We’ve done some analysis, and the current application averages usage of 12MB of data for a 24-hour shipment. To put that in context, with a $40 AT&T prepaid plan, you could run 177 shipments, at a cost of $0.23 per shipment. This is roughly the equivalent of streaming audio on Pandora or Spotify for 15 minutes or browsing Facebook for 30-45 minutes. Optional navigation features can incur slightly higher data charges (similar to using any map/navigation apps), but these features are not essential to delivery.
