Reset Your Network Settings
If you still can’t get your cellular data to work, resetting your iPhone network settings might help. This will delete all your saved network connections so you can start fresh.
Keep in mind that this will also delete all your saved Wi-Fi networks and VPN profiles, so you’ll need to set these up again. VPN profiles are usually easily re-added from the appropriate apps, but make sure you have any important Wi-Fi passwords for your company, school, or home networks on hand. Here’s how you can find them in your iPhone’s Wi-Fi settings if you need to write them down before you proceed.
Once you’re ready, here’s what you need to do:
- Open the Settings app.
- Scroll down and go to General.
- Scroll down to the bottom and select Transfer or Reset iPhone.
- Select Reset.
- Choose Reset Network Settings.
- Enter your passcode.
- Tap on Reset Network Settings to confirm your decision.
Once your iPhone is done resetting your settings, you can try to use your cellular data to see if this does the trick.
