operational approach
0 1
First, we open the "Settings" function of the mobile phone, select the "Traffic Management" option in the settings function, and click Open.
Package setting: I use a dual card dual standby mobile phone. Select "China Telecom", select "Package Settings" option under China Telecom to open, click "Package Limit/Open Day" and enter the maximum flow of our package. For example, if the package traffic is 500GB, then enter 500GB, and enter 1 on the opening day, that is to say, every month starts with 1. Then set "province and city", and the operator will automatically calibrate it regularly.

Thirdly, set "Reminder Settings" and select "Monthly Traffic Limit". We will enter the maximum flow of the package, such as 500GB, and then confirm.
Set "When the flow exceeds the limit" and select "Reminder" or "Disconnect".
Set the "monthly used flow reminder" to 80%, and the system will automatically remind you when the monthly flow reaches 80% of the monthly meteor limit.
Set "Daily Used Traffic Reminder", which is the same as "Monthly Used Traffic Reminder" and can be set by yourself.
03
Finally, set the "screen lock traffic reminder" and select on, so that every time we turn on the screen, we will receive a system prompt about the traffic usage during the screen lock process.
Set the notification bar to display the traffic information, and select the on state, so that we can check the traffic usage at any time.
Usually, we can also check the traffic usage through the drop-down notification on the mobile phone screen.
