6. Check for an iOS update

If none of the above steps helped you fix iOS 17 cellular data problem, there are still some solutions you can try.

Apple has been on a rapid pace with new software updates on a seemingly bi-weekly basis. There are bug fixes and additional software features that are added with these updates. And those bug fixes could be just the key for getting your iPhone cellular data to work again.

1. Start the Settings app.
2. Go to General.
3. Tap Software Update.
4. If an update is available, tap Download and Install.
5. Type in your passcode when prompted.

7. Reset Network Settings

If none of the options above work, it may mean some extraneous setting was changed in the process of iOS 17 update. It is likely related to the network, so resetting your network settings to factory defaults might fix the issue.

1. Start the Settings app.
2. Go to General.
3. Scroll down and tap Transfer or Reset iPhone.
4. Tap Reset.
5. Select Reset Network Settings.
6. Type in your passcode, when prompted.
7. Tap Confirm.

Once completed, your iPhone will forget any network settings that you had previously configured. This includes any Wi-Fi networks, or any other data settings that you had created in the Settings app.

8. Disable VPN

If you are using or are subscribed to a VPN on your iPhone, in some rare cases, it can also block your cellular signal from connecting. Having a VPN can be used for things like staying safe on public Wi-Fi or bypassing geo-restricted viewing restrictions. Should you find that you are having trouble connecting to your cellular signal after iOS 17 update, disable your VPN temporarily and see if that helps resolve the connection issue.

It might also help to disable the VPN by going into the VPN settings and toggling your app of choice to “off” and then doing a forced restart. With the forced restart, you can be sure that you are completely disconnected. Now see if the cellular signal returns, and if not, move on to the next solution.

9. Factory reset iPhone

If all else fails to resolve mobile data problem on your iOS 17 device, go ahead and factory reset your iPhone. This will erase everything on your iPhone and bring all settings to factory defaults. This means your iPhone will be left like the first time you turned it on (software-wise).

This fixes pretty much any software issue you may encounter. It is the best solution to many issues, but it should be used as a last resort due to the inconveniences deleting all data entails.

Go to settings > General transfer or reset iPhone > erase all content and settings.
