SIM cards are identified on their individual operator networks by a unique international mobile subscriber identity (IMSI). Mobile network operators connect mobile phone calls and communicate with their market SIM cards using their IMSIs. The format is: The first three digits represent the Mobile country code (MCC).
An eSIM ( embedded SIM) is a form of SIM card that is embedded directly into a device. Instead of an integrated circuit located on a removable SIM card, typically made of PVC, an eSIM consists of software installed onto an eUICC chip permanently attached to a device. If the eSIM is eUICC-compatible, it can be re-programmed with new SIM information.
The Apple SIM is known as a Removable SIM with Remote Provisioning [4] – it is a special SIM card that may be configured with different operator profiles. This is in contrast to an embedded SIM, which is not removable and may also be remotely provisioned. It appears that Apple has begun to include both types of SIM in their newer devices.

Several IoT products like gateways are ...
The W-SIM core module is an extended version of a SIM card, containing not only user data but also all the transmission technology needed for a mobile device to work. A terminal device developer can build a customized terminal without the design and development of a radio module, and users can change to a different radio module W-SIM without ...

[1] It also defines the Integrated Circuit Card Identifier ( ICCID ), which is used in Subscriber Identity Modules (SIMs, including SIM cards and eSIMs. [2] The standard was first developed in 1988 by what became the ...
This is essentially a description of the IMSI. How could an HLR be identified by a hardware identifier when the HLR may change during the life of a SIM card? I believe that the SSN portion should be deleted. The ICCID portion is correct. I believe that this is the identifier for SIM (and R-UIM) cards. The page should therefore be the ICCID page.
