This is due to the fact that some software has obtained the permission to turn on mobile data traffic, if you only access the Internet through wifi, you can turn off the permission of the software to obtain mobile data, and the method of closing is as follows:

Open 360 Security Guard, click Traffic Monitoring to turn on, and then click Network Management to turn on.

The options that appear are all options for the software to obtain wifi or mobile data, and then selectively turn off the mobile data acquisition function of the software according to their own needs, it should be noted that: turn off the software to obtain mobile data, and it is impossible to connect to the network when you open the mobile data again and use the software.

Think about it, is there any malware installed in the past few days?

Or, you have set up automatic network switching in WLAN advanced settings: go to mobile phone settings - WLAN - click "Menu" to enter advanced settings - automatic network switching (automatic switching between WLAN and mobile network), and cancel this option.

It may be that there is a virus software that automatically opens, and the general mobile phone will not open the data.

This could be an issue with your setup.
