答案 Spy Cell Phones A spy phone is a mobile phone or a spy device that allows a user to monitor and hear or record conversations and other activities taking place over the phone. Spy phones can function in different ways. They can be used as listening devices whereby secretive conversations can be tracked. They are popularly used by secret agencies to track criminal activities that are carried out over networks. They can be used for tracking periodic calls and recording the frequency of calls from certain suspicious numbers. Also, they can be used for monitoring business and household activities while the cell phone user is away. Although spy cell phones have many positive sides, they give rise to legal as well as moral concerns, because spy cell phone software is easily available. Cell phones are easily transferable to spy phones. Their ready availability makes them subject to illegal use.
