SIM508 module is a Tri-Band/Quad-Band* GSM/GPRS-enabled module that is also equipped with GPS technology for satellite navigation. The compact design of the new SIM508 makes it easy to integrate GSM/GPRS & GPS as an all-in-one solution. You will save significantly both time and cost for the integration of additional hardware components.

The combination of both technologies allows goods, vehicles and people to be tracked seamlessly at any location and anytime.
