Does do not disturb while driving use data while in use? I keep on blowing through data when not on Wi-Fi, and that is only when I am driving.

Thanks for the reply, but with the new feature where is senses you driving a car, since it must be using the GPS to sense movement then it must be using the data right? I turned off all the cellular data for all the apps on my phone and in the hour drive home from the office my phone used 0.1 GB of data. No other apps were open and physically turned all the other apps data use off.

Just by unchecking all the apps in the list.
