Send a text message saying it's an old classmate scam

Old-fashioned telephone fraud method: criminals dial your phone first, not to say who it is. Victims are often influenced by emotions, and Lenovo guesses the identity of the other party. Criminals agree with the trend and say that they will visit the victims in the near future to pave the way for the next fraud. The next day, I made up a lie that I had an accident on my way to visit, or that I was caught whoring or taking drugs to borrow money from the victim, so that the victim could remit the money to the designated account.

In this case, the first thing to ask is who. Don't be embarrassed. I hope you will be vigilant.
