Q: How do you manually turn on cellular data for apps using the new IOS?

I have the new iPhone 6s and when I am not in a WIFI network I can not access any of my apps. I can only using texting and calls. I try to manually go in and change which apps are allowed to use cellular data and when I turn them all on, the phone goes and changes them all back to off.

iPhone 6s, iOS 9.0.1

    Go to Settings > General > Restrictions > Cellular Data Use > and make sure Allow Changes is activated.

    Allow changes is activated. Once I change an app to "on" I go right back into settings and its flipped back to off. I have tried reseting all statistics, I have deleted all apps and reinstalled. My apps will not set to "on" for cellular data besides "phone"

    Your settings seem to be ok. I would first try a forced restart. Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears. Ignore the "Slide to power off" text if it comes up. You will not lose anything.


    If that does not take care of it you could have a defective device or a corrupted system/app. Try doing a full Restore per the instructions below. If does not work, then your may have a defective device and would need to take it to an Apple Store or Authorized Dealer for evaluation. Hopefully the Restore will fix it.

     

    Please follow the instructions in the article below. The process is rather straight forward as iTunes will guide you along the way. You will have to disable Find my iPhone/iPad first. Don't forget to set it back to On when you are through and also set Send Last Location to ON.

     

    Connect your device to your computer. Then import all your photos from the device to the computer and copy all important documents directly to your computer as well. Then do a full backup to iTunes, just follow the instructions below. Then select Restore iPhone/iPad and iTunes will install a fresh copy of the current iOS and will erase all your data and settings. After iTunes has installed a fresh copy of the iOS, it will ask you if you want to set your device as New or restore from Backup. Choose From Backup. Restoring from backup will bring back all your Settings, Apps, Photos on Camera Roll, etc. You should not lose anything.

     

    After completion check to see if works. There is a possibility that restoring from the backup may bring back some system/app corruption. If this occurs (unlikely) you would have to start over again, set it up as New and install all Apps manually (a time consuming process). You would also lose your photos and documents so it is important to back them up first as I mentioned above. I have done this procedure many times in the past and restored from backup with no difficulties - it takes 30-50 minutes.
