I received a call claiming to be mobile customer service, saying that 5 yuan can enjoy 500 megabytes of traffic.

The verification code is to prove the identity of the owner, which is equivalent to an ID card. This kind of leakage is very harmful.

The mobile phone number displayed by the caller may not be true sometimes, because there is a software to change the number.

If the message comes from customer service, it is usually a short number. 1 1 digit mobile phone numbers are private.

When you meet a short phone call or text message, you need to confirm it by other means. For example, take the initiative to call the customer service hotline to ask.
