Mandatory SIM card registration can be described as the process of recording mobile phones with their personal details for active prepaid SIM cards (Jentzsch, 2012). Personal data such as name, physical address and contact details are recorded and stored on a database. In some cases, biometric data i.e. photograph and finger prints are also recorded (Donavan & Martin, 2012). Identification of the mobile phone users is crucial in the SIM registration process.
