CrashDetech uses data to upload your trips to the cloud. The default setting is to only upload completed trips when connected to Wi-Fi, which means, unless you change this setting you will not incur data charges during each trip.
In case of an emergency, the CrashDetech app requires a data connection in order to alert and share your location with our 24/7 emergency call centre. It is of utmost importance that you have data available and enabled on your device. Please refer to Trip Monitoring Best Practices and Crash Detection Best Practices.
