I called 10086 because the newly bought mobile phone card always failed to send short messages, and he told me to restart and shut down.

Hello, in this case, I suggest you put your mobile phone card in another mobile phone that can send and receive short messages normally. If everything is normal, it may be caused by the phone settings. I suggest you contact the mobile phone manufacturer for advice on how to adjust the settings. If you can't send and receive SMS normally after putting it into other mobile phones, it may be that there is something wrong with the card itself. It is recommended that you bring your valid ID card and mobile phone card, and it is best to bring your mobile phone to the main business hall of Beijing Mobile to check the card. Please refer to.
