How wireless eSIMs Will Pave the Way for the Evolution of IoT

Celitech eSIM API

Ever since the development of wireless eSIMs, it has been put forward as the next significant step forward in cellular data API’s for connected IoT devices and gadgets. Currently, eSIMs are used predominantly in smartphones, laptops, and other similar devices.

However, with the expansion of eSIM applications, it will undoubtedly become the next step in the evolution of IoT devices. Let’s explore how this relationship between IoT devices and eSIMs is possible and how the former could benefit from the latter.

Better Flexibility in Design

Traditional SIM cards have been continuing the trend of miniaturization for quite some time, but only eSIM technology was able to take the concept to the extreme by producing eSIM chips that are five times smaller than nano-SIM cards. This significant difference in size allows IoT devices more freedom and growth in their design.

Considering that there’s no limit to the size of IoT devices, wireless eSIMs could make a huge difference in smaller IoT devices. IoT designers can now integrate technology into their devices that will better protect data and privacy because of the embedded eSIM chip technology.

Improved Data Security

By removing the size factor of SIM cards, there’s a significantly lesser risk of data breaches or SIM swaps. But aside from the reduction in size, the chips themselves allow designers to bolster their data security measures. With the overwhelming number of hacking incidents and identity theft involving SIM cards in recent years, eSIM technology has the potential to mitigate the damage sustained from such risks.

The mere fact that an eSIM chip is embedded and cannot be removed under any circumstance offers one of the most significant security benefits for IoT devices. Being hardwired into a device means it can be traceable whenever the device is turned on. Also, cell phone cloning and port-out scams are nearly impossible to pull off on any device with an embedded SIM.

For people traveling to other countries, having an eSIM profile is infinitely more convenient and secure since they no longer have to swap out their SIM for a new one. This eliminates the need to remove SIM cards from the device and risk losing them.

Easier Adoption and Implementation

Finally, the most crucial benefit of using wireless eSIMs on IoT devices is its easier adoption and implementation. Different physical SIM cards vary in standards and sizes and service activation can happen only when the SIM card is physically inserted in the device. With built-in eSIMs, activation is much easier, using digital mechanisms such as QR code, manual activation code or a carrier app.

There’s also the added bonus of changing operator subscriptions without taking the device back to the store or physically removing the SIM card. Custom profiles on eSIMs exist to solve that particular problem.


With these benefits fueling the growth of eSIM technology, the development of IoT devices will also continue. From home-based tech, connected vehicles, and manufacturing to remote monitoring devices, there’s just no limit to connecting electronic devices through the use of IoT. The mass adoption of consumer and industrial IoT is very much on its way with the help of wireless eSIMs.
