IOS 9 Cellular Data Usage Restrictions not working

Hello, I just updated several devices to IOS 9 and I noticed the Cellular Data Usage Restrictions are turned on. However, when I check the Cellular settings I am able to make changes under User Cellular Data for section. This is the same behavior with all upgraded devices I have. Is this a known issue?


Thanks for your help with cap data plan having this feature working is critical for my family plan and devices.

I am having this issue as well for enterprise. After updating a couple supervised devices to iOS 9 the cellular settings are supposed to be restricted from being changed but this it's only half true. In iOS 9.0.0, when you shut off the items that you do not want working over cellular data and changes are not allowed for cellular data, the items that were already shut off at the time the restriction was engaged will stay off, even though they toggle back to green.


For example, let's say you toggled Music to not work over cellular data, then apply the restriction for cellular data changes, you'll still be able to toggle Music back over to work on cellular data so it APPEARS that it is back on, but as soon as you move away from the Cellular menu and come back Music will show as shut off for cellular data.


While this is really great for things that you already have shut off and restricted it's a real problem for things you NEED to have working over cellular data. For example, let's say that the App Store is something that you want to work over cellular data. If it the App Store is shut off after the restriction is applied, it is going to stay off until it is turned back on by the user.


So basically, any apps that you shut off in Cellular Data at the time the restriction to not allow changes was applied will stay OFF, even though the user thinks they toggled it to ON. Any apps that you leave ON in Cellular Data can be turned OFF by the user or turned back ON.


This is a real problem if you need something to stay ON.

I had this problem, too, but I seem to have found a way to get it to work again. I had to go into Settings>General>Restrictions and then disable restrictions. Restart the iPhone. Set all of the settings that you want to be "locked" after reapplying the restrictions. Then go back in and enable restrictions again. Now, when I go back to Cellular Data, the apps' toggle switches below are now grayed out.

Just tried it. Didn't work for me.

It may seem like it worked but if you close "Settings" and then open it again and go to cellular data the toggles will no longer be greyed out

Quite disappointing to learn that 9.2 has not fixed the restriction settings on cellular data; even with restrictions enabled users can change cellular data settings.


I don't think it's worth doing a bug report. I recently read that Apple has vast numbers of unmanaged bug reports, it is a waste of time for us to submit more. We need a celebrity to complain about this bug.


I do think that, contrary to what is often repeated here, very long discussion threads do get some attention. Perhaps if we get his one to 45 pages the bug will make it to a March 2016 update, or at least be part of the iOS 10 queue.

There has never been a way to manage WiFi data usage. There should be a way to control cellular data usage SETTINGS which is not working, and which is what this thread is about.

If an app is taken off from memory by force quitting - then that is the way to make to sure the app does not use data anymore. Toggling cellular restriction is broken so is the terminate but not stay resident options for non-native apps. These 2 x iOS underlying features appears to be broken in iOS 9 update. It is immaterial whether the data usage is from cellular (3G/LTE) or wifi (802.11b/g) hardware interfaces of the phone.
