The identification number associated with a subscriber identity module (SIM) card on an Android device is crucial for various functionalities, including mobile network identification, authentication, and certain service activations. It’s a unique identifier, often referred to as the Integrated Circuit Card Identifier (ICCID). As an example, the ICCID can be used to port a mobile number to a new carrier, register a device on a network, or when contacting a mobile provider for support.
Access to this identifying information offers significant benefits. It enables users to manage their mobile accounts effectively, troubleshoot connectivity issues, and facilitate device management. Historically, accessing this information required direct interaction with the physical SIM card or specialized applications. However, Android operating systems have integrated methods to retrieve this identifier directly from the device’s software.
