1. Download a portable business hall, divided into provinces. You should bring your own province when searching for applications in the app store. In this era when everyone has a smart phone, you don't need to send text messages often to inquire. Just download an app.

2. Enter the handheld business hall and select: mine. In "My", you can see the consumption balance, the consumption amount of the current month, the remaining traffic, and the remaining call time. Click on the remaining traffic here. Select the direction in the remaining flow, so that you can see how much the remaining flow is. But that's not enough. We need to see the details.

3. Click to view the details. After that, you can see exactly what your directional traffic contains. These directed streams will be used for the specified application and will be listed in the details.

4. In addition, some users also have a kind of community-oriented traffic, which can only be used in designated areas, usually in campus packages.
