Today, someone called to help me upgrade my broadband and asked me to receive the 6-digit mobile phone verification code sent by 10086. Does this affect him?

Liars are smart now. The pseudo base station is hidden in his backpack, pretending to be mobile, Unicom or telecom to send you short messages. In the name of broadband upgrade, he asks you to send him a mobile phone verification code [pseudo base station]. After he obtains your mobile phone verification code, he can copy your mobile phone number and invalidate your mobile phone card. The WeChat, Alipay and bank card bound to your mobile phone number will be very dangerous, and the money will be easily stolen. It's even worse if you use your phone number to cheat friends and relatives. I received many short messages from 10086, including free installation of100M broadband, free delivery of100RMB phone bill, free delivery of traffic and free delivery of mobile phones. I just ignored them. Occasionally go to the mobile business hall to check, the waiters shake their heads, and there are almost no free dinners in the world! Don't always think of beautiful things! When you encounter something good, go to the business hall to verify it, so as not to be taken in by a liar!
