The number +646424388555 appears to be associated with persistent, silent calls targeting recipients in Australia. The caller does not engage in any communication when the call is answered, which is a hallmark of robocalling or telemarketing scams. These types of calls are often automated, designed to either test the number's validity for future spam campaigns or to prompt callbacks, which can lead to premium charges. The frequency of the calls over the last couple of months suggests a systematic approach, likely tied to a larger network of similar operations. While the caller's identity remains unknown, the behavior aligns with patterns observed in mass-calling schemes. It is advisable to block the number and report it to relevant authorities to mitigate further disruptions.
Mystery caller from Australia keeps ringing, no reply when we pick up, any tips?, yeah.
