GSM Phone

avl in hand Overview
GT300 is a powerful GPS phone for personal tracking. With superior receiving sensitivity,
fast TTFF and Quad-Band GSM frequencies 850/900/1800/1900, its location can be
monitored in real time or periodically reported by a backend server or other device.
Based on the embedded @Track protocol the GT300 can communicate with the backend server
through the GPRS/GSM network to transfer reports of Emergency/SOS, Geo-fence boundary
crossings, Low Battery or scheduled GPS position among other advanced features. Users can
easily dial a preset phone number by using one of the four quick dial buttons or the SOS
button. System Integrators can easily communicate with the GT300 using the @Track
protocol.
