Q: IOS9 upgrade mobile data toggle not working

I've spent 4+ hours today back and forth between Apple and Verizon doing everything including restoring my phone but the problem is STILL there!  The ONLY thing that we didn't do was go back before IOS 9. Apple......are YOU listening?????

For those who are considering the full reset, I tried it and it only partially fixed the problem. In the "just like new" state all of the apps had their cellular data turned on, but if I turned one off it would remain off and I was not able to turn it on again. I didn't want to completely set up my iPad again, so I restored from backup and the problem remains exactly as Charlenii13 describes it.

I have AppleCare so had a chat with Apple support. Tried everything the tech told me to try but nothing worked. She said she will follow up on the problem and call me tomorrow.

Same issue as everyone else. Restored my phone and it did nothing. Anything that I had turned off data wise on ios8 will not come on for iOS 9. Fortunately, second party maps apps work because this has affected my maps, as well as App Store and iTunes  store. Did everything tech support suggested. Suppose we need to wait for iOS 9.1 or whatever. I'm irritated. I have a 6+

Settings > Cellular > Cellular Data Network

same problem here on iPhone 5. the iPhone 6 is okay, but the 5 is busted even after a restore.  help!

Hi, Same problem with me. I've seen this problem is ios 9 beta versions but thought it will be resolved in ios 9 full release but it's a shame that apple did not test this.

Mine is Iphone 5s 16GB

Mobile data is an important feature and should work. My Whatsapp is not working on Mobile data.

-A clean restore also can't help!

-Apps like Google Maps,Whatsapp, Safari not working at all with Mobile data.(2G or 3G)

-Toggle switches off automatically though you turn it on.

Something has suggested putting WAP in username and password of Mobile network options which did not work either.

APPLE PLEASE FIX THIS ASAP

Does anyone knows Twitter account for Apple?

Settings ---> Cellular ---> all I have in here is wether to turn off cellular data, enable LTE, Data Roaming etc. I don't see a spot that shows Cellular Data Network.....

I concur. I performed a clean reset as well. It doesn't seem like anything can be done from user land.

Quote from Ross1805 : "HI all, I hope this may help, my wife has had the same problem, no mobile data. We looked up getting mobile data setting resent from network provider, but this still didn't fix, until I saw in the settings under username and password were blank.  found out to put WAP in both, light the fireworks, it worked."

It doesn't sound like your issue is the same issue we all are experiencing in this discussion. Go to Settings > Cellular > Use Cellular Data For: (scroll down). When an app is toggled on, it will not stay on.

I sent a tweet to @Tim_cook.....I'm sure it won't help. I do t think Apple has a Twitter account

Problem: Go to Settings > Cellular > Use Cellular Data For: (scroll down). When an app is toggled on, it will not stay on. I have tried turn off/on, hard-reset (hold home + sleep button), reset all settings, reset network settings, restore iPhone from previous backup, and also restore iPhone to new and then restore from previous backup. It didn't work.

However, prior to restoring from backup after resetting the iPhone as new, it DID work. I could toggle cellular on/off for all apps. It apparently something to do with the previous backup. If you are willing to restore the iPhone as new and then manually download everything fresh vs. restoring the previous backup, it might work, but as previously mentioned, this is the hard way. There has to be a way to fix this--Apple?

So, cprestonw, when you reset the iPhone as new you were able to turn the cellular data on for an app, then off, then on again and it stayed on? I'm just wondering because when I did the clean reset I found that all the toggles were green, but once I toggled one to off it stayed off and I was not able to turn it on again. Just curious.

I Have filed the bug to apple through the bug reporter and made the importance High and a serious Bug, The best i can do,

To Summarise

Resetting the Settings - Does Not WOrk

Restoring from Backup - Does Not Work

Completely Wiping - Partially working, not a permanent Fix and also not an option for many

Many Thanks

How nice for APPLE that the new NEWS app works on cellular but nothing I WANT to work does.

Shame on you APPLE for being so negligent.
