Why can’t I receive the SMS verification code?

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

The mobile phone has no charge. If the message cannot be received, the SMS verification code will not be received. In this case, the mobile phone needs to be recharged. You can receive text messages after paying the fee, or just change your mobile phone number.

The mobile phone signal is not good and cannot be sent to the mobile phone. Find a place with better signal and try again.

The validity period of WeChat text messages is generally 10 minutes, so usually you only need to receive the message within 10 minutes. If you cannot accept it, you can check the prompt on WeChat to see if the mobile phone number was entered incorrectly. Or contact WeChat customer service.

The verification code is "CompletelyAutomatedPub licTuringtesttotellComputersandHumansApart" (fully automated Turing test to distinguish computers and humans), is a method to distinguish between users Is it a computer or a human company's fully automatic program.

It can prevent: malicious password cracking, ticket fraud, forum flooding, and effectively prevent a hacker from using a specific program to brute force a specific registered user to continuously log in. In fact, many people use verification codes now. We implemented this function in a relatively simple way using the popular website method.

This question can be generated and judged by a computer, but only a human can answer it. Since computers cannot answer CAPTCHA questions, the user who answers the questions can be considered a human.
