What You Need to Know About eSIM for IoT

eSIM for IoT

The Internet of Things (IoT) is transforming the world as we know it. From industrial IoT (incl. machines and equipment) to consumer IoT (incl. all sorts of connected devices), IoT is making our world smarter. And while this is true for most modern technology, it’s doubly true for eSIMs. Considering the impact of the IoT on eSIMs, we thought it would be useful to put together a short discussion on this subject. If this is something that you want to learn more about, read on for a brief breakdown of what you need to know about eSIM for IoT.

What Is an eSIM?

Simply put, eSIM allows you to set your wireless carrier and data plan through software, so you don’t have to go to the store or wait for the mail. If you have an eSIM device, you can change your carrier or plan by activating a code or scanning a QR code. The word “eSIM” just means that SIM cards are built (“embedded”) into the device, and there’s no physical swapping over required by the user.

What Are the Benefits of eSIM for IoT?

Now that you know what an eSIM is, it’s time to talk about how eSIMs can benefit you. Here are a few of the most significant benefits of eSIM for IoT:

  • eSIMs are great for future-proofing connected devices. IoT devices that are deployed over a long period of time, or those that utilize SIM services over a long period of time, are protected from the impact of evolving network technologies, sunsets, or service terminations by eliminating technical, carrier, or SIM lock-ins with an eSIM.
  • eSIMs eliminate the need to switch SIMs. Remote provisioning to different carrier profiles or network technologies enables organizations to change the profiles of their SIM cards without replacing them
  • eSIMs streamline logistics’ management. Organizations no longer need to spend money, time, and effort transporting damaged or obsolete SIMs between remote businesses and their primary location.
  • eSIMs allow you to maximize your return on IoT investments. The reduced costs, improved operational and logistical efficiencies, and minimized total cost of ownership create a foundation for maximized returns on IoT investments.

What Is the Future of eSIMs?

Some major cellular companies are developing eSIM solutions. However, it’s important to note that there are limited specific capabilities of each company, but these single-company offerings do not completely address the challenges of long-term global eSIM adoption. Although there are still technical challenges to solving the problems with eSIM technology, the sheer potential of simplified deployments that can support new network technologies or complex logistical deployments are exciting.

eSIM solutions will mitigate the risk of things becoming useless when their networks go offline, or when the technology changes, while minimizing the cost of ownership over their lifetime. This will maximize return on customers’ IoT investments.


We hope this article proves to be useful when it comes to helping you further your understanding of eSIMs. As you can see the eSIM will drastically transform how we interact with the world in the age of the IoT.
