2022 was a landmark year for the eSIM ecosystem. eSIM adoption has accelerated around the world and is now rapidly moving towards becoming the preferred mode of connectivity. Consumer interest in eSIM is at an all-time high, profile downloads have increased exponentially and newer players are entering the market – all signs of an ecosystem on the rise.
Most premium smartphones now come with an embedded SIM (eSIM) as it is more advantageous than a physical SIM for OEMs, operators and consumers. We’ve already seen an eSIM-only iPhone 14 in September last year. It is possible that in the coming years, most premium smartphones may not have a physical SIM at all. But it is not just smartphones, even companion devices like tablets, smartwatches and other IoT devices are now adopting eSIM. However, because eSIMs are not removable like physical SIMs, testing for profile suitability and interoperability becomes extremely important.
But how does eSIM testing work? What is the process? Which companies help in such testing? We discuss all that and more in our podcast with Comprion, which is a German company that specializes in eSIM testing.
In the latest episode of “The Counterpoint Podcast,” host Ankit Malhotra is joined by Marcus Dormanns, Director of Product Management and Business Development at Comprion. The discussion touches on several topics including the technical process of testing an eSIM, interoperability with different network providers, the time taken for testing, and more.
