Listening devices nowadays have become so sophisticated, small and powerful that a GSM prepaid SIM card is all that is needed to text alerted to movement & listen in from any mobile phone worldwide. GSM listening devices are battery or AC powered, smaller than a matchbox, particularly high quality inbuilt microphone that can pick up conversation up to 10m away quite easily and are 100% silent. It will never ring and no one will know if anyone is listening in. Simply call the prepaid SIM number and you have an instant connection to the bug or listening device.
