Parental Controls, also known as Restrictions, allow you to prevent anyone else from making changes to how you use your data on your iPhone. If you are on a tight data plan or choose not to use data, you can lock the ability to change cellular data or background refresh options. You can rest easy knowing your kids — or anyone else — won't be racking up data charges on your bill.
How to block changes to your accounts, cellular data usage, background app refresh, and volume limits on iPhone and iPad
Before you start, you'll need to make sure you have set up Screen Time on your device.
- Launch Settings from the home screen.
- Tap Screen Time.
Tap Content & Privacy Restrictions.
Scroll down and tap on these categories to change their settings:
- Passcode Changes
- Account Changes
- Cellular Data Changes
- Volume Limit
- Do Not Disturb While Driving
- TV Provider
- Background App Activities
Tap Don't Allow.
If you want to allow changes to any of these settings, you can follow these same steps again, and choose to Allow them.
