Before we begin, make sure you have set up Screen Time on your iPhone or iPad. According to your choice, enable or disable the Mobile Data option from the Control Center. After enabling Restrictions, this will be grayed out (and thus kids/other people can not change it).
How to restrict cellular data with Screen Time on iPhone and iPad
Now open the Control Center (by swiping down from the top right corner on iPhone with Face ID and swiping up from the bottom of the screen on iPhone with the Home Button). You will see that you can not tap and make changes to the mobile data icon. This does the job when you give your iPhone to a kid or someone who is not tech-savvy. But you or anyone can always go to the Settings app and make changes (enable or disable) to Cellular data settings. However, if you want to completely restrict cellular data for a particular app, then you can turn off cellular data for specific app. Signing off… I hope you learned how to wisely use mobile data on your iPhone. Just make sure not to forget your Screen Time password. Finally, besides completely restricting cellular data, you may choose to enable Low Data Mode.
