The integrated circuit card identifier, frequently abbreviated as ICCID, is a unique serial number that identifies each SIM card internationally. This identifier is essential for network authentication and service provisioning. Locating this number on an Android device can be achieved through several methods, depending on the device’s operating system and manufacturer customizations. These methods generally involve accessing device settings or utilizing specific dialer codes.
Accessing the integrated circuit card identifier is important for a variety of reasons, including troubleshooting network connectivity issues, transferring service to a new device, or verifying SIM card authenticity. Historically, obtaining this number required physical removal of the SIM card. However, modern Android operating systems provide software-based methods that streamline the process, reducing the need for physical access to the card itself. This evolution improves user convenience and reduces the risk of physical damage to the SIM card or device.
