5: Reset Network Settings

Resetting network settings can help resolve network issues, such as iPhone cellular data not working problems. While it's a good solution, keep in mind that resetting network settings will also wipe out any stored Wi-Fi passwords, so make sure you have written down or made a note of your saved Wi-Fi password. You'll have to re-enter them after the reset.

To reset network settings, navigate to "Settings" > "General" > "Reset" > "Reset Network Settings." Enter your passcode if required, then confirm your decision.
