Suspicious Mandarin-Speaking Calls from 04 8908 6188

Two contributors have reported suspicious calls from 04 8908 6188 (also written as 0489086188), an Optus mobile number. Both callers were speaking Mandarin, leaving contributors confused and unable to understand the purpose of the calls. The language barrier combined with the unsolicited nature of the contact raised red flags for those who picked up.

One contributor described the caller as "jabbering in Mandarin" with an overall feeling that something "didn't feel right". Another report noted the caller was speaking Chinese, with the contributor unable to comprehend any part of the conversation. The consistent language pattern across both reports suggests this may be a coordinated calling campaign rather than individual wrong numbers.

What Callers from 04 8908 6188 Say

Reports indicate callers from 0489086188 do not attempt to communicate in English despite reaching Australian phone numbers. Both contributors who answered were met with sustained Mandarin-language speech, with no attempt at code-switching or explanation of the call's purpose. The callers continued speaking despite recipients clearly not understanding them, suggesting the calls may be automated or part of a mass dialling operation.

Neither contributor was able to establish what the caller wanted or claimed to be calling about. This inability to communicate intentionally or the robocall nature of the contact makes it difficult to classify whether 04 8908 6188 is attempting a scam, conducting market research, or simply reaching wrong numbers through indiscriminate dialling.
