What is an ICCID number and why is it important for mobile IoT?

The ICCID is a globally unique serial number — a unique signature that identifies the SIM card itself. It stands for Integrated Circuit Card ID, a 19 or 20 digit number usually printed on the back of the SIM card. The ICCID is not the only identifier shown on most SIM cards. Other identifiers used in cellular networks include IMSI and IMEI along with several other identifiers. In this article, we’ll dive into ICCID and what makes it important, take a closer look at where it came from, what it means, and how things are changing with the advent of the technology. eSIM and eUICCID. to find 20 digit sim card number

What does the ICCID number really mean?

First Two Digits of the ICCID The ICCID of an IOT SIM Card is always 89, a telecommunications industry identifier. This code distinguishes the SIM from other chip cards, including credit cards and certain types of government or business identification.Next is the country code, 2 or 3 digits long, depending on the region. The country code is defined by the International Telephone Union (ITU) and is different from the mobile country code (MCC) used in IMSI.The next set of numbers is the mobile network code (MNC), the 1- to 4-digit identifier of the mobile network that issued the SIM — in other words, its home network. If your device roams in another country, it must connect to the local network and the MNC allows it to identify itself to the new network. In today’s world where there are many partnerships between mobile companies and service providers, you may find that the SIM MNC indicates a partner company, not the company you purchased the SIM from. from that.According to MNC, the rest of the SIM’s ICCID consists of a unique number that distinguishes it from every other SIM hardware on the planet. Finally, there is a single check digit calculated by a Luhn algorithm. You’ll use your device’s ICCID number in most communications with your network provider — to sign in to your dashboard, activate your service line, or connect with customer support.

How do you find an ICCID number?

Usually, the ICCID number can be found on the SIM card or the packaging it came with. Depending on the device type, you can also look up the SIM’s ICCID from within the user interface. For example, on mobile phones it is usually listed in the settings.

The distinction of the ICCID is usually assigned sequentially by your issuing mobile network, your home network, for that SIM. In some cases, the SIM manufacturer that works with your carrier’s network may generate numbers.

ICCID vs IMEI and other types of mobile network identifiers

In addition to the ICCID, which is created to identify the hardware of the SIM, there are several other codes and identifiers associated with the mobile network device. Here’s a quick overview:

IMSI

An international mobile subscriber identifier (IMSI) is used by the mobile network to identify a particular line of service to which your data plan is attached. If you have a SIM card in your device, the modem module will read the IMSI from it. When a device needs to establish a connection, the network identifies it using IMSI. Normally, IMSI has 15 digits: 222-333-444444444

• The first 3 digits (222) of the IMSI are the mobile country code (MCC).
• The next 2-3 digits (333) are the mobile network code (MNC).
• The remaining digits (444444444) identify the service line or what is called the subscriber.

IMEI

A 15-digit number, the International Mobile Equipment Identity (IMEI) is usually printed in the device’s battery component. It is a unique number that identifies the device to the network when it is checked against the global IMEI database. An IMEI is usually broken down this way:

• 22-333333-44444-5
• 22 identify reporting agency
• 333333 is the actual type allocation code (TAC) digit
• 44444 represents the device’s special ID number
• 5 is the check digit

MSISDN

The Mobile Station ISDN number (MSISDN) is the complete telephone number, including the country code, of the part of mobile equipment used to complete voice calls and route SMS messages.

Ki and ADM . keys

These two codes are used by the network to authenticate a device.

• The Ki key is a cryptographic code associated with a subscriber.
• The ADM Key unlocks administrative capabilities — with it, users can make changes to aspects of the software that are normally locked down.

OPc

An operator code (OPc) is assigned to a specific operator and is used to generate keys. It’s a static code that remains the same for all subscribers and SIM hardware under a particular operator.

What is the relationship between ICCID and IMSI?

So, although there is always only one ICCID and often a single IMSI in a SIM card, there are cases where the card carries multiple IMSIs. For example, if a device is on the move and needs to connect to networks in different regions, its SIM card may have several IMSIs onboard and switch them out based on its current location. while, the new world of eSIM and eUICC technology is opening up more possibilities — and confusion — around ICCID and IMSI.

How does embedded SIM technology affect ICCID?

Embedded SIM technology, also known as eSIM, is disrupting the world of mobile networks. Because it’s embedded in the device, eSIM offers a number of advantages over traditional SIM cards – but there’s also quite a bit of confusion surrounding the terminology and its associated factors. Here’s a quick overview:

ESIM (Embedded SIM)

The term eSIM refers to the hardware component of the SIM, usually soldered to the device’s motherboard. It usually holds more non-volatile memory than a standard SIM card and — with the help of eUICC — it can switch between several SIM profiles and network subscriptions. That’s where things get a bit complicated when it comes to ICCIDs.ESIM of Hologram

EUICC

Embedded Universal Circuit Card (eUICC) is the software within the eSIM that enables remote provisioning of SIM profiles. It allows network operators to provide profiling remotely, instead of having to remove the card and insert new hardware into the device. While the eUICC was essentially developed in conjunction with the eSIM hardware, the software can also be used on traditional SIM cards.

EUICCID

With the development of eSIM, a new identification number, eUICCID. In many cases, the eSIM manufacturer may not be the company that manufactures the physical SIM and creates the profile. For example, a chip company might also decide to sell an eSIM. A mobile carrier wants to use their SIM, but wants to provide them with their own pre-developed profiles. The service provider may even work with another provider to create a profile, turning this into a two- or three-party relationship. To simplify the situation, the industry has used eUICCID to identify the physical eSIM. It’s a completely different classifier, other than ICCID, which is usually still generated with the profile.
