How eSIM platforms support the rise of IoT connectivity


With today’s mobile networks established essentially worldwide, there’s not many that do not know about the SIM cards. Short for the Subscriber Identity Module (SIM), the SIM card’s main job was to help providers identify a specific user in a mobile network. Through the SIM card, users can access different services like mobile data, and service providers can ensure specific users needing the service can access it securely. That being said, the physical SIM card is getting old. The limitations of the traditional SIM card as a hardware element are holding devices back, but fortunately, a new technology known as the embedded SIM (eSIM) and eSIM platforms will change all of that.

In today’s age, IoT (the internet of things) has been introduced to connect the devices we know together. This has offered some immense benefits. For example, with IoT, a homeowner can easily control their AC unit or heater away from home, ensuring that when they finally arrive, the AC is on and ensuring the house is at a comfortable temperature. In the business world, IoT has allowed managing things like warehouses a lot easier, where each product can be tracked effectively.

The big problem with IoT and traditional sim cards is one main hurdle: the cost. For businesses that want to integrate IoT into their devices, the cost of installing the appropriate socket, not to mention purchasing individual SIM cards, can get expensive really quickly. When a SIM card needs to be replaced, then the trouble gets worse. Other limitations like a SIM card being limited to a mobile network also present their challenges, but overall, the traditional SIM card doesn’t effectively support IoT implementations of today.

With that in mind, how exactly does eSIM solve this problem? As its name implies, an eSIM is an electronic SIM solution that eliminates the need for sockets or even a plastic SIM card. Because it is accessible through digital means, users can quickly swap between mobile providers without the need of having to replace anything. A bonus to eSIM is the fact that, because there is no specific compartment for the SIM card, the problem of dust and moisture entering a device is limited.

Another big reason eSIM is great for IoT applications is the fact that, because it follows a GSMA specification with stringent certifications, security is not compromised. Pair this with eSIM platform’s excellent flexibility in the use of many applications, this is the perfect solution for any company looking to utilize a SIM card’s capability without wanting to deal with the troubles of a physical SIM card.


Simply put, thanks to the eSIM’s capabilities and platforms, introducing and implementing industrial IoT strategies have become a lot more feasible. Without having to deal with physical cards or worry over implementing dedicated slots for said cards, companies can quickly and easily integrate eSIM into their IoT use cases. With the added benefit of managing all these eSIMs from a single point with the ability to change profiles with a click of a button, companies can deploy IoT solutions much more efficiently. In the long run, this helps boost productivity, not to mention the savings that can further support and improve IoT systems.
