How do you disable cellular data use for all apps except for one? Is there any way to disable all the background applications except WhatsApp for cellular connections? I have WhatsApp plan only from my carrier, I want to only use WhatsApp when I turn on the cellular connection.
I dont see WhatsApp / Facebook or main apps in cellular section "Use cellular data for" but only default apple apps.

How to disable for cellular only?
In the Settings menu, once you've scrolled past Twitter/Facebook/Flickr/Vimeo, you can see all of your installed apps. Tap any app, and you can uncheck Background App Refresh and Cellular Data individually.  Do that for every app except WhatsApp, and you should be set!
