LPA #

The LPA (Local Profile Assistant) is a piece of software in the GSMA Consumer (SGP.22) eSIM architecture, which runs on the UE (User Equipment, Phone, Modem) and interfaces the SM-DP+ (via HTTPS) and the eUICC.

Its purpose is to

• Manage eSIM profiles (enable, disable, delete)
• Download eSIM profiles from the SM-DP+
• Retrieve notifications from the eUICC and send them to the SM-DP+

A LPA can either bei a LPAd (LPA on the device) or LPAe (LPA embedded inside the eUICC).
