We would not recommend it! Cellphones can be turned on and off at will - whereas GPS tracking for cars cannot easily be turn off. A cellphone will burn through battery fast if the GPS chipset is left on and working all the time. Cellphones are not as accurate as dedicated gps car tracking hardware devices.
The GoTrack 3-Wire GPS tracking device for cars is perfect for vehicles made before 1996 and large trucks and buses, and discreet installation. We promise an easy do-it-yourself installation, no software needed, no long term contracts, and a variety of data plans to choose from.
