What if the overseas mobile phone number knows your name and sends you a message?

1. Don't talk to him or tell him after answering the phone. Don't call people you don't know, and don't send any messages. 2. Refuse to answer or hang up. This situation is mostly cheating money. Now is the era of big data, and individuals basically have no privacy. So it's best to keep a positive attitude, work hard and spend time and energy in worthwhile places.
