Part 1. What Contributed to Cellular Data Not Working

Quite a lot of iPhone and iPad owners have recently found out that their cellular data feature in their Apple devices are failing to work shortly after updating to the latest iOS version, iOS 11. The origin of these cellular data connection issue is usually brought about in a few several ways.

Sometimes, due to the cellular network itself, the mobile phone’s network straight up fails to send data or access to the internet whenever the iPhone or iPad is connected to the cellular network. Often times, when an application is experiencing some bug due to maybe latest application updates from the App store, cellular data function is also common to disconnect, resulting for the users to uninstall and install the application again from the App Store.

Moreover, in most cases, sometimes owners tend to forget to turn their cellular data back on whenever they did turn it off for some reason. However, in cases like Apple software update, it can be more complicated to fix, and sometimes users are forced to downgrade to the earlier version of their iPhone’s or iPad’s iOS system, back when all these failures have not occurred yet.

The latest iOS 11 software update offers quite a few numbers of remarkable functions in order to make improvements for the user’s experience. However, no matter how great the update may be, it still carries a couple of inevitable problems. And one of those, the most common one, is when cellular data is not working.

In case you are currently in trouble of cellular data failures or mobile network connection errors when you performed a system update on your device, you can troubleshoot and fix the problem by following the guides we are going to lay out below:

  1. Make sure Cellular Data function on your Apple device is enabled.
  2. Check your device’s Cellular Data by setting.
  3. Check if the cellular data is turned ON.
  4. Reset the device’s Network Settings back to its Default.
  5. Look for a Cellular Update.

Method 1. Make sure Cellular Data function on your Apple device is enabled.

The common mistake of most users is jumping to conclusion. Whenever there is something going wrong with their device, they immediately jump to conclusions that their devices are already at its peak and that it needs replacement already. No, it is not necessarily like that. Most of the times, it is just an overlooked problem that makes the users think the problem is too huge to handle when in fact, it can just be easily solved by carefully checking their device.

Method 2. Check your device’s Cellular Data by setting.

Going to the Settings application.

Find the “Cellular” option as soon as the Settings app is launched.

If the switch next to the “Cellular Data” is turned OFF, turn it back ON by sliding to the switch to the left.

Then, make sure that the apps you wish to use with a cellular data connection are turned ON as well. You can check it by scrolling a bit, and you will find a list of applications and beside them is a switch to turn OFF and ON depending on your choice whether to use cellular data on them or not.

Then, you can just simply close the Settings and check if the cellular data Is already working.

Disable Cellular Data

Method 3. Another alternative on how to check if the cellular data is turned ON is by:

Swiping to open the Control Center of the device where a bunch of icons will be shown.At the top left corner, put together in a group of icons along with the Airplane mode icon, Wi-Fi, and Bluetooth, you will find a “Signal” icon which is the icon for Cellular Data. IF that “Signal” icon is colored grey, then it simply means it is turned OFF. Just simply tap the “Signal” icon to turn it back ON. If it is successfully turned ON, the icon will turn green.

Method 4. Reset the device’s Network Settings back to its Default.

If the method above did not help in solving the “cellular data not working” issue, then chances are you unconsciously altered a setting in your network. This happens sometimes, though, so it is a very common issue. In case there is an altered setting in the Network Settings, it can easily be reverted back to its default by:

Opening the Settings application and going to the General option.

Under the General option, tap “Reset”.

In the Reset option, you will be presented with three options: Reset All Settings, Erase All Content and Settings, and Reset Network Settings.

Choose the Reset Network Settings. Be careful in tapping the right option because if you happen to accidentally tap “Reset All Settings” option, chances are you will wipe out all the Settings there is on your device. Worst, if you happen to tap the “Erase All Content and Settings” option, that means all your data will be wiped out, leaving your device with a “fresh” start.

Once you tap Reset Network Settings option, a confirmation passcode will be needed, asking for the action to be legit and okay. Simply enter your passcodes.

Then, close the Settings and return back Home.

Turn the iPhone or iPad by holding down the Power button.

Wait for at least 10 seconds before turning the device back on again.

Now, you will be able to check if the cellular data is working again. Should the device’s cellular data be not working still, then you might need to check the third method.
