eSIM: facts & myths

As IoT capabilities and mobile connectivity requirements have changed in recent years, the eSIM has been the ultimate answer. While it can certainly help avoid many of the current challenges that IoT providers are facing, there are still a few more misconceptions that need to be cleared up. The first step in implementing a new technology is to understand its capabilities as well as the ideal use cases. In this article, we discuss four well-known myths and facts about the eSIM.

Myth 2: consumer eSIMs and IoT eSIMs are the same

Yes, with both technologies, provider profiles can be set up and managed remotely. However, the way in which the profile is requested differs. For consumers, it is the end user who chooses and applies for the desired provider. This is usually arranged per device, so a central overview of several devices and their profiles is not necessary.

IoT devices are managed differently. These are managed remotely by the end user of the enterprise. It is essential that they have a remote way to push and manage the required provider profile to their IoT device / SIM card.

Fact: Consumer and IoT eSIM specifications are different and therefore these product / SIM cards are not the same.

Myth 4: eSIM is the same as Multi-IMSI

Multi-IMSI connectivity solutions are similar to the eSIM; they are able to switch to multiple provider networks. But with a multi-IMSI solution, this is achieved by replacing or updating the IMSI within the profile instead of downloading a new profile in case of an eSIM. Unlike eSIMS, multi-IMSI solutions are proprietary, without interoperability between carriers and service providers.

Fact: Multi-IMSI is a proprietary technology with no defined standards or specifications. eSIM has a GSMA-defined Remote SIM technology where interoperability between carriers and service providers is possible.
