Whenever you use your mobile phone, you probably are not thinking that someone in a remote location is eavesdropping on your conversation. Cell phones, however, can be used to track your location and listen to calls you want to keep private. Most people do not need to worry about a bugged, or tapped, cell phone, but those whose occupation involves handling sensitive information may want to consider the possibility. Several telltale signs allow you to know if your mobile phone has been bugged.
Listen for static that comes from your mobile phone. Occasional or constant static may mean that your phone has been tapped. You may also hear static when placing your phone next to another electronic device, like a television or radio.
Look for a sudden drop in battery power. If your phone was recently charged and has full battery power, but its power quickly drains, a bug may be causing the problem.
Look at your phone's Bluetooth settings. An unknown name in the Connections list indicates that someone has connected to your phone and has access to the data stored there.
Watch the phone's screen. If it flashes randomly and briefly, a bug may be installed.
Check your text messages. If the phone has a bug, you may receive strange text messages filled with symbols or random letters and numbers.
Log on to your cell phone account online to see your data usage. If you don't often use data services like Internet browsing or sending e-mail, but you see unexplainable spikes in data usage, this can indicate a bug.
Remove the cell phone's battery if you think it's tapped.
