Description : 

Two way GSM audio spy device calls you from anywhere in the world when it detects sounds around its vicinity. 

Simply insert a GSM SIM card and program it to your desired phone number for call back and start doing your spy business from anywhere in the world! 

Just insert a SIM card into the audio spy device, send a text message containing the activation letters as stated in the products user manual (e.g. XXX followed by your cellphone number from your mobile phone, then your bug is active and ready for action!) 
  
This two-way audio spy device comes with a manual switch located next to the SIM card slot. 

Switching to option (A) only allows you to call the spy audio device and listen in to conversations that are being detected. 

Option (B) allows the spy audio device to call you when it detects sounds, or if people are talking, while still allowing you the freedom to call the device and listen in to who's talking. This feature makes it much more advanced than other GSM audio bugs on the market today.
