You can find the ICCID number for your eSIM in your device's settings. On an iPhone, go to Settings > General > About and scroll down until you see "ICCID"; on Android, navigate to Settings > Network & Internet > Mobile Network (or SIM Status) and look for the ICCID field.
What is an ICCID Number?
An ICCID (Integrated Circuit Card Identifier) number is a unique identifier assigned to a SIM card. This 19- or 20-digit number is crucial for identifying the SIM card globally. The ICCID number plays a significant role in various functions, such as SIM tracking, device management, and troubleshooting. In the realm of cellular IoT, the ICCID number is indispensable for managing and organizing large-scale deployments. Essentially, the ICCID integrated circuit card number ensures that each SIM card is uniquely identifiable, facilitating seamless operations across mobile networks.
Structure of an ICCID Number
The structure of an ICCID number is meticulously defined by the International Telecommunication Union (ITU). An ICCID number typically follows the format MMCC IINN NNNN NNNN NN C x. The first two digits (MM) are always 89, signifying the telecommunications industry. The subsequent two digits (CC) represent the country code, followed by the Issuer Identifier Number (IIN), Individual Account Identification Number (IAIN), and a Checksum (C). This structured format ensures that each ICCID number is globally unique, making it an essential component in the identification and management of SIM cards.
Importance of ICCID Numbers
ICCID numbers are pivotal in ensuring the efficient, secure, and accurate management of mobile services. These numbers are integral to network registration, security, user management, device activation, and roaming services. For mobile network operators, ICCID numbers are invaluable for managing subscribers and tracking usage. They also enhance security by preventing unauthorized access to the network. In the context of IoT, ICCID numbers are used to identify devices and facilitate over-the-air updates and information retrieval on SIMs. Thus, ICCID numbers are a cornerstone in the seamless operation of mobile networks.
How to Find the ICCID Number
Locating the ICCID number can be done through several methods:
Printed on the SIM card or packaging: Often, the ICCID number is printed directly on the SIM card or its packaging.
Using AT commands for IoT devices: For IoT devices, the ICCID number can be retrieved using AT commands.
Onomondo Platform and API: The Onomondo Platform and API provide tools to retrieve the ICCID number.
Soracom Platform and API: Similarly, the Soracom Platform and API offer methods to find the ICCID number.
It’s important to remember that the ICCID number is a unique identifier that distinguishes each SIM card globally, making it a critical element in mobile network management.
ICCID vs. IMSI vs. IMEI
In the world of mobile networks, ICCID, IMSI, and IMEI are three distinct identifiers, each serving a unique purpose:
ICCID (Integrated Circuit Card Identifier): This number uniquely identifies a SIM card. It is essential for SIM tracking, device management, and troubleshooting.
IMSI (International Mobile Subscriber Identity): This unique code is used to identify and authenticate subscribers on mobile networks. It plays a crucial role in user management and network registration.
IMEI (International Mobile Equipment Identity): This 15-digit identifier is used to identify mobile devices, such as phones and modems. It is vital for device tracking and management.
Understanding the differences between these identifiers—ICCID, IMSI, and IMEI—is crucial for effective IoT management and the seamless operation of mobile networks. Each identifier serves a specific function, ensuring that SIM cards, subscribers, and devices are accurately identified and managed within cellular networks.
