IOS 9 Cellular Data Usage Restrictions not working

Hi all,

I'm also facing the same problem.

I did a clean install last night and turned off cellular data for all apps and they stayed off. Then I configured the iPhone's settings (e.g. set up Mail, connect to iCloud, turn on Restrictions). This morning, when I tried to enable cellular data for individual apps as I start to use them, the issue resurfaced.

My guess is that Restrictions cannot be turned "On" in iOS 9. Even after turning Restrictions "Off" and performing a hard reset of the phone, the issue does not go away. This may explain why restoring does not resolve the issue.

I will perform another wipe tonight to test. If anyone is willing to test this out, that'll be great.

Been working on fixing mine since last Friday. Wiped it clean several times. Spent about 15 hours on this so far with AppleCare, Apple Support, Apple Store and Verizon. Today, Apple support told me to Erase All and then set up as new phone to test. Problem was NOT there. So they told me to Erase All again and restore the cloud backup that I did last night. Guess what? Problem came right back. Totally asinine!!

So @bengohyp, the issue resurfaced after you did the clean install? Please confirm.

This is important because Apple support for software-based issues usually includes telling customers to restore their phone and do a clean install. It's important to note if that did or did not fix the issue.

Hey @ dglis30731, when you did the clean install(s), did you try toggling the switches on and off, or did you leave them on and try using apps with cellular data?

Also, to what extent did you set up the phone before doing the testing? For example, did you set up mail accounts, sign into iCloud and/or iTunes?

One user above (bengohyp) seemed to suggest that the problem resurfaced on a clean install after they started setting up their phone, signing into accounts, etc.

Hi @jspence444,

Yes, the issue resurfaced after I did the clean install. However, it wasn't immediate. I was able to toggle "Off" individual apps after the clean install last night. Then I changed some other settings and noticed this morning that I wasn't able to toggle "On" individual apps.

I do not have access to iTunes at work and therefore cannot proceed to test further. I also turned off cellular data for the Settings app and cannot perform a General > Reset > Erase All Content and Settings to test.

Further points to note: 1. This only affects Apple apps for me. For installed applications like Telegram messenger or Whatsapp, the cellular data toggle works from the cellular data menu as well as the app's own settings menu at the bottom of the settings page. 2. Resetting settings from the General > Reset > Reset All Settings or Reset Network Settings does not solve the issue.

Thanks for clarifying that @bengohyp. The fact that the issue resurfaced after you did a clean install strongly suggests we need a point update (e.g. iOS 9.0.1) to fix this issue, and that wiping and reinstalling does not address the issue permanently.

Honestly, at this point I don't remember. I've done so many steps I've lost my place. I should have kept a log. I think, but won't swear to it, that I checked the toggles immediately and they were off and wouldn't stay on again. So I'm guessing that if I just set it up as "new", I might be ok but I don't want to lose everything. Thank you for keeping us in the loop. I agree about waiting for 9.0.1 and already posted that on my Facebook page to warn my friends and family.

New info: our issue resembles a similar issue from iOS 7. See this thread for more info: iOS 7 cellular data settings won't save on iPhone 4s???

I Remember having the same issue when iOS 7 was first brought out. You think this problem wouldn't resurface 2 years later yet again! All these high baller Apple engineers or whatever the **** they are....#overpayed #eggheads This is a huge issue and there's no reason for something like this to fall through the cracks. #notokay #getyourshittogetheralready #howcanyouhavethesameissuetwice

Let's help the Apple engineers so they can fix it faster.

(1) Everybody turn on the option in Settings to send diagnostic data to Apple

(2) Leave a comment in this thread with your iPhone/iPad model you're experiencing the problem on.

I'm on the iPhone 6, model A1549 (64GB, GSM, space grey) but not on my iPad Air, model A1475 (64GB, cellular space grey).

Diagnostics on ✔️

I'm using the iPhone 6 Plus, model MGCM2LL/A (16GB).

I'm using the iPhone 5S, model A1530.

Diagnostics are on but cellular data cannot be turned on for Settings 😐

I Am so annoyed about this cellular data thing being messed up!! Tried using one of my apps to while I was not in wifi and could not use my app. Did the whole trying to turn it on and it just shuts back off!! I really hope this is something they will fix!! i have been told not to update devices right away cause stuff like this always happens!! And hopefully by waiting it usually gets fixed if there's anything wrong!! This is one update I wish I did not do!! My phone also works slower and dies a lot faster!! I hope those APPLE people read all the messages and comments and fixes this ASAP!! We speand spend so much money on all these darn devices and they go and mess them up!!!

Diagnostics ON

iPhone 6, model MG472HN/A, country India

Facing the toggle issue. Not able to toggle the apps in cellular data after upgrade to ios9.

Goodmorning,

I have the same issue on my iPhone 5s. I wanted to use iTunes to download a song but iOS prevented me to turn on mobile data usage for the iTunes app.

I cannot believe that a bug like this has made it to the end user.

Beside this bad bug, my iPhone frequently freezes or even reboots for no reason.

Apple, keep your quality under control. Only 6 months to go before I can go to a new phone. Will that be Apple? Unfortunately, I'm not so sure anymore.
