How the Magnetic GPS Tracker Works
The ST-905 uses GPS satellites to determine its location and a GSM SIM card to send tracking data. After inserting a compatible SIM card and configuring the tracker, you can view location information through the SinoTrack app or web platform. SMS-based location requests may also be available, depending on the device setup and SIM service.
The built-in magnet allows the tracker to attach to a suitable magnetic metal surface. Before use, check that the surface is magnetic and that the tracker is firmly secured. For best GPS reception, choose a position that is not fully enclosed by metal. The tracker does not need to be wired into the vehicle, but it must be recharged when its battery becomes low.
Call and Voice Monitor Functions
You can call the SIM card number installed in the SinoTrack ST-905 to request its location. The tracker responds with a Google Maps location link, subject to SIM service and correct device setup. This call-to-locate feature is separate from voice monitoring.
The ST-905 also supports a Voice Monitor call-back function. After an authorised control number is configured, sending SMS command 66 from that number makes the tracker call it back. This function requires an active SIM with call service. Use audio monitoring only with appropriate consent and in accordance with applicable privacy requirements.
