How does it work: It's simple. Your surveillance operation will be underway in 4 simple steps: 1. Insert a mobile phone SIM card in the device (E.G. free PAYG SIM card from O2 etc) 2 .Conceal the device where it cant be seen... 3. Dial the pay as you go number from your phone..... 4 .Listen - now you can hear what they are really talking about... Power on: open the back cover, put the SIM card into the seats, then it is automatically power on. When booting, indicator will light for 10 seconds, after the indicator is off, cover the back cover then it can be used. Environmental monitoring: starting up normally, dial alarm number, it will be easy to hear the situation within 10 miters around the machine after waiting for five seconds. Sound control dialing: use mobile phones or fixed-line to get through SIM card number in the alarm, hang up the machine when hearing the sound of the machine about 3 seconds, and that means it sets up successfully.

And the indicator will flash. Note: 1.This product does not rely on GPRS positioning, rely on the GSM/GPRS baseband station location. 2.As to the review of my customers,this Mini A8 Tracker could not be used in El Salvador/Slovakia/Spain/UK/Sri Lanka,due to the GPRS Network.
