How to determine whether "mobile customer service personnel" ask for verification code is fraud?

The person in charge of the mobile business hall reminded not to tell anyone about the SMS verification code. Telecom operators such as China Mobile will only issue SMS verification codes to users, and will never require e-ticket passwords and SMS verification codes. It is fraud to ask the user to do the so-called "reply verification code" when encountering a strange number.

This is not a lie, because now you need a verification code to do business and change packages.

When receiving the dynamic verification code, please carefully check whether the business type, transaction merchant and amount in the SMS are correct.
