Overview:This mini GSM/GPRS/GPS tracker is designed to help track the old, kids, pets, valuable items or monitor the surroundings conveniently. All you need to do is to insert a SIM card and send some short commands from your smartphone. You’ll be able to get accurate locations of the tracker and hear the sounds within 10 meters/98 feet of the tracker, plus you’ll get alerted once the sound reaches 45dB when the tracker automatically calls the number you’ve authorized as you like.
