Some major network operators such as Reliance Jio and Airtel have quickly adopted this convenient approach, streamlining the activation of eSIMs for a hassle-free user experience. This allows consumers faster activation than physical SIM cards, reducing wait time.

5.    What is needed for eSIM functionality?

As defined by GSMA eSIM Standards, which Kigen has been collaborating to develop, there are four main components of a GSMA-compliant eSIM architecture:

· The eUICC is the software that allows provisioning
· The Local Profile Assistant (LPA) provides a list of installed profiles and when combined with the SMDP+, acts as a local proxy
· The eSIM profile stores the user’s subscription and network settings and allows the user to connect to the corresponding mobile network
· The Subscription Manager Data Preparation platform (aka SM-DP+, i.e., the eSIM subscription management server downloads the eSIM profile stored securely on the eUICC. This is done via a GSMA-certified SAS-UP and SAS-SM data center. Once the operator’s BSS creates the subscription, it informs the SM-DP+ about its availability and requires completing an eSIM profile.
