Blog from COMPRION: A fresh approach to creating eSIM profiles

eSIM profiles are the critical data objects when it comes to attaching devices to networks successfully. As the factors influencing network connectivity are manifold (different devices, eUICCs, networks … you name it), working on suitable eSIM profiles can be tricky. This becomes even more annoying when you take into consideration that usually changing the code of a profile means stepping through the complete file system: A very laborious task, time-consuming, and prone to many repetitions, until you finally get a profile that works. And with every new requirement, for example, the change of one factor, this process will start over again.

Now, you can break this tedious routine with a new method, which is based on reusing the building blocks of proven eSIM profiles for the creation of new profiles. In contrast to working your way through the file system, you compose new profiles by using qualified blocks of tried and tested profiles. You access the profile data in a very transparent way in the form of profile elements – in full compliance with the structure used in the SIMalliance specifications referenced by the GSMA. A well-developed editor supports you with import/export functions and a clearly structured work area for making fast adjustments to the code. Furthermore, the profile elements are validated automatically in real time, and so you get immediate feedback on the applied modifications. Soon, there will also be the option of generating validation reports for profiles. This new feature will enable you to get a quick, comprehensive overview and is especially useful when dealing with newly imported profiles.

The new approach gives you a choice when adapting your eSIM profiles to new requirements: modify existing profiles step-by-step, one line of code after another, or use the convenient method of profile composition, including fast minor adjustments.
