Exceeding your data allowance can result in additional charges. To stay in control you can quickly and easily monitor how your data is being used on your device. Under the “Data usage” settings of your Android device, all App related data usage is recorded, allowing you to track exactly how your data is being used.
Step 1. From your Android home screen, app drawer, or notification panel, tap the gear shaped icon to open your device’s Settings menu.
Step 2. Select “Data Usage” This will open the Data Usage screen. The screen will then display the overall amount of data used at the top and below in a graph.
Step 3. Select “Mobile Data Usage” to check the overall data amount you've used for a certain period. Enter the period from which you would like to check your data usage using the drop down box at the top right corner of the screen then tap “OK.” The changes will be displayed at the top of the screen.
Note: Your Android device will not automatically line the dates up with your monthly billing cycle, so you’ll need to set your billing date manually.
Step 4. Below the overall data amount used, you will see a list of applications is displayed. This list shows the amount of data used individually by each app.
Step 5. Select an application to check the specific amount of data used.
Step 6. You will be able to see the background data amount used as well as the foreground data used. The foreground data is the data used while you are using the application while the background data used is the data consumed by an application when it’s not being actively used
