eUICC and eSIM: are they the identical factor? One could be forgiven for pondering that eUICC and eSIM are the identical issues, on condition that they’re getting used interchangeably by many media websites and blogs. The fact is, nevertheless, that they’re two totally different applied sciences.
This text will outline what eSIM and eUICC are speak concerning the totally different advantages of every.
What Is eSIM?
SIM stands for Subscriber Id Module and is usually used to discuss with the small card-shaped chip that’s inserted into smartphones and different mobile-connected gadgets. The SIM allows a tool to be acknowledged on the provider community and recognized by its quantity.
Conventional SIM playing cards have been via a couple of iterations all through the lifecycle of the know-how. It’s maybe exhausting to think about now, however the first SIM resembled a bank card in measurement and weight! That is the primary kind issue of SIM, or 1FF, as referred to within the business.
Following types of SIM have been the mini-SIM (second kind issue, or 2FF), micro-SIM (3FF), and most lately, the nano-SIM (4FF).
There may be now additionally one other kind issue, the MFF2, that are embedded SIMs soldered onto the gadget circuit board. That is the popular kind issue for linked gadgets that transfer quite a lot of work in very harsh situations.
Confusion arises when folks assume that an embedded SIM (MFF2) has distant provisioning capabilities (eUICC) as a result of MFF2 and eUICC are referred to as eSIM. So which one is eSIM?
To keep away from any confusion, we advise the next manner of wanting on the definition: “eSIM is the entire service – SIM + eUICC + platform; eUICC is the software program that permits provisioning.”
eSIM is a know-how that may be current no matter kind issue. Take the comparatively new iPhone XR, for instance; it accommodates a detachable SIM and has an eSIM service built-in, permitting customers to buy a plan from one other provider and use it alongside their contracted calls, messaging, and information plan.
To sum it up, eUICC is the software program that permits a SIM to provision cell community operators remotely, whereas eSIM is the entire service ecosystem. Neither is linked to the MFF2 kind issue.
eUICC vs UICC
It is perhaps useful to attract a comparability between outdated and new when eUICC.
The Common Built-in Circuit Card (UICC) does much more than simply the Subscriber Id Module (SIM). It runs the SIM utility whereas storing varied data items such because the consumer’s contacts record, enabling cell information, and managing information roaming throughout a number of carriers.
So, what’s the distinction between UICC and eUICC?
eUICC stands for Embedded Common Built-in Circuit Card. Nonetheless, eUICC is a SIM element that may be current in any SIM kind issue to allow the eSIM service, together with embedded. Because of this many companies confuse the embedded SIM MFF2 with an eUICC.
Probably the most notable profit of getting an eUICC-enabled SIM card is the flexibility to run over-the-air (OTA) provisioning of a number of community operator profiles from a central administration level. As soon as provisioned, the SIM profiles on the cardboard might be remotely managed and deleted if mandatory.
OTA provisioning and administration affords a degree of flexibility that was not doable earlier than eUICC was invented. Consumer gadgets with an eSIM service will also be migrated of their a whole lot in a matter of moments. We’re nonetheless solely within the early levels of the know-how’s lifecycle.
