GT08D 4G OBD In-Vehicle GPS Tracker

The GT08D is a plug-and-play 4G OBD in-vehicle GPS tracker that uses the SIMCom 7670SA communication module. It supports 4G LTE and 2G networks and integrates GPS, Beidou, and AGPS for assisted positioning. The device is easy to install—no cutting or splicing of wires is required—and provides real-time vehicle location tracking, historical routes, geofencing, vibration alerts, power-off alerts, speeding alerts, and data backfill for dead zones. It is suitable for managing private vehicles, rental vehicles, corporate fleets, taxis, and new energy vehicles.

The GT08D 4G OBD GPS tracker is powered via the vehicle’s OBD port; simply plug it into the corresponding port to begin use, reducing installation time and the risk of wiring issues associated with traditional hardwiring. The device is equipped with a SIMCom 7670SA communication module, supporting the LTE-FDD B1/B2/B3/B4/B5/ B7/B8/B28/B66 bands and is compatible with 850/900/1800/1900 MHz 2G networks. It can be configured according to the target country and local carrier frequency bands.

The device features dual-mode GPS and BeiDou satellite positioning and supports AGPS-assisted positioning, with positioning accuracy within 10 meters. When used with the FOFN vehicle tracking platform or the customer’s own server, it allows users to view real-time locations, historical tracks, vehicle status, and alert information. A built-in storage chip saves vehicle operation data when network signals are weak and automatically uploads the data once connectivity is restored, minimizing the loss of track data.

The GT08D supports features such as geofencing, vibration alerts, power-off alerts, speeding alerts, and low-power sleep mode, making it suitable for location management of insured vehicles, corporate fleets, car dealerships, rental vehicles, taxis, passenger vehicles, and personal vehicles. The device supports TCP/IP communication, can connect to servers via a domain name or IP address, and supports communication protocol integration as well as OEM/ODM customization.
