ICCID (Integrated Circuit Card Identifier)

An ICCID (Integrated Circuit Card Identifier) is a unique number assigned to a SIM card used in mobile devices. It functions like a digital serial number, identifying your specific SIM card globally. The ICCID helps mobile networks recognize and authenticate your device when connecting to their service. It’s typically 20-22 characters long and includes information about the country, network provider, and the individual SIM. This identifier is important for managing service plans, transferring numbers, or troubleshooting. Think of it as the SIM card’s fingerprint—unique to each card and essential for secure and proper network operation.
