iPhone using data despite per-app cellular data being disabled My iPhone 5 with iOS 7 is using data for no reason. I have done everything I can think of to stop this.


  Turn off your wifi, then reset your cellular network statistics, let it sit for 5 minutes, then go back to the cellular pane in settings and see whats using the connection

Here are my test results. This seemed like a good idea so I did it. I was extra thorough and did it for 2 hours. During the 2 hours I waited it did not stop at all. 



Here is everything I have turned off. 



Here is my usage. 



I have turned off Background App Refresh. I have also closed all my apps. 

What else can I try?
You need to also turn off background updates, which is where the bulk of the data usage is likely occurring.

Settings> General > Background App Refresh > Background App Refresh Off. Of course, you can choose which apps you wish to turn off individually for background refresh instead.

Don't forget that if you are worried about cell data usage, you can also put your phone in Airplane mode, which turns off all radios, but then manually turn on Wifi. This will force your phone to use only Wifi, as the cell radios are off. Simply turn off Airplane mode when you wish to use the cell radio again.
