Our devices support 2G/3G/4G LTE-M across 142 countries so the tracker keeps working everywhere you go, including regions where older cellular tech persists.

Five-layer security system

Infrared beams, door sensors, accelerometer theft detection, 125dB siren, and LED strobes all working in concert.
