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.

Hi all,


A colleague at work was kind enough to offer his personal hotspot for me to reset my phone. I've reset my phone using General > Reset > "Erase all content and settings" without connecting it to iTunes. After the wipe, I am unable to reproduce the symptoms of this issue.


Things I have tried with a fresh install (no App Store downloads)

  • Turned off cellular data for all apps individually
  • Enabled restrictions, disable Carplay and In-app purchases
  • Turned on cellular data for Settings app to update settings with iCloud account
  • Turned off cellular data for Settings app

After completing these steps, the problem does not occur.


Things to try to reproduce the issue:

  • Install App Store applications and modify cellular data settings
  • Connect to iTunes to sync music, then modify cellular data settings
  • Connect to WiFi and disable cellular data for all apps individually, then turn off WiFi and modify cellular data settings

These are what I did yesterday that led to the issue resurfacing.


Anyone with any other ideas to reproduce the issue, please feel free to state them. Without a reliable means to reproduce the issue, I doubt Apple developers can do anything about it.

I upgraded to iOS 9 on Saturday and started having this issue on Monday. I called Apple and they had me do a reset for network and all settings. Nothing worked. I went to my Verizon store and they gave me a new SIM card. That didn't work either. Fortunately, my phone is still under warranty and they are sending me a new phone. I will NOT be upgrading to iOS 9 until they release an update to fix this. I don't normally update to a new iOS until they have worked out all the kinks and this is why. Lesson learned.

@Bengohyp,

i wouldn't discount this as an issue seeing as so many other people have experienced it, and you yourself experienced it on a clean install the other day. All this suggests is that it's an inconsistent issue, based on some kind of variable, which we sort of already knew. For example, some people are experiencing this only on their iPhone, others on their iPad, I'm experiencing it on my iPhone but not my iPad.


@AlokekumarIndia glad to hear it's considered a known issue at this point.

UK apple support just confirmed it is a bug, and advised that software engineering is working on a fix. He said he hoped the fix would be ready within a couple of days, but wouldn't give an exact time frame.


Apparently when you toggle those switches it does some sort of verification with a server (no idea why), and the verification is failing - hence it returns the switch to the off state.
