A liar who wants to cheat will not be found out simply because of a mobile phone number, so everyone needs to strengthen the awareness of fraud prevention. [Development data] How to deal with telephone fraud 1. Check whether it is a strange number. This is very important. Because when some fraud calls, they will approach you, claiming to be your friends or relatives. You were very polite. At this time, you should first be very sensitive to see if it is a strange number? This number is not in your phone book. Don't talk to others blindly. 2. Be able to resist temptation. When you receive some calls, you claim to be from a bank or a big company. At the same time, how many benefits or conveniences will be provided for you? At this time, you should never be interested in what they say, or cannot help talking, so that the other party will wait for an opportunity to cheat or call again. 3. Control your emotions. Some fraud calls will tell your relatives, classmates and friends that something has happened. At this time, never get excited when others say you will remit money. Learn to be calm, and don't look worried. Ask the other person's situation lightly, and then ask a few questions. After hanging up the phone, call your friends and relatives to confirm the specific situation. This is usually a hoax. 4. Don't pay attention to the other party. Don't say anything if you can. When we receive a strange phone call, the other party may approach you at the beginning. At this time, we must be alert. We'd better keep silent or ignore the questions raised by the other party. Once what the other party says doesn't interest you at all, his fraud is also difficult to achieve. So you should control your mouth, learn to choose silence and resist temptation. 5. Timely record and retain evidence. Many mobile phones now have the function of recording during a call. Once you find something strange in what the other person says or the language, you should try to press the recording key to record the other person's voice. As a strong evidence, it may be useful! This is the relevant law about your problem.
