Why does the mobile phone always send 102 to 10086 automatically?

The first reason: the mobile phone traffic management function supports "regular automatic calibration", and sends free short messages to operators regularly every day to check the traffic.

Solution: all settings-traffic management-package settings-automatic periodic calibration. This function can be turned on and off.

Reason 2: Some third-party applications, such as Baidu Mobile Guardian, automatically send short messages to 10086 every day to get the current traffic usage, which is used to display the current traffic usage of mobile phones.

Reason 3: A third-party application that is not preset by the original mobile phone factory sends a short message in the background, which will be recorded by the mobile phone and can be seen in the short message interface. This display mode is to remind mobile phone users that suspicious third-party applications are installed.

Solution: Go to Send SMS in Mobile Manager-Rights Management-Rights, check the list of applications that send SMS, and "block" the SMS rights of third-party applications.
