TCA eSIM Interoperability Service

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.
