Sim Card Decoder

How Our Sim Card Decoder Works

Our Sim Card Decoder tool analyzes ICCID and IMSI numbers to provide detailed insights about your SIM card. The ICCID (Integrated Circuit Card Identifier) is a 19-20 digit number unique to your SIM card, while the IMSI (International Mobile Subscriber Identity) is a 14-15 digit number identifying the subscriber. Enter your ICCID and/or IMSI to see details like the operator (e.g., Vodafone UK), country, and validation status.

What is an ICCID?

An ICCID is a unique identifier for SIM cards, used in telecom and IoT applications. It includes the Major Industry Identifier (MII), country code, issuer identifier, account ID, and a checksum validated by the Luhn algorithm.

What is an IMSI?

An IMSI identifies a subscriber on a mobile network, consisting of a Mobile Country Code (MCC), Mobile Network Code (MNC), and Mobile Subscriber Identification Number (MSIN). It helps route calls and data.
