  • Now, drag the slider to power off your device.
  • After a few seconds, press the “Power” button to restart your iPhone.

Now open FB on cellular data and verify the fix!

Note: You can also reboot your iPhone from the “settings” app. To do this, launch the “Settings” app from the device’s home screen/App Library and go to “General.” To power off the device, choose “Shut Down” at the bottom of the screen and then drag the slider to the left.

  • Tap “All Apps.”
  • Choose “Facebook.”

Check the Device Data Usage Limit

If you’ve set the data usage limit on your Android and have exceeded it, the FB app won’t work on cellular data.

To verify this, go to “Settings,” navigate to “Connection” > “Data Usage,” select “Mobile Data Usage,” and see if the data usage limit is exceeded. To disable this option, untick the box next to “Set Mobile Data Limit.”

If the device’s data usage limit is not exceeded, you may have used up all your data package. To check this, dial a data-checking code provided by your network provider or use the app (if any).

Note: Force stop any process or app running in the background that uses the mobile data and can affect the Facebook app’s performance 

Enable Background Data Usage

This solution is also helpful if the Instagram app is not working on mobile data.

Note: To stabilize the network connection, try enabling and disabling mobile data from the Control Panel or Quick Access menu on your iPhone or Android device.

Reset APN Settings
