Why did China Mobile shut down my SMS function? ?

Automatic monitoring of China mobile short message platform. If users send more than 50 messages at a time, the system will automatically identify them as bad users, which means that the system will automatically turn off the SMS function. After you stop sending messages for 24 hours, the SMS platform will automatically turn on the SMS function for you. This is required by the Ministry of Industry and Information Technology to control spam messages. Not what China Mobile wants to do. China Mobile certainly wants users to send more messages!
