 5516 (also written as 0238155516), a local NSW number allocated to Symbio Networks. The reports indicate silent or non-responsive calling behaviour without voicemail messages, creating uncertainty about the caller's intent.
The pattern across reports of 0238155516 suggests potential callback request activity, where callers either hang up immediately or leave no message, hoping recipients will return the call. This behaviour is characteristic of callback scams or automated dialling systems fishing for active phone numbers.
What Callers from 02 3815 5516 Do
One contributor received a call from 02 3815 5516 with no message left and attempted to call back, but could not get through. Another Canberra-based recipient reported receiving three separate calls from 0238155516 over a period, again with no voicemail or explanation for the contact attempts.
The silence on these calls from 02 3815 5516, combined with the inability to reach the number when called back, suggests automated or click-through dialling rather than a legitimate service trying to reach the recipient.
Report Patterns and Timing
The two reports about 02 3815 5516 came from different contributors in February 2026. One report involved multiple call attempts (3 times) to the same Canberra number, while the other was a single answered call. Both contributors noted the caller left no message or explanation, making it impossible to determine legitimate purpose.
The callback request behaviour in one report is a red flag for potential scam activity, as legitimate organisations typically leave voicemail messages explaining the reason for contact.

WRITE A REVIEWFrequently Asked Questions
What happens if I call back 02 3815 5516?
Based on reports about 02 3815 5516, callers cannot be reached when you attempt to call back 0238155516. This is typical of callback scams, where the number either disconnects after the initial silent call or routes to an inactive line. Calling back may also incur premium charges depending on the number's classification, so it's best to avoid returning the call entirely.
Why would someone call 02 3815 5516 and leave no message?
Silent calls from 02 3815 5516 (0238155516) without voicemail messages are typically automated dialling systems designed to identify active phone numbers. Some callers use this tactic to confirm a number is active before attempting a callback scam. Others may be testing for engagement without revealing their identity or purpose.
Is 02 3815 5516 a legitimate business number?
02 3815 5516 is registered as a local service number with Symbio Networks in NSW, but legitimate businesses always leave voicemail messages or identify themselves. The fact that 0238155516 callers leave no message and cannot be reached when called back suggests the number is being used for nuisance or scam activity rather than genuine business purposes.
Should I block 02 3815 5516 after one call?
If 02 3815 5516 calls you once with no message, blocking is optional but reasonable. However, if 0238155516 calls repeatedly without leaving a message, blocking is recommended. Contributors who received multiple calls from this number found it more effective than trying to call back or waiting for a voicemail explanation.
What is a callback request scam?
A callback request scam occurs when a caller from a number like 02 3815 5516 hangs up or leaves no message, hoping you'll call back out of curiosity. The return call may be connected to a premium or international number (which 0238155516 does not appear to be) or used to verify your number is active for later targeting by scammers.
Who should I contact about repeated calls from 0238155516?
Contact your phone provider to report repeated calls from 02 3815 5516, and they can investigate or block the number. You can also report 0238155516 to ACMA at acma.gov.au for nuisance calling activity, and to Reverseau to help warn other Australians about this number's behaviour.
