Try to upgrade the mobile phone system.

Check whether the SIM card is in arrears, which may affect mobile phone communication.

Confirm whether the number of SMS center is set correctly. Please consult the operator for details.

Check whether there are sensitive words in the short message content, or repeatedly send short messages to the same number, resulting in being blocked by the operator. Please consult your local operator for details.

Check whether there is a blacklist in the "mobile phone housekeeper", which causes the message to be intercepted and cannot be received. If so, please delete the number from the blacklist and try again.

Check whether there is a third-party application intercepting SMS. Some security management applications will intelligently filter the received short messages, so it is recommended to uninstall this application.

When the cell phone is in a place where there is no signal or the signal is weak, the information may not be sent successfully. Please try again where the signal is strong.

The network system is busy, especially during the peak period of holiday information transmission, and the information transmission may be unsuccessful. Please avoid the rush hour and try again.
