If your mobile phone can't send SMS, you can try to restart or replace your mobile phone for testing and check whether the following conditions exist:

1. SMS center number is set incorrectly, please re-enter the correct SMS center number;

2. There is no signal or the battery of the mobile phone is low;

3. Because the system is busy during the peak period of holiday SMS sending, it is suggested that you try again later or avoid the peak period of sending;

5. The short message sending time exceeds 24 hours;

6. The mobile phone shields the short message sending function;

7. Blacklisted by SMS;

8. Insufficient quantity balance;
