The most common signs that your iPhone or iPad’s cellular data isn’t working are:

  • The cellular data network could not be activated. The cellular data icon is grayed out or missing entirely. Wi-Fi is the only way to get data.
  • You have no access to the internet. Your internet is either very sluggish or completely unavailable.
  • Cellular Update Failed: Until your iOS devices are updated, you won’t be able to make or receive phone calls, send or receive text messages (SMS), or use cellular data.

This is merely a small sample of the many error messages you may see.

Why would this happen?

A lot of issues might be causing your cellular data to be unavailable. It might be due to a lack of mobile internet coverage or a weak connection in your location, a physical issue with your iOS device or SIM, a system malfunction after an upgrade, or simply forgetting to switch off Airplane Mode.

How to Fix iOS 15’s Cellular Data Not Working Issue

Now, have a look at these simple ways to permanently cure the “cellular data not functioning” issue on your iPhone or iPad.

Cellular Data Disable and Enable

If your iPhone or iPad’s cellular data isn’t functioning, the first thing you need do is deactivate it and then reactivate it. This is how:


  1. Tap Cellular in the Settings menu.
  2. Toggle the switch to the off position under Cellular Data Options.
  3. Toggle the switch to turn it on if it’s off.

On and off the Airplane Mode


The next thing you should try is turning airplane mode on and off. To do this, go to Settings > Airplane Mode and toggle the switch to the “on” position. After a few seconds, switch it back to “off” and see if your cellular data starts working again.

Restart your computer.

Restarting your smartphone will hopefully resolve any temporary difficulties that are creating a connection difficulty and restore your cellular data.

Simply press and hold the power button to turn it off. Turn your smartphone back on after a few seconds to determine whether the issue has been repaired.


Remove your SIM card and replace it.

If none of the previous methods work, you may try removing and replacing your SIM card. This simple solution often works! Follow these steps to do this:

  1. Turn off your device as described above.
  2. Open the lid of your iPhone or iPad SIM tray using a SIM tool or another method.
  3. Remove and discard your SIM card.
  4. Close the tray and re-insert your SIM card.
  5. Return your gadget to its original state.

It’s possible that your network is down or that your SIM card has been destroyed. If this is the case, contact your service provider and ask for a new SIM card.

Examine your date and time settings.


Sometimes, if the date and time settings are not set correctly, it can cause problems with cellular data. To fix it, just go to Settings > General > Date & Time and make sure that the date and time are set correctly. If they’re not, tap on the “Set Automatically” toggle to turn it on.

If it doesn’t work, go on to the next suggestion!

Look for an update to your carrier’s settings.


Another thing you can try is checking for a carrier settings update. These updates are released by your carrier in order to improve cellular data performance or to fix bugs. To check for an update, go to Settings > General > About and wait to see if there’s an update available. If there is, follow the on-screen instructions to install it.

Turn off LTE.


If you’re having trouble obtaining any cellular data, consider turning off LTE on your smartphone. Go to Settings and hit Cellular Data to do so. Then, next to Enable LTE/4G, turn off the option.

This will certainly make your connection slower, but it will allow you to go back online if none of your other connections are functioning correctly.

Disconnect from the VPN

If your iPhone or iPad isn’t connecting to the internet or cellular data, the first thing you should try is turning off your VPN. To do this, go to Settings > VPN and toggle the switch off. Once you’ve done that, try connecting to the internet again. If it still doesn’t work, move on to the next step.


Make sure your iPhone or iPad is up to date.

If you’re experiencing trouble connecting, there’s a fair chance it’s due to a fault in an older version of iOS that has been resolved in the newest release.

Note: Before installing any software update, Apple highly advises that you back up your iPhone and iPad using iCloud or your computer.


To check for updates, go to your device’s Settings app and choose General. Tap Software Update from there, and if an update is available, download and install it. Reconnect to cellular data when your device has been updated.

Set your network settings to default.

If you’ve tried all of the above solutions and your cellular data is still not working, you may want to try resetting your Network Settings. This will reset ALL of your network settings, including your Wi-Fi settings and VPN & APN settings. To do this,


For iOS or iPadOS 15 or later, go to Settings > General > Transfer or Reset iPhone > Reset and tap on “Reset Network Settings.”

For iOS or iPadOS 14 or earlier, go to Settings > General > Reset and tap on “Reset Network Settings.”

Contact your service provider.

There are occasions when a problem with your account or service arises that only your carrier can resolve. It’s time to make contact with them. They may be able to assist you with troubleshooting or even give you with a new SIM card.
