Why can't WeChat receive SMS verification code?

There are several reasons why the WeChat verification code cannot be received:

There is no charge for mobile phones. If you don't receive the message, you won't receive the SMS verification code. In this case, the mobile phone can accept SMS after charging, or change the mobile phone number.

The cell phone signal is not good, so it can't be sent to the cell phone. Let's find a signal and try again.

The validity period of WeChat SMS is generally 10 minutes, so in general, you only need to receive the message within 10 minutes. If you can't accept it, you can see if the prompt on WeChat is an error in entering the mobile phone number. Or contact WeChat customer service.

Verification code is the abbreviation of "full-automatic public beta Totell Computer and Humansapart", and it is a public beta program that automatically distinguishes whether a user is a computer or a person.

It can prevent malicious password cracking, ticket brushing and forum flooding, and effectively prevent a hacker from constantly trying to log in to a specific registered user and using a specific program to violently crack. In fact, using verification code is a popular way for many websites now, and we have realized this function in a relatively simple way.

This question can be generated and judged by computers, but only humans can answer it. Because the computer can't answer CAPTCHA's question, the user who answers the question can be considered as human.
