OsmoDevCon 2024: "Anatomy of the eSIM Profile"

I've presented a talk Anatomy of the eSIM Profile as part of the OsmoDevCon 2024 conference on Open Source Mobile Communications.

In the eSIM universe, eSIM profiles are the virtualised content of a classic USIM (possibly with ISIM, CSIM, applets, etc.).

Let's have a look what an eSIM profile is:

  • how is the data structured / organized?

  • what data can be represented in it?

  • how to handle features provided by eUICC, how can the eSIM profile mandate some of them?

  • how does personalization of eSIM profiles work?

There is also hands-on navigation through profiles, based on the pySim.esim.saip module.
