SMS impersonates an acquaintance and asks for the number.

Suddenly received a text message from a friend, but the phone number is a strange number, which may be one of the following situations:

1. Fraudulent information: Some scammers will use their friends' names to obtain personal information and then cheat. They usually send text messages or make phone calls in the name of friends to defraud money or personal information.

2. Mass SMS: Sometimes, friends may send messages through the mass SMS function, but for some reason, the number may not be correctly included in your contact list.

3. New friend: If this friend met only recently, they may add your number to their contact list in some way, so you received their message.

4. Wrong sending: Sometimes friends may send short messages by mistake for some reasons, such as losing their mobile phones, borrowing their mobile phones, and so on.

5. Computer virus: Some hackers may spread viruses or malware by sending short messages from friends. If you doubt the truth of the news, don't click on the link or attachment and contact the police immediately.

The best way is to reply to text messages and ask friends about the real situation. If a friend says he didn't send a text message, you should be vigilant, don't trust the content of the text message easily, and pay attention to protecting personal information and property safety.
