What is the verification code of the questionnaire for parents of students in compulsory education? What if I can't see the verification code?

Generally speaking, the verification code of the questionnaire for parents of compulsory education students can be obtained by filling in their current mobile phone number and then completing the verification code. Then you enter your mobile phone number, and the system will automatically send you a verification code. Just enter it when you receive it. You can check and confirm whether the phone number is entered incorrectly. 2. Whether the mobile phone is equipped with interception software or turn on anti-harassment function. Now the Android mobile phone system comes with it. If Apple's mobile phone is installed with third-party security software, it may be blocked. You can go to the interception center to see if there is any relevant information. 3. Whether the current network is stable may delay. It is suggested to choose a stable network or machine to run, so as to reduce the influence of network delay. 4. There are some backstage problems of websites or software, and the information transmission is slow.

Other reasons: 1. Poor network signal is a common reason. We need to observe whether the cell phone signal is full. The way to deal with this problem is also very simple. Just go out and see if it has recovered, or shut down and restart, take out the SIM card and try again to see if it has improved. 2. Gateway congestion If the SMS gateway is congested, there will be a delay in sending SMS, which is unacceptable. In that case, you need not worry. You need to try again after a while. 3. Mobile phone security software interception Sometimes we will blacklist some mobile phone numbers that we think are harassing or unused, but the next time we forget this operation, the mobile phone will also be unable to receive the SMS verification code. If this is the case, we just need to find and open the SMS interception software and change this number to the white list. This number was blocked by the operator. If we had sent an unsubscribe instruction to the relevant operator before and blocked a number, we naturally could not receive the short message sent by the mobile phone. This situation is relatively rare. If there is, just call customer service to cancel.
