Mobile phone cloning is a technique where the data from one cell phone is transferred into another phone. The other cell phone becomes the exact replicate copy of the original mobile phone like a clone. Phone cloning is illegal in most countries.
Hacking a phone can be done with an app. Once one of these apps are activated on your phone they can track just about all your activity. These applications can even remove the necessity to clone a phone. On the other hand, a cloned phone requires copying the SIM card and the IMEI number to do so.
Phone cloning involves copying the identity of one mobile device for use on another. Although there are three main cloning methods, AMPS, CDMA, and GSM cloning, only the latter is more popular.
