When integrating eSIMs into a Linux based embedded device, one of the questions is how to manage that eSIM. In case of SGP.21 consumer eSIM or the new SGP.31 IoT eSIM, some software component for management and download of eSIM profiles (LPA or IPA) is required. In the past, this was mostly achieved by proprietary software.

More recently, Free and Open Source Software alternatives for this have materialized, like the "lpac" software. This talk covers those projects, what you can do with them and how to integrate them in your cellular-enabled embedded device.

The talk will also compare this approach of eSIM integration with other approaches such as the venerable SGP.02 M2M eSIM or using an eUICC-integrated LPA/IPA (LPAe/IPAe).
