GSM listening device ambient sound conversations listen through low-end mobile phone

Only 5 units at this price... Tiny listening device, can be placed anywhere, it's an N9 replic (as mentioned in the title). Listen to conversations around the device, even if you are 1 or 1000km away. When the listening device detects sound above 50 to 60db, it calls you. I deliver in person at Castelo da Maia or send by cash on delivery via CTT for €7.95. Product price and shipping fees are non-negotiable. How this listening device works: 1-) You must acquire a SIM card from any carrier, with the tariff plan you prefer. 2-) Remove the PIN code from the mobile card or SIM card; to do this, simply insert the card you wish to remove the PIN code from into a mobile phone, then go to SETTINGS, then SECURITY, and there you will find an option similar to "Remove PIN code" or "disable security code", etc. 3-) If the card is new, make a call with it so that the call is answered on the other end; if you do this and everything goes well, the card becomes active. 4-) Now insert the card into the listening device until a red light turns on; when this light goes off, wait 5 or 10 seconds, and you can then call the number of the card inside the listening device. 5-) This listening device has the function that when it detects sound above 50 to 60 db, it calls the mobile number that previously called it (fixed function).
