What if the game security center can't send text messages?

The mobile phone can't send short messages, so you can try to restart the mobile phone or change the mobile phone test.

Check whether the following situations exist: the SMS center number is set incorrectly, please re-enter the correct SMS center number, there is no signal or the battery of the mobile phone is low, and the system is busy during the peak period of holiday SMS sending. It is suggested to try again later or avoid the peak sending period, and the sending format is incorrect. If you send a short message to PHS users, you need to add the area code before the number.
