Interoperability Issues: Understanding the Causes and Impacts

Several components interact with each other in the process of remote (e)SIM provisioning:

  • The SM-DP+ Remote SIM Provisioning server interacts with the device's LPA and eUICC.
  • The eSIM profile, along with all its configurations, interacts with the eUICC and the mobile baseband processor.

While there are standardized technical specifications and test protocols available for the SM-DP+, LPA, eUICC, and eSIM profile, real-world scenarios still present a risk of interoperability issues:

  • Technical specifications may have ambiguities that could lead to different interpretations.
  • Testing individual components against their specifications in isolation is a good first step, but it may not test interoperability between different components.
  • Different versions of technical specifications for various components can create compatibility issues when they come together.
  • The expert who creates the eSIM profile may have technical specifications in mind, but the profile is rarely checked thoroughly against the specifications.


The Importance of Proactively Preventing Interoperability Issues 

Ensuring that your products and services work seamlessly with those of your partners is essential to maintain your business's reputation and profitability. Interoperability issues can lead to substantial customer dissatisfaction and lost revenue. However, by proactively preventing these issues, you can avoid the need to spend a significant amount of time and resources fixing them later on.

  2. Self-testing in COMPRION's office in Paderborn, Germany
    Visit us and get access to the test device portfolio and do the testing yourself.
  3. Remote Testing
    We set-up a Microsoft Teams session with you, mirror the screen of the test devices and provide you with remote control. COMPRION staff is facilitating this testing process for whatever remains to be done physically.

In any case, as preparation of the testing session we'll be in contact to align on all aspects of the intended testing, e.g. which test devices shall be used. As an added benefit, members of the Trusted Connectivity Alliance (TCA) enjoy a reduced rate on our testing service.

 Test devices for the service are selected mainly based on:

  • Market share
  • Potential diversity of employed eUICCs and LPA implementations

The below listed devices are available for the testing service. The portfolio of test devices is extended over time.
