Unable to turn cellular data on for apps

I can confirm a similar problem I've had since iOS 7 all the way to the current iOS 11 (11.1.2) that doesn't allow toggling of individual apps' cellular data setting. Nothing short of a full-wipe-don't-restore-anything-lose-all-your-backed-up-data will restore proper functionality, as nothing else suggested ever works (as you've described pombe).

It's clear that there's an iOS bug that causes the cellular settings file to somehow get 'locked' and rendered either not properly readable and/or writable to change any of the apps settings.

I've tried reaching out to Apple's techs about this issue, and they suggested the usual (unacceptable) wipe-and-try-again-without-restoring-anything, but never heard back after my first response back to them (I think they stopped reading after "That worked" when I replied "That worked but is not a workable solution....").

I may try to reach out to them again, with this additional evidence of a clear bug, in another attempt to get a proper solution (software fix) to this issue, as it clearly still affects users so many iOS releases later. If nothing comes to fruition from that I might need to consider jailbreaking my device and fixing the root issue that Apple seems unwilling to take responsibility for.

Same issue here !

2 days ago, my iPhone 6 - 128GB running iOS 10.2.1, the latest at the time of writing - went full and started acting weird.

One of the issues is my inability to setup data connection for individual apps.

I did everything from reset network settings to reset all settings passing by multiple soft and hard reboot but nothing changed.

I just do not want to restore my iPhone because it would last several hours because of my 8GB, 32 thousands photos 700 videos and around 350 apps - which holds around 30GB of data.

Thanks for your help

I have looked for a while now on what to do but I have finally figured out the problem sometimes after updates or major resets mine does the same thing but what you have to do is you have to go to the cellular data page in your setting the click on "manage version account" then it will ask you to add your device to your cellular plan then you are all set

I know this thread was posted a while back but I may have a solution that could work for now.

A couple days ago I went to visit a friend and he showed me how to get ios 11 beta from beta.Apple.com and I thought it would be cool so I said alright.

The next day, (still didn't update) my family Almost reached the limit in our plan because we are on a family plan so I started turning cellular data off for apps but after I did that the update was installed so I updated with cellular off.

I have honestly tried everything there is to it did not miss anything and nothing worked.

But yesterday I was tossing around with siri and used 8 ball pool as an example and I did this

1. Go to siri

2. Ask siri : Siri, turn cellular data on for 8 ball pool

3. A switch appears and I turned it off then on

4. Then if you have the app on close it then reopen it

4b. If you don't have the app open you can just open it

5.enjoy what you got cellular data for

NOTE: I am not sure if this does work for all ios but it is worth a shot because I did this on ios 11 but I don't know how all the software has changed so if you've tried everything you might as well go ahead and try this

If you have any questions or comments please send me a message via.*****@gmail.com or reply to this comment

Thank you

Did that really work for you - as ariante stated it only seems to provide the cellular data on/off setting for the whole device, not specific apps.

Not sure if you have checked, but the area to turn on/off cellular data for individual apps is in Settings>Cellular. The list should be at the bottom of the page. If it is not showing there, then is Cellular data turned on there?

I don't know that all of mine are, but it could very well be that they do not show up there until you attempt to use them with cellular data. Have you tried accessing an app requiring data when on cellular network that is not listed there?

I have exactly the same problem as you.I only noticed this morning when I wanted to turn on data for one of my apps because I had no wifi signal,two days ago I was able to do this.

If you are now experiencing typing issues, then you have a problem with the iOS or your backup. The last two steps of user troubleshooting are restore from backup and restore as new. If you restore from backup and it continues the problem, then restore as new. If it works then, you can try loading the backup. But if that does reload the problem, then you will need to restore the device as new again and delete that backup. After the restore, you can sync back all of your content, just make sure you have synced everything before you restore.

sorry to jump in but have you reset all the settings

settings>generial>reset>reset all settings?
