What should I do if I can't receive the verification code when my mobile phone is down?

You can collect the verification code if your mobile phone is in arrears.

If the phone stops in one direction and can answer the phone, you can receive the verification code. If the phone has been stopped in both directions, you will not receive the verification code. That is to say, if the mobile phone is in arrears for more than three days, there will be a buffer period of one to three days, which means that you can't take the initiative to call others during these one to three days, but you can answer the phone or receive information.

However, if the mobile phone is in arrears for more than three days, then generally speaking, the mobile phone cannot receive the verification code. Even if someone calls, they can't answer normally. Therefore, if the mobile phone needs to receive the verification code, and the arrears have exceeded three days, the only way is to make up the arrears.

Importance of verification code

Verification code is the abbreviation of Turing test to automatically distinguish between computer and human, and it is a public * * * automatic program to distinguish whether the user is a computer or a human. It can prevent malicious password cracking, ticket brushing and forum flooding, and effectively prevent hackers from constantly trying to log in to specific registered users by using specific program brute force cracking methods.

In fact, using verification code is a popular way for many websites now, and this function is also realized in a relatively simple way. Because of its randomness and simplicity, verification code technology can hinder malicious behavior from accessing the network to a certain extent, and it has been widely used in the Internet field. Picture verification code is to obtain the required sample picture by crawler, separate the characters and letters in the picture, and identify the verification code by neural network algorithm.
