Restrict background data usage by app (Android 7.0 & lower)

Important: Restricting background data usage can affect an app's performance. For example, you could get no messages from an app until you next open that app.

Before restricting data usage from your phone's Settings app, check whether you can restrict data usage from the app's own settings menu.

  1. Open your phone's Settings app.
  2. Tap Network & internet and then Data usage.
  3. Tap Mobile data usage.
  4. To find the app, scroll down.
  5. To see more details and options, tap the app's name.
    • "Total" is this app's data usage for the cycle.
    • "Foreground" is how much data the app has used while you’re using it.
    • "Background" is how much data the app has used while you’re not using it.
  6. Change background mobile data usage.
    • To restrict background data usage for this app, turn off Background data.
    • To allow unrestricted mobile data usage when data saver is on, turn on Unrestricted data usage.

Important: Data roaming may be the only way to connect to the internet in some places. Some carriers charge extra for data roaming.

  1. Open your phone's Settings app.
  2. Tap Network & internet and then Mobile network.

Troubleshoot mobile data usage settings

Important: Your phone measures the data usage shown in your phone’s Settings app. Some carriers measure usage differently. We recommend checking with your carrier for its measurements and your plan limits.

If you see only Wi-Fi settings
  1. Check that you have a SIM card inserted in your device.
  2. Check that you have mobile data.
If your phone has more than one SIM

Check that you've assigned mobile data usage to one SIM. Learn how to assign activities to SIMs.
