The M33 features a new 3G 4G module which allows the 3G 4G GPS tracker to receive and transmit data in the 3G 4G and GPRS network areas. This means it has a distinctive edge over those tracking units which relied solely on a GPRS network. GPS trackers that can only operate with a GPRS network (2G - 2.5G) would stop live tracking and turn into data loggers. This new 3G 4G GPS tracker can now track and send live data from a 3G 4G and GPRS network areas.
This portable GPS tracker features a large and visible SOS button that, when pressed triggers the GPS SOS alarm. The button is protected and grooved to avoid accidental pressing of the GPS security alarm button. Once the alarm is pressed, a 24/7 security monitoring centre is alarmed and depending on the situation, will inform authorities like police, ambulance or a security guard. Calls to 000 usually require identification and verification (who is calling, what is your location, nearest crossroad, etc)as these services get inundated with calls or often receive prank calls. Also, 'triple O service' (OOO) can only be contacted by phone. Some critical situations do not allow for a phone call.
This GPS Tracker solution is an excellent way to be able to have a two-way communication with the vehicle driver. You can send text messages directly to the navigation GARMIN device via GPRS (note: free communication and no cost for SMS text messaging) and your driver can reply to the instructions/messages.
