What is eSIM?

An eSIM (embedded SIM) is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical SIM card. It's commonly used in smartphones, tablets, and wearables to provide connectivity, and it can store multiple profiles, allowing users to switch between different carriers or plans.

What other technologies are related to eSIM?

eSIM Competitor Technologies

ISIM

ISIM (IMS Subscriber Identity Module) is an application that runs on a UICC (like a SIM or eSIM) and is used to authenticate a user to the IMS network. While eSIM and ISIM serve different purposes, they both relate to subscriber identity, making them potentially competing technologies in certain contexts, although ISIM needs a UICC.

eSIM Complementary Technologies

eUICC

eUICC (Embedded Universal Integrated Circuit Card) is the hardware on which the eSIM profile resides. It is a crucial component of eSIM technology, acting as a secure element that stores multiple operator profiles and enables remote SIM provisioning. Therefore, it strongly complements eSIM.

GSMA

GSMA is the association that defines the standards and specifications for eSIM technology (including eUICC and remote provisioning). They are essential for the development and interoperability of eSIMs, thus strongly complementary.
