Streamlining Test Automation with eSIM Technology

In the fast-paced world of telecommunications and testing, SEGRON is committed to ensuring that we are always at the cutting edge of technology. That is why eSIM support plays a significant role in the field of test automation to simulate various subscriber profiles in many different test locations.

Bridging the Gap: The eSIM Revolution

The Shift from Physical SIMs to eSIMs

Traditionally, testing relied on physical SIM cards, but their limitations were all too familiar. They are costly to procure, maintain, and susceptible to hardware failures, leading to testing downtime. This is where eSIMs, or embedded SIMs, come into play. eSIMs eliminate the need for physical cards. Instead, they depend on digital profiles that can be effortlessly downloaded onto your testing devices. This transition presents a multitude of advantages, notably in cost-efficiency.

A major advantage of the eSIM over the conventional SIM card is the ability to change the SIM profile – especially the operator contract – remotely without having to change the eSIM itself. This is extremely important for the testing with different subscriber profiles as device manufacturers or communication service providers can store several operator profiles on a device and switch between them remotely – even if only one profile can be used at a time.

The Motivation Behind eSIM Integration

What motivates this transition is not just a simple change in SIM cards. It is a comprehensive shift in how connectivity is managed. Here is why this shift is a game-changer for our customers:

- Local eSIM Multiplexing

Our local eSIM multiplexing approach empowers our customers to take control of eSIM profiles stored in the eSIM chip on a device. The activation of the desired eSIM profile is controlled by the test cases.

On Android devices we can switch between 6 eSIM profiles, and on iOS ones between 8. The eSIM profiles stay on the device and are activated and deactived per test, hence we talk about local eSIM multiplexing.
