A device, typically a mobile phone, acquired specifically for illicit activities or to maintain a level of anonymity. These devices are frequently prepaid and purchased without requiring identification, allowing the user to circumvent tracking by law enforcement or other entities. For example, an individual engaged in illegal sales might use such a device to coordinate transactions, keeping it separate from their primary means of communication.
The appeal lies in the perceived security and disposable nature. By using a separate device, individuals seek to insulate their personal communications and identities from scrutiny. Historically, this practice gained traction with the rise of mobile technology and the increasing accessibility of inexpensive mobile phones. The benefit is the creation of a barrier between legitimate and illegitimate activities, albeit one that is not foolproof.
