How to avoid the recent number change scam?

The most important thing is to look after yourself and don't believe what the other party says ~ If a friend says that he wants to change his number, you can call his original number to see if he has changed it, otherwise you can ask others if his friend has changed his number. Also, I will borrow money from you as soon as I change my number. Be careful. Nine times out of ten, you are a liar. In short, you should have a certain sense of fraud prevention. Also, you can install security software on your mobile phone, such as Teng Xun Mobile Manager, which can mark cheaters, and the usage base is relatively large, which can form a large number of marks.
