New technology. Just a call, this device allow you to spy the voice
anyone in any place.
You only need to buy a new SIM card, place it in this device. Once you
call this number, this device will auto answer,  and it is working
like a phone with auto answer without speaker. So you can actually
hear anyone's talking about you or whatever when you call in that sim

this device look like a USB hub or small USB device. But actually it
is a spy tool. If you store this beside a computer and put in to a usb
