How to Prevent Cellular Data Setting Changes on an iPhone

Some apps can use a lot of data if they are running when connected to a cellular network, which can amount to a significant percentage of the monthly data allowance on your cellular phone plan.

Turning off cellular data for an individual app is something that can be accomplished in just a few short steps, but it also means that it can be turned back on just as easily.

So, while turning off cellular data may be a good solution for an adult, it might not be adequate for a child who wants to watch Netflix or listen to Spotify with cellular data.

Fortunately, you can configure the settings on an iPhone so that cellular data settings cannot be changed.

The option for doing so is found in the Restrictions menu, and our guide below will show you how to turn it on.

Block Cellular Data Use Changes in iOS 8

The steps in this guide were performed using an iPhone 6 Plus in iOS 8. These steps will also work for other devices using iOS 8.

Once you have completed these steps, the cellular data settings on the device cannot be changed by anyone who does not have the Restrictions passcode.

So apps that are currently set to use cellular data will continue to do so, while those apps for which cellular data usage is turned off will not be able to access the Internet on a cellular network.

If you want to change the cellular data settings for something on your iPhone, then you will need to return to the restrictions menu and switch the Cellular Data Use option to Allow Changes instead of Don’t Allow Changes.
