What is the effective range of the GPS Smart Pendant? Does it work from everywhere, or just within a few blocks from the home like other pendants?

Many emergency pendants available today are a lot like a cordless phone with a panic button – they use the land-line to make a call to emergency services, so they won’t work if you’re too far away from the home. The GPS Smart Pendant, however, is more like a combination cell phone/speaker phone/GPS device, in that it can make a phone call from anywhere there is cellular coverage, and it transmits coordinates every few minutes. The GPS Smart Pendant also has a fall detection feature. The GPS pendant uses the AT&T cellular network so it has tremendous coverage and works nationwide wherever cellular coverage is available.
