Q: IOS 9 Cellular Data Usage Restrictions not working

This is still an ongoing issue and Apples silence on the matter is deafening. I know they don't respond on these forums but this is a gaping hole in iOS settings and needs fixing!

I have a rudimentary fix for this however but will only be useful to a handful of people in specific situation. That being if you have given your kids a phone and don't want them to access data for fear of uncapped tariffs racking up huge bills.

Go into the mobile data setting > mobile data network and then erase the APN  address under the mobile data section at the top. Make a note of it so you can re enter if need be later on.

This will however stop ALL mobile data as there is no server address for your phone to access. Another issue is a carrier settings update may get pushed to the phone and update the APN itself so you will still have to keep an eye on it a bit but it will help to stop mobile data being used for the most part.

I do this on both my kids phones as iOS ***** big time as we all know and my crappy carrier refuses to put a cap in place.

This worked for me. I wish I knew that there was a bug in the before my minor child left for a field trip 1000 miles away.  Somehow her find iphone and life360 apps weren't working.  Now I know why.

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.

This issue is fixed in iOS 9.3 as far as I can tell. It works for me.

Having the same issue!

Very helpful and this resolved the issue on my IPHONE5 which was causing so much issues. This really helps to open up and then lock the settings.

Thanks a ton again.

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.
