Ios 9 cant enable mobile data for application(s)?

I Just upgraded to the new iPhone 6s. If you back up from iCloud problem still exist with apps. I recommend deleting apps and download them again after backup is complete

same issue after ios9 update on iphone6. i had few apps switched off for cell data and now it's locked in that position permanantly. i deleted/re-downloaded the app but didn't solve the problem. also tried 'reset network settings' and 'reset all settings' but didn't work. there seems to be major issue every time i update to newer ios, and i have to spend many hours trying to restore my devices to where it was...or my ipad2 never recovered. i'm switching back to android when my contract is up.

Reporting the same isue from Spain

plz replay here if any one fixed the problem 😟

Reply to: " I was stuck with the same issue in a critical situation where I need to use an app but was unable to turn on cellular data to that app. But I fixed it by erasing my iPhone and restoring the backup...(using) the file I backed up before updating to iOS 9 from 8.4" -

Really great advice for those who have backups dating prior to iOS 9.

Apple didn't allow me to backup my iPhone and iPad, on 8.4., because I didn't have enough storage in iCloud. I would have had to pay Apple $4.99 per month, which seemed like a silly added monthly expense, for iCloud storage to include the 50 gb's worth of data on my iPad. Who knew something like this would happen, and that we would all need backups to protect our devices from Apple updates? My iPad never leaves home, and has a protective cover - I wasn't worried about its contents being lost. NOW I've bought a higher storage plan, and it also costs less than before, but Backup is broken in iOS 9, so the bigger storage plan is not only too late but useless.

In hindsight, their wanting me to pay $4.99 per month (the price then) just to backup my two devices seems like extortion, if the importance of that backup was to guarantee protection from their own updates.

Reading about people who in emergency situations can't turn on cab summoning apps because the cab app's toggle is stuck in the "off" position - wow. Bad news. So sorry!

"Who knew something like this would happen, and that we would all need backups to protect our devices from Apple updates?"

Every developer known to man, that's why they all recommend you take backups. You should always have a semi current backup in case something happens, that is just best practice for everyone living in the digital age. If you have a computer you can back up your iPhone/iPad whatever for free, unlimited! What a concept! 😉

Fix buggy software before it is sent out to users. WOW. What a concept!!!! 🙂😁

Dear all,

My problem just got resolved today. I reset my settings to factory settings and the problem was solved. Only thing to remem when you set up a the iphone set it up as new iphone if u dont have backup before the update like i didnot have. Idid take a backup of all my contacts and photos in my gmail and PC. so no prob in that. Messages will go away but thats the price of updating an ****** ioS update.

I just restored my backup from 6 to 6s and the problem persists on 6s, so it has something to do with your profile/setting @ the time of iOS 9 upgrade. WTH Apple, main reason I switched from Android is that your OS works ... what a horrible experience ...

Same issue here. I actually reported the issue during the final public beta.

downgrading to iOS 8 from a backup only works if you have not backed up since downloading iOS 9.

SSame problem for me too...SORT IT OUT APPLE !!

Yep, same here. I deactivated mobile data for most of my apps since I was abroad, updated to iOS 9 there, and now I can't switch it back on. Very frustrating, my expensive 4G bundle is useless until this solved. Please Apple, fix this soon. Oh, and Apple, to which address can I send my bill of my 4G bundle that I'm not able to use at the moment??

SAME ISSUE FROM TURKEY!!!

i Upgraded büt This problem continues. İ think Apple should fire their business analysts. i cant write easiyl! Keyboard is riddicoulus.

Maybe we should start thinking android!!

Same issue from France !! Even with the new update ios 9.0.1 that was suppose to fix bugs, I still can't use mobile datas for application that weren't "on" when I moved to ios 9 !!

Same issue from indonesia !!
