Managing your data usage on an iPhone running iOS 9 is crucial, especially if you want to control how much cellular data your apps consume. Disabling cellular data for specific apps helps you save on data plans, prevent unwanted charges, and extend your device’s battery life. If you’re looking to restrict an app from using cellular data without affecting Wi-Fi connectivity, this step-by-step guide will walk you through the process. Before you start, ensure your iPhone is updated to iOS 9, and you know which app you want to restrict from using cellular data.
What You’ll Need
- An iPhone running iOS 9
- Access to the device with your passcode or Touch ID enabled
- The app for which you want to disable cellular data (pre-installed or downloaded from App Store)
Step-by-Step
- Unlock your iPhone and go to the Home screen.
- Open the Settings app. This is the gear-shaped icon typically found on your home screen.
- Scroll down and tap on “Cellular”. This option manages your cellular data settings.
- Within the Cellular menu, scroll down to find the list of apps under “Use Cellular Data For”.
- Locate the app for which you want to disable cellular data. You will see a toggle switch next to each app.
- Tap the toggle switch next to the app to turn it off. When disabled, the switch will turn from green to gray, indicating that the app cannot use cellular data.
- Exit Settings. Your changes are saved automatically, so no need to tap any save button.
- Test the setup by opening the app and attempting to use data. It should now only work when connected to Wi-Fi.
Common Mistakes
- Disabling cellular data for the wrong app—double-check the app name before toggling.
- Forgetting to toggle the switch back on if you want to re-enable cellular data later.
- Not updating to iOS 9, which might cause the settings to look different or be unavailable.
- Confusing Wi-Fi and cellular settings; remember, this method only affects cellular data.
- Trying to disable cellular data through app settings within the app itself—this is not possible on iOS.
Tips
- If you want to disable cellular data for multiple apps, repeat the toggle process for each app.
- Use this feature to control data-heavy apps like streaming services or social media.
- To quickly identify data-consuming apps, check your usage stats in Settings > Cellular.
- If you want to disable all cellular data temporarily, toggle the main switch at the top of the Cellular menu.
- Remember, disabling cellular data only affects data transfer; calls and texts over cellular are unaffected.
Troubleshooting
If you find that the app still uses cellular data after disabling it:
- Ensure you toggled the switch correctly and that it is turned off (gray).
- Restart your iPhone to ensure settings are properly refreshed.
- Check if the app has any in-app settings to restrict data usage, though this is uncommon on iOS 9.
- Make sure your device is connected to Wi-Fi and not in Airplane Mode.
- If the app continues to use cellular data, consider deleting and reinstalling it to reset permissions.
- Verify that your cellular plan isn’t overriding restrictions—contact your carrier if needed.
If issues persist, resetting network settings might help, but be aware this will erase saved Wi-Fi passwords and VPN settings. To do this, go to Settings > General > Reset > Reset Network Settings.
