Log in to WeChat with the verification code, but what if the mobile phone can't receive the verification code?

If you can't receive the verification code, please follow the following steps to check one by one.

1. Check the network status of the mobile phone.

Check whether the cell phone signal is normal and stable. If the signal received by the mobile phone is weak, take the mobile phone to a place with good signal and get the SMS verification code again. At the same time, avoid frequently obtaining SMS verification code.

2. Check the entered mobile phone number.

Check whether the entered mobile phone number is correct. If you enter it incorrectly, you will not receive the SMS verification code. At this time, correct your mobile phone number and get the SMS verification code again.

3. Avoid busy network periods.

Network busy period is usually the peak period of network use such as commuting, holidays, system server upgrade (early morning hours). If you can't get SMS verification code within this time, please try again later.

4. Check the phone bill and SMS function.

Call the operator's customer service phone to inquire about the phone bill balance information, and then select the manual service according to the voice prompt to check whether the SMS function on the operator side is normal.

If the phone is in arrears, pay it in time; If the SMS function on the operator's side is off, ask why it is off and seek recovery.

5. Check the SMS function settings.

Enter SMS settings and check whether the number of SMS center is set correctly (SMS center will not be able to send and receive SMS normally without correct number). When you are not sure about the number of the SMS center, you can call the operator's customer service phone and choose to obtain the service manually according to the voice prompt.

6. Check the SMS interception of the mobile phone security housekeeper.

Enter the security manager on the mobile phone to see if the security manager software intercepts and classifies the verification code. If there are such restrictions, you may wish to temporarily turn off the SMS interception and classification functions.

7. Kill mobile phone viruses.

Use the security housekeeper software on the mobile phone to thoroughly kill viruses, uninstall suspicious software, and prohibit software with the function of reading and writing short messages from using this function.

8. Restart the mobile phone, restore the factory settings and replace the mobile phone.

For older mobile phones, if there are too many messages stored (the mailbox is full), they will not be received. At this time you need to delete some useless messages.

Secondly, it may be a problem with the mobile phone system. Restart your phone to see if you can send and receive text messages normally, or put your mobile phone card on other phones.

If it is determined that it is a mobile phone problem, if conditions permit, back up the data on the mobile phone and restore the factory settings, or contact the after-sales department for handling.

Extended content: verification code

CAPTCHA is the abbreviation of "automatic public Turing test to distinguish between computer and human", and it is a public * * * automatic program used 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 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.
