The “Surround Recording” is the feature of TheOneSpy (TOS) that allows you to listen to the sounds taking place in the surroundings of a subject that is being spied via the target mobile device. This feature can be leveraged in two different ways (two sub-features). One way is by “Mic Bug” and the other is “Spy Call.” The “Mic Bug” allow you (the person who is spying) to send a command with the click of a button to the target mobile device through the Internet to record the surrounding sounds of the subject. The “Spy Call” is a sub-feature of the “Surround Recording” feature of TheOneSpy that is advantageous when the Internet is absent. You can listen live to the surroundings of a mobile phone by making a phone call after registering the SIM number of the mobile calling device in TheOneSpy monitoring online portal or the monitoring app. The “Spy Call” sub-feature works over the mobile telephone network and does not need the Internet where the “Mic Bug” requires an Internet connection.
