How the SinoTrack ST-904 Works
The ST-904 uses GPS satellites to determine its location and a compatible GSM SIM card to send location information. Users can access tracking features through the supported SinoTrack mobile app or web platform. A SIM card with suitable service is required and is not included unless stated in the product package.
The tracker offers different working modes. Continuous tracking provides more frequent location updates and uses battery power more quickly. Movement and standby modes reduce activity while the device is not moving, which can extend the time between charges. Actual battery life depends on signal strength, tracking frequency, network service and selected mode.
