How did Xiaomi's mobile phone card get the text message?

Android phones always receive 10086 error messages, mainly because customers use the "automatic traffic calibration" function that comes with the mobile phone system or in the third-party security management software. When this function is turned on, the mobile phone will automatically send a short message to 10086 to check the traffic according to the calibration frequency set by the customer (such as daily/every three days/weekly). If the setting of "Automatic Traffic Calibration" is wrong, the calibration SMS instruction sent by the mobile phone does not match the inquiry instruction of the SMS business hall in the province where the customer is located, which will cause 10086 to reply the wrong instruction SMS to the customer.

If the customer does not want to receive such information, it can be handled as follows: 1. The source of the verification function is the "automatic flow calibration" function in the mobile phone system or the third-party security management software; 2. Verify whether the sending instruction is correct, enter the "automatic flow calibration" function and check whether the setting content is correct; 3. If the customer does not need flow calibration, he/she needs to turn off the "automatic flow calibration" function in the program.
