Why does the mobile phone automatically send 102 to the operator?

Reason 1: The mobile phone traffic management function supports "regular automatic calibration" and will send free text messages to the operator regularly every day to check the traffic.

Solution: All settings-traffic management-package settings-regular automatic calibration, you can turn this function on and off.

Reason 2: Some third-party applications, such as Baidu Mobile Guard, will automatically send a text message to 10086 every day to obtain the current traffic usage, which is used to display the current traffic usage of the mobile phone.

Reason three: If a third-party application that is not preset on the phone sends text messages in the background, it will be recorded by the phone and can be seen in the text message interface. This display method is to remind mobile phone users that suspicious third-party applications are installed.

Solution: Go to Mobile Phone Manager - Permission Management - Send SMS in Permissions, check the list of applications that send text messages, and "disable" the text messaging permissions of third-party applications.
