IOS 9 Cellular Data Usage Restrictions not working

Same here on 3 different Iphone 4S upgraded to 9.0.1 just now. All have the same problem. In a previous IOS, connecting to iCloud caused this problem. I had this problem on phones connected to ICloud but didn't have it on phones not connected to iCloud.

I phoned service provider regarding this issue. We tried to reset network settings and reset all settings but it didn't fix the problem. I had been told to reset to factory setting and make sure to back it up first to itunes. I'm not comfortable doing it since it will be a hassle downloading/setting up the app's contents again. Agent forwarded the issue to Apple to fix this problem....no resolution yet.

If you don't have Apple Care....better yet to call your service provider about this issue so they can raise it with Apple and make some resolution to this.

@jspence444 - Thanks for your update. Yes, it seems logical that the update 9.0.1 must have been far into development - so as to go back for the bug we are experiencing. I have just received the ios update, not yet installed - but reading from all the experiences it will not be fixing the bug. 😟.

Let's hope they come out with another update soon.

Keep us posted.

iphone 5s, updated ios 9.0.1, no change in settings. Problem still persists.

Same issue here. iOS9.01 doesn't fix the problem 😟

I Have the 5c and I restored my phone completely then updated all the apps and it's still not working.

Same problem over here... Tried everything as well, nothing helped... Wanting to throw again my iphone! Hope that Apple comes up with a solution real fast!!

Iphone 5S, model ME432NF/A

Same issue here on a iPhone 6 with 9.1 Beta. Tried going back to 9.0.1 still same issue.

I already fix it. I just use restore phone and when it said do you want to backup setting i press no. After complete restore, my phone is good to go. if i restore the backup, then the problem will happen again. So i dont use the backup. Instead i use anytrans software to open up backup bundle that i save and get my thing such as picture and document. Then i use sync to put it back to my phone and install back all my apps. So right now. The bug is gone even it take hours to test certain thing. But until right now i still have no prblem with my phone. this is surely the last time i update ios without checking if there any problem. Oh yeah i use the ios 9.0.0 not the latest one

I Am also experiencing this problem Running iOS 9.0.1 (13A404) on iPhone 4s MD237X/A. I'm in Australia.

Affecting all apps not just third party apps. Very very annoying!

I just downloaded the fix release of iOS 9.0.1 and it didn't fix the issue!

This bug has turned my iPhone into a Nokia 1100... I really hope they fix this urgently.

Everyone: please submit a bug report at http://www.apple.com/feedback/iphone.html Make the subject: Cellular Data changes not saving Hopefully they will see it and issue a 9.0.2 fix ASAP.

IiPhone 5s here same issues as everyone else. I have tried all posted and Apple suggested resolution to no avail. sadly because I had almost all my apps turned off to cellular data when I updated even native Apple apps (Apple store, Music, map, Safari, etc )are useless unless I'm on wifi. They need to really look into this very frustrating!!!

Hey guys I finally managed to FIX the problem with the cellular data toggle on/off bug.

So I tried many things before finally getting to the actual solution to the problem.

What I did was while using iOS 9.0.1, I wiped it all out and restored my iPhone 6 from a iOS 8.4 backup from 17/09/2015 when I still didn't have iOS9 (mainly because of another Apple bug with updating to the new software which took me 4 days to do). So when I got into the cellular data page I could change the button between on and off without the software reverting my changes.

I hope this was helpful for all the struggling ones! 😀

This issue just started yesterday for me, I tried every tech hack I know to fix it, but it won't budge. iOS 9 bug for sure. Don't know how to restore phone to iOS 8 or whatever it was.
