Apple iPhone - Turn Cellular Data On / Off

Here's how to turn mobile data for your iPhone on or off.
Some apps on your Apple® iPhone® depend upon background data (transferring data when not directly in use). Restricting background data may cause those apps to stop functioning unless a Wi-Fi connection is available.
  1. From a Home screen, navigate:
    Settings Settings icon
    Cellular
    .
    If an app isn't available on your Home screen, swipe left to access the App Library.
  2. Tap the
    Cellular Data switch
     to turn on Switch On or off Switch Off.
  3. To verify the data setting for a specific service, scroll down to the 'Use Cellular Data For' section.
    Cellular data can be turned on or off by the specific service (e.g., App Store®, Mail, Music, etc.).
For assistance with turning data on or off for individual apps, refer to Manage Data Usage.
