Why does Huawei Maimang 4 receive a short message from 10086 every day? What's the problem?

Dear, I suggest you follow the following methods:

The mobile phone traffic management function supports "automatic calibration at regular intervals", and sends a free short message to the operator regularly every day to check the traffic. The setting method is: All Settings-Traffic Management-Package Settings-Automatic Periodic Calibration. This function can be turned on and off.

Some third-party applications, such as Baidu Mobile Guardian, automatically send text messages to 10086 every day to get the current traffic usage, which is used to show your current traffic usage; Solution: Enter SMS sending in Mobile Manager-Permission Management-Permission, check the list of SMS sending applications, and "block" the SMS permission of third-party applications.
