JSIII, it is always good to clarify what uses data, so I'd be happy to specify. Unless you are live streaming on a third party app, simply recording on your video camera will not use any data. You can see here what uses data (go to step #2): http://spr.ly/6607Ee9i9
To better understand your needs, what has indicated that your data will be used while recording? What model phone are you using and what do you plan on doing with the videos?
