What should I do if my mobile phone is in arrears and I can't receive the SMS verification code?

The mobile phone is in arrears. If you can't receive the verification code, you have to pay first.

You can't receive any text messages after the phone is stopped. After the phone is stopped, you can't receive SMS normally. Only by paying off the arrears and reopening can you receive the verification code. You can't use your mobile phone to recharge the payment after the phone is stopped. You can only ask others to recharge your payment. After recharging, you can receive the verification code normally with your mobile phone.

The mobile phone can receive any short message and any phone call within 24 hours after it is stopped due to arrears, but it cannot send short messages and dial out calls (except the operator's customer service number and 1 1 alarm phone). After 24 hours of downtime, you can't send and receive SMS at all (you can call the operator's customer service phone number and 1 1 alarm phone number), and the number will be automatically cancelled after 3 months of downtime.

The important role 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.
