Cellular data is one of the most important features of an iPhone. It allows you to access the internet, make calls, and send messages when you don’t have Wi-Fi access. But what happens when your cellular data stops working? Panic mode sets in. Worry not. In this article, I’ll show you how to fix iPhone 14 Pro Max cellular data problem for good.

How to fix cellular data not working on iPhone 14 Pro Max issue

1. Check your cellular data settings

Sometimes your cellular data settings can get messed up, so it’s worth checking to make sure everything is in order. Go to Settings > Cellular and make sure that Cellular Data is turned on. If it’s already turned on, try turning it off and then back on again.

You’ll also want to make sure cellular data for specific apps is enabled. To turn on cellular data access for specific apps, you need to find the ”Cellular Data” section. Once you’re there, you will see a list of all the apps that you have installed on your phone that are capable of using cellular data. You can then turn on cellular data access for specific apps by toggling the switch next to them. If the switch is green, that means the app is allowed to use cellular data. If it’s gray, that means the app is not allowed to use cellular data and will only work when you are connected to Wi-Fi.

2. Check your data plan

The next thing you should check is your data plan. Yes, I know this is a painful subject for some of us who have been known to binge-watch entire seasons of our favorite TV shows on our phones while ignoring the warnings from our service provider that we’re about to exceed our data limit. But the fact is, if you’ve used up all of your data, your cellular data won’t work until your plan resets.

To check your data usage, go to Settings > Cellular and look under Cellular Data. If you’ve exceeded your limit, you can either wait until your plan resets (which can be a painful experience for those of us who have no self-control when it comes to our phone usage) or you can upgrade to a higher data plan.

3. Make sure you are in an area with network coverage

If your data plan is fine, the next thing to check is your location. Are you in an area with network coverage? Sometimes, even if your iPhone 14 Pro Max says you have cellular data, you may not actually be in a spot with good network coverage. This can happen in rural areas or in buildings with thick walls. Try moving to a different area or moving closer to a window to get better signal.

4. Toggle Airplane Mode

Another solution to try if cellular data is not working on your iPhone 14 Pro Max is to toggle airplane mode on and off. This might seem like a strange solution, but trust me, it works. Sometimes your phone just needs a little kick in the pants to get things working again. To toggle airplane mode, swipe up from the top right corner of your screen to access the Control Center, and tap the airplane icon. Wait a few seconds, then tap it again to turn it off. This should reset your cellular data and get you back up and running.

5.Restart your iPhone

When in doubt, restart your iPhone. It’s like hitting the reset button on your computer. It clears out any glitches and bugs that might be causing your iPhone to misbehave. This method might seem too simple to work, but you’d be surprised how often it actually does the trick.

To turn off your iPhone, press and hold the Side button and either of the volume buttons until the ”slide to power off” option appears. Swipe the slider to the right to power off your device. Once it’s off, wait a few seconds and then turn it back on by pressing and holding the Side button.

6. Check for software updates

Sometimes the problem of cellular data not working on iPhone 14 Pro can be caused by a bug in the software. Thankfully, Apple regularly releases software updates that fix bugs and improve performance, so it’s worth checking to see if there’s a new update available.

To check for software updates, go to Settings > General > Software Update. If there’s a new update available, download and install it.

7. Check for a carrier settings update

Carrier settings are files that contain important information about your carrier’s network, such as the APN (Access Point Name) settings. Sometimes, iPhone 14 Pro Max cellular data issues can be caused by outdated or incorrect carrier settings. To check for a carrier settings update, go to Settings > General > About. If there is an update available, you should see a notification at the top of the screen. Tap on it to download and install the update. Just make sure you’re connected to Wi-Fi before you start the update.

8. Check your SIM card

If your iPhone 14 Pro Max has a physical SIM card, the next step in fixing cellular data issue is to check your SIM card. It’s the little piece of plastic that houses your phone number and carrier information. Think of it as your iPhone’s ID card. Without it, your iPhone won’t be able to connect to the cellular network.

To check your SIM card, you need to take it out and put it back in. Yes, it’s that simple. But before you do that, make sure your iPhone is turned off. You don’t want to mess with the SIM card while your iPhone is still on. It’s like trying to change a tire while driving your car. Not a good idea.

Now, locate the SIM card slot on your iPhone. It’s located on the left side of the device. Use a SIM ejector tool or a paperclip to open the SIM card tray. Gently remove the SIM card and inspect it for any damage. If it looks fine, put it back in the tray and slide it back into your iPhone. Turn your iPhone back on and check if your cellular data is working. If it’s still not working, move on to the next step.

9. Reset your network settings

If the above solutions didn’t do the trick, you might need to reset your network settings. Sometimes, iPhone 14 Pro Max cellular data issues can be caused by corrupted network settings on your phone.

Please note: this will erase all saved Wi-Fi passwords and other network settings, so you’ll need to reconnect to Wi-Fi networks and re-enter passwords. But it can help reset your cellular connection and fix any issues.

To reset your network settings, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. You’ll be prompted to enter your passcode and then confirm that you want to reset your network settings.

10. Contact your carrier

If none of the above solutions have worked, it might be time to contact your carrier. They’ll be able to check if there are any issues with your account or network and can troubleshoot the problem further. Before you contact them, make sure to have your account information and iPhone details ready, as they will likely ask for these. You can contact your carrier by phone, email, or chat, depending on their available support channels. Don’t be afraid to give them a call, because sometimes the solution to your problem is just a phone call away.


Cellular data not working on iPhone 14 Pro Max can be frustrating, but it doesn’t have to ruin your day. By following these troubleshooting tips, you’ll hopefully be able to fix the problem and get back to enjoying all that the internet has to offer.
