One of the most significant advantages of \glspl{esim} is the ability to download and install profiles remotely without physically swapping the card. This process, known as \gls{rsp}, is defined by the GSMA in specification SGP.22~\cite{gsma_sgp22_2023, gsma_sgp22_2024, gsma_sgp22_2025}. The key components of the RSP ecosystem are the \gls{lpa}, the \gls{smdpp}, and, to a lesser extent in consumer deployments, the \gls{smds}.
The \gls{lpa} is a user-facing application on the UE that interacts with the \gls{euicc}, enabling users to initiate profile provisioning and perform lifecycle management operations such as enabling, disabling, or deleting profiles. The \gls{smdpp} is a server—operated by an eUICC manufacturer, MNO, or third party—that securely hosts eSIM profiles and makes them available for download. The \gls{smds} facilitates the “push” provisioning approach but is less common in consumer scenarios.
