Part 2: How to Fix No Cellular Data on iPhone/iPad [Basic]

Fix 1. Check If You’ve Reached Your Cellular Data Limit

The majority of cellular data plans (by almost every network carrier) have daily data limitations. For instance, the most basic plan for your network carrier would allow you to use 1GB of data every day. Once your data usage surpasses the specified limit, the speed would automatically go down and you won’t be able to access online services at the same speed as earlier.

This could also be one of the reasons why you’re unable to connect to cellular data on iPhone 13. So, before everything else, check whether you’ve reached the daily data limit. In this case, you can either buy a dedicated data booster pack or wait until the next day.

Fix 2. Restart Your iPhone

This has been one of the old-school solutions to fix a wide variety of problems on different electronic gadgets. In case something doesn’t work, simply restart the device and hope that it resolves the issue. Well, the same is the case with iPhone 13 as well. In case iPhone 13 cellular data not working on your device, you can simply press the “Power” button and restart your device. This will close all the background applications and you’ll be able to connect to cellular data after the device restarts.

You can also try enabling the Airplane Mode for a while to fix the iOS 15 cellular data not working error. When you turn on the Airplane Mode, all the network services will automatically shut down on your device. And, after you disable it, these services will resume automatically. So, if a random network-related error is causing the problem, this will fix it immediately.

  • Step 1: Bring up the control center by swiping down on the home screen of your iPhone 13.

Fix 5. Re-insert Your SIM Card

Believe it or not, but by simply re-inserting the SIM card in your iPhone 13, you can troubleshoot different types of cellular data errors. When you reinsert the SIM card by removing it for a while, the communication between the device and SIM card resets automatically, which can fix the cellular data not working error as well. So, grab the SIM tool, open the SIM tray, and remove the SIM card from the device. Keep it away for a while and reinsert it to check if still cellular data is not working on iphone 13.

Fix 6. Check for Carrier Updates

Almost every network carrier provider releases regular carrier updates to keep their services in compliance with the latest iOS versions. So, if you have had no luck so far, you can also try checking for network carrier updates. Whenever there are newly available updates, your iPhone 13 will automatically alert you via a Push Notification. Simply click on this notification and the selected updates will get installed on your device instantly.

Fix 7. Check for iOS Updates

To update your iPhone to the latest iOS version, go to “Settings”. Click on “General” and then, tap the “Software Update” option. In case there are any pending software updates, you’ll see them listed here. However, if the screen prompts “your software is up to date”, proceed towards the next solution.

Fix 8. Disable VPN Apps

In some cases, third-party VPNs can also interfere with normal cellular connectivity on your iPhone 13. So, in case you have installed a dedicated VPN solution, it would be better to disable it before connecting to cellular data. Now, if you regularly use a VPN, this would be a temporary walkaround. So, once your device successfully connects to the cellular data, switch to a different VPN service provider to avoid cellular data not working on iPhone 13.

Fix 9. Reset Cellular Data Settings

Resetting the cellular data settings, most commonly known as network settings, is also an effective way to fix the iOS 15 cellular data not working error.

It will take a few minutes for the process to complete. Once it does, check if you are able to connect to cellular data or not.

Fix 10. Factory Reset Your iPhone

In case your iphone still won't connect to cellular data or cellular data is not working on iPhone 13, you can also factory reset your device to troubleshoot the problem. However, make sure to keep this method as your last resort because restoring the device to factory settings will erase everything from the iPhone. So, you should only proceed with this solution if you either don’t have any valuable files on your system or have an iCloud/iTunes backup to restore the files.

Here’s how you can factory reset your iPhone 13 to the default factory settings.

  • Step 1: Again, open the “Settings” app and click on “General”.
  • Step 2: Click the “Reset” button and tap on “Erase All Content & Settings”.

Then, enter your iCloud password to confirm your actions and let the device reset to default settings automatically.

Fix 12. Contact Your Carrier

If none of these solutions work, you might want to contact the network carrier provider to resolve the problem. As we mentioned earlier, cellular data can stop working due to unexpected network-related errors. In this situation, simply reach out to the network service provider and they’ll assist you with an appropriate solution accordingly.

Fix 13. Contact Apple Support

In some situations, it’s quite possible that nothing would work in your favor. If that’s the case, you would have no other option but to contact the official Apple Support team. Ask them “why does my cellular data keep turning off?” and let them diagnose the problem. You can also visit an Apple Repair Center to check if there is any hardware-related damage on your device.
