VL103M is a compact, durable, and versatile 4G GPS tracking device, ideal for tracking and securing vehicles, motorcycles, and light commercial vehicles. The device features an IP66 dustproof and waterproof enclosure and supports a wide voltage range (9–90V), making it suitable for a wide variety of vehicles.

Key features:

4G LTE connectivity – operates on Cat 1 LTE networks, ensuring fast and stable data transmission, with fallback to 2G GSM networks if needed.
Accurate positioning – supports GPS, GLONASS, BDS, GALILEO, and AGPS systems, location accuracy <2.5 m.
IP66 dustproof and waterproof – operates reliably even in harsh weather conditions.
Wide power voltage range – suitable for 9–90V DC systems, allowing installation on cars, motorcycles, and smaller commercial vehicles.
Small and discreet – dimensions only 92 x 32 x 18.5 mm, weight 54.6 g.
Driving behavior analysis – detects harsh acceleration, braking, cornering, and collisions.
Geofencing – notifications when the device enters or leaves a designated area.
Vibration and motion sensor – notifications upon vehicle movement or vibration.
Battery protection – automatic battery protection if the vehicle's battery voltage drops too low.
Bluetooth 5.0 – allows the use of various accessories and convenient device configuration.

SIM card usage:

VL103M works with nano-SIM cards from all mobile operators. The SIM card must be purchased separately (either contract or prepaid). The device’s monthly data usage is very low – usually up to 100 MB per month is sufficient.
