Robocall and Urgency Scam Reports for 03 8747 3155
Two contributors have reported suspicious activity from 03 8747 3155 (also written as 0387473155), a Victorian local service number allocated to Symbio Networks. The reports describe robocall behaviour combined with high-pressure messaging designed to prompt immediate action. One contributor received a voicemail claiming repeated call attempts with a threat of SIM suspension, while another experienced a missed call with no message left.
The voicemail from 0387473155 specifically referenced multiple failed contact attempts and warned that the SIM would be "marked" if contact wasn't reestablished. The message offered language options (English or Chinese), a common robocall feature that allows mass distribution across different speaker populations.
What Callers from 03 8747 3155 Say
The voicemail from 03 8747 3155 uses a scripted, automated message structure. A contributor reported the exact phrasing: "Called several times, I have message notification, if they can't get through again SIM will be marked." The message then offers "Press 1 for English, 2 for Chinese," indicating a robocall system routing calls to different language handlers or recorded responses.
This approach is typical of scams targeting mobile phone users. The urgency element (repeated calls, SIM suspension threat) is designed to trigger panic and encourage the recipient to press a button or call back, confirming the number is active and owned by a real person. The multilingual routing suggests the scam may be operating at scale across multiple demographics.
Report Patterns and Call Behaviour
Of the two reports about 0387473155, one arrived as a voicemail and one as a missed call. The voicemail indicates the caller has already attempted contact multiple times before leaving the recorded message, suggesting this number operates with systematic call sequences. The robocall nature means this is not a live operator but an automated dialling and messaging system.
The allocation data shows 03 8747 3155 is registered as a local service in Victoria under Symbio Networks. However, the robocall tactics and threat messaging suggest the number may have been compromised, spoofed, or is being used fraudulently by scammers operating the automated system.

Why did 03 8747 3155 say my SIM would be marked?
The voicemail from 03 8747 3155 (0387473155) uses a fake threat to create urgency and trick you into pressing a button or calling back.
