What should I do if the 24-hour SMS verification code of this business exceeds the system limit when I make an appointment for subject 2?

Just make an appointment the next day. This situation shows that you have made too many appointments, which exceeds the system limit and you cannot make an appointment. I hope I can help you!

The function of verification code is as follows:

1 to prevent malicious programs from trying to log in by brute force.

3, to prevent a large number of malicious programs from registering, occupying the resources of the website server, and publishing spam to cause the website to crash.

4. Comment posting module: prevent spam posts and advertisements from being swiped, so that forums, blogs and other websites cannot run.

5. Others: some places such as voting activities, snapping up goods, and grabbing tickets will also use verification codes to prevent brushing tickets.
