The simplest way to get rid of the cellular update failed message is by switching your iPhone’s Airplane Mode on and off.
Toggling Airplane Mode corrects any minor cellular connectivity issues by resetting the signals.
Here’s how you switch Airplane Mode on and off on your iPhone:
- First, go to the Control Center of your iPhone.

Turn Off Wi-Fi Calling and Voice LTE
Next, you can try to turn off Wi-Fi calling and Voice LTE features. Again, there’s no science behind this solution, but it has worked for people who faced the iPhone cellular update issue before.
Here’s how you can do so:
- First, open your Settings app and tap the “Cellular” options. Once you find the Wi-Fi calling feature, enable it.
- If it’s already enabled, toggle with the “Wi-Fi Calling on This Phone” feature before disabling it entirely.
- Then, go back into your Cellular settings and select “Cellular Data Options.” Next, tap “Enable LTE” before switching the settings to “Data Only.”
- This will turn off your iPhone’s Voice LTE feature. Now, try to update your cellular settings again.
Turn Cellular Data On and Off
If that doesn’t help either, here’s another quick and simple way to get rid of the iPhone Cellular Update Failed error.
All you have to do is turn your cellular data on and off. In Settings, you’ll find the Cellular section, in which you can turn cellular data off.
After doing that, you can check if the update is working or not. It may be that your cellular network provider is having some connectivity issues; turning your data on and off can help reset the cellular connection.
Check iOS Update
Another reason your cellular update failed on iPhone could be that a software update is pending. So, don’t forget to check your iPhone’s latest iOS version software update before you take any further steps.
Here’s how you can do so:

Reinstall the SIM Card
Probably, your SIM card isn’t inserted correctly, resulting in a poor connection to your cellular data.
To get rid of the window that says “Cellular Update Failed” on your iPhone, make sure your SIM card isn’t loose, damaged, or placed incorrectly.
For this step, you’ll need a SIM card ejector tool.
Take your SIM card out using a SIM Card eject tool and look for any signs of damage. If it seems like it’s in good condition, place it back into the SIM card tray but ensure that the microcontroller is faced down. Plus, the SIM card shouldn’t be loose.
Then, slide the SIM tray back into the iPhone, lock it, and try to turn your data on again.
Check Carrier Settings Update
The carrier settings in your iPhone deal with the improvement of the carrier’s cellular network and its connectivity. If there’s a pending carrier settings update you haven’t installed, it may display the “Cellular Update Failed” message.
Here’s how you can check for any cell phone carrier settings updates in your iPhone:
- First, open your Settings app and select About.
- If there’s a carrier update available for your device, you’ll see a pop-up message that says, “Carrier Settings Update.”
- Tap on “Update” to update carrier settings.
- Once the update has been installed completely, try connecting your data again.
Reset Network Settings
It may be that the problem lies in the connection of the cellular networks, but a quick network reset should fix that for you. While your device data will stay intact, all the network settings will be changed to default.
By doing so, you’ll be able to get rid of the interruption that’s causing the Cellular Update Failed error. Here’s you can reset network settings:
- Open your Settings app and select “General.”
- Tap “Reset” and select the “Reset Network Settings” option.
- Once you’ve confirmed the reset, you can let your iPhone finish the process.
- After the network settings reset, try to reconnect your mobile data.
Reinstall iPhone System
This step may seem tedious, but it’s worth it if you want access to your cell data once again. Bringing your iPhone to its original factory condition will get rid of any glitches or errors you might have been dealing with.
Here’s how you can reinstall your iPhone system:
- Connect your iPhone to your Mac via USB and launch the iTunes app.
- Select your iPhone in the Devices section and click the “Summary” tab.
- When you tap the “Restore iPhone” option, a confirmation pop-up window will show up.
- Select “Restore” to confirm the process and agree with the license agreement.
- Then, a new iOS system will download and install into your iPhone, which will now restart.
- You can now use the “Slide to Set Up” option to launch the Setup Assistant. It’ll give you instructions that you can follow to set up your iPhone.
- Once your iPhone is all set up, you can try to connect your mobile data once again.
Factory Reset Your iPhone
If all else fails, you can simply factory reset your iPhone.
To do so, you can follow these simple steps:
