ICCID, IMSI and sim serial number explained? ›

ICCID is the number that identifies the SIM card. IMSI uniquely identifies all Global System for Mobile Communications Association (GSMA) mobile phone subscribers. IMEI is a unique number that signifies the type of mobile device or hardware.

What Is the Difference between IMSI, ICCID and IMEI Numbers? An IMSI identifies the user in the GSM and is a portion of the SIM profile, but it doesn't identify the SIM card itself. The Integrated Circuit Card ID (ICCID number) identifies the actual SIM card itself and not necessarily the user.

Finding and Decoding the ICCID Number

The SIM card ICCID code is typically made up of 18 to 22 visible characters and follows this format: MMCC-IINN-NNNN-NNNN-NN C(X). This code consists of groupings that represent various identifiers and codes, which makes each SIM card unique.

What do ICCID numbers stand for? The format for ICCID Number is MMCC IINN NNNN NNNN NN C x. MM – most SIM Cards have the same first two digits – 89. CC – county code, or MCC (Mobile County Code), used to identify a mobile subscriber's county of origin.

Go to your Android phone's settings menu, then select 'About phone' or 'About device'.

The international mobile subscriber identity (IMSI; /ˈɪmziː/) is a number that uniquely identifies every user of a cellular network.

For Android Phones: Open the Mobile Settings App. Click on Network and Internet and Tap on Cellular Networks. From available networks you can know the SIM card company.

The ICCID is a globally unique serial number—a one-of-a-kind signature that identifies the SIM card itself.

Data that SIM cards contain include user identity, location and phone number, network authorization data, personal security keys, contact lists and stored text messages. SIM cards allow a mobile user to use this data and the features that come with them.

What is Iccid operator code? ›

The ICCID number on a SIM card is as important as the IMEI number for a mobile device. ICCID is stored under the SIM card's memory and helps mobile network operators determine the network to connect. Without ICCID, a mobile network provider can't identify and register a subscriber to the right network.

The IMEI (International Mobile Station Equipment Identity) is an international "Serial number" for your phone (device itself) to properly identify it on the carriers network. ICCID (Integrated Circuit Card Identifier) identifies each SIM internationally.

Your ICCID number is between the first two digits (89) and the last digit. It's a 16-digit number beginning with 64. This is your Spark SIM card number.

A PUK, sometimes known as a network unlocking code (NUC) or personal unlocking code (PUC), is a unique sequence of eight digits that your network must supply, as long as you fulfil certain criteria. A PUK is required when you want to unlock a phone.

The ICCID is a globally unique serial number—a one-of-a-kind signature that identifies the SIM card itself. It stands for Integrated Circuit Card ID, a 19- or 20-digit number that's typically printed on the back of a SIM card. The ICCID isn't the only identification number visible on most SIM cards.

The International Mobile Subscriber Identity (IMSI) is another unique identification number assigned to a specific SIM card. Unlike the MSISDN, IMSI is not directly associated with a phone number.

IMSIs are used in any network that connects with another and are stored on the SIM card. Traditional SIMs contain a single IMSI, provided by the selected network operator. The IMSI is installed onto the SIM during manufacture and ties the SIM to the operator's network (the home network).
