Hello, whether a phone call is fraudulent is usually judged according to the content of the call, but it is still impossible to judge whether it is fraudulent according to the information you provided. In addition, you mentioned that if interception is set, there will be no property loss, which is abnormal. You can set the interception, or you can just hang up and ignore it.
