T4Carrier enables location sharing and other communication with your trusted partners during active load assignments only and always over a secure connection.
Continued use of GPS running in the background can dramatically decrease battery life. However, T4Carrier doesn't run the GPS services in the background continuously. The app uses GPS only when the device moves significantly.
