General

CRT19D+, gps tracker that also behaves like a global cellphone because it features two way calling, sms alerts, and supports the four global standard GSM frequencies so you can trust it to work anywhere in the world!

Better Than Your Average GPS Tracker: This amazing GPS tracker does everything those other trackers do like (1) send you its GPS location via SMS, either on demand or at regular intervals, (2) help you keep track of people, vehicles, or other assets, and (3) send you an alert when the GPS tracker leaves a predefined area, BUT it does the job better than the rest with an improved GPS receiver that offers more accurate GPS readings, advanced functions like remote monitoring where you can send a text message to the tracker to turn on its MIC and transmit all the nearby sounds to you (eavesdropping). Most importantly, this incredible tracker also picks up GPS signals in locations where other trackers don't!

How Does It Work?: GPS trackers basically all work this way. You insert an active SIM card in it, then put the tracker in the trunk of someone's car for example. As your mark is driving around, you can send the tracker text message instructions such as a request for current location. The GPS tracker will then send you a text message with its current longitude and latitude. The G248 goes one better...

It Behaves Like A Quadband Cellphone: Since GPS trackers use SIM cards as the means by which they communicate with their owners, it was just a matter of time before someone came up with the thought, "wouldn"t it be great it we included a MIC and speakers on the tracker, so people could use the tracker as an emergency cellphone too?" A perfect example of how this may come in handy is: You've decided to spend your vacation exploring the great outdoors. After several days, you've become lost and your supplies are dwindling. Using your GPS tracker you call your friends for help. At the same time, your friends send text instructions to your GPS tracker which gives them your exact location.
