Why is a data connection required?
Since waze is using live map data, it requires an active data connection to keep you informed at all times about the ever-changing situation of the road. All map, traffic and other event data is saved on our servers and sent to you based on your location and proximity to those events. The active data ensures that you will always receive the most updated map, as well as traffic events, wherever you are driving. Once you view a map of a certain area, this map is cached and saves on your phone so you won’t need to download it again the next time you are driving in the same area.
