Why can't I get a short message when I pop up the window to correct the error on Beijing 12345?

The verification code cannot be received for the following reasons:

1. The mobile phone has no mobile phone card installed, the mobile phone number is in arrears, there is no signal, etc., and the mobile phone card is damaged.

2. Whether security software is installed in the mobile phone, the blacklist setting of security software will intercept such short messages. We can check whether the short messages with 12345 verification code are intercepted.

3. If we submit an application for SMS verification code through the website, and the security level of our browser is relatively high or "third party 12345 and website data" is blocked, the request for SMS verification code may not be delivered to the other party's background, so we need to reset the security level of the browser or turn off the setting of "Block third party 12345" in the browser.
