To use the bug all you have to do is insert any SIM card into the concealed holder then dial in and the device will automatically answer your call and allow you to listen to the surrounding conversation in perfect clarity, if you wish to use the voice activation/shock sensor function all you are required to do is send an SMS command to the device giving it your number on detecting sound or vibration the device will call your number.This function can be switched on and off remotely. Just place the device anywhere suitable e.g. a desk, table,in a car, worktop etc. It doesn’t even have to be hidden, with no lights or sound it just appears to be a standard memory stick . If the device is left plugged into a PC/Laptop, it will be able to remain permanently on, as it will draw power from the PC/Laptop rather than the battery making it useful for monitoring in a office especially if left pluged into the rear USB port on a PC.
