How eSIM technology drives the Rise of IoT Devices

eSIM IoT devices

The Internet of Things (IoT) is becoming one of the hottest topics today and is probably one of the biggest innovations to come in recent years. It’s basically a concept where everyday things are somehow connected through the internet and can be managed and manipulated through it. One little piece of technology is actually driving the growth of IoT, and that’s eSIM technology. The application of eSIM to any device isn’t exactly new, but it’s the missing component that will allow IoT to thrive and grow in this new ecosystem. Let’s look at the relationship between eSIM and IoT and why we should look forward to it.

The Potential of IoT Applications

Imagine those scenes in sci-fi movies where phones, watches, desks, bus stops, even vacuum cleaners are connected to the internet and can be accessed whenever or wherever you are. Those scenes may no longer stay as fiction with the rate IoT applications are growing.

Because of eSIM technology, the potential for IoT to be applied in everyday life has become even more possible. eSIMs and their anticipated evolution will pave the way for remote manageability and data transferring to any device quickly and efficiently. Here are some of the expected advantages of using eSIM on IoT-enabled devices.

  • Security – The ability of eSIM to switch between several profiles by downloading them into an embedded chip has been proven to be of great use to any device that supports it. Unlike a regular SIM card, which is easy to remove, an eSIM will always be intact and is hardwired into the device. This makes any IoT device traceable whenever it is turned on, which discourages theft.
  • Design Improvements – One of the biggest challenges of any manufacturer trying to build IoT devices is space availability. In the case of smartphones, newer models seem to run out of space for other functions. Eventually, this will happen to SIM cards as well. Since eSIM measures around 2.5 mm x 2.5 mm, which is about 30% smaller than your typical nano-SIM card, it’s easier to incorporate SIM functionality into any device, not just smartphones. Imagine wearables, healthcare devices, or beacons, and tracking devices can now have an embedded SIM that has access to the internet.
  • Longevity – SIM cards have long been deemed to be bulky and a waste of precious space. Having a SIM port that needs to be removed doesn’t help since it compromises any device’s casing integrity. This makes it harder for manufacturers to create products that are waterproof and can withstand the elements. With an embedded SIM, however, this problem can be solved completely. IoT gadgets are often exposed to the elements but are able to withstand moisture, extreme temperatures, vibration, or even physical impact since manufacturers can make these devices sealed tight at all times. This is only possible by completely discarding SIM ports and replacing them with eSIMs.
  • Interoperability –  Before eSIM technology was a thing, traditional SIM cards required significant logistics to maintain SIM connectivity and provision devices. Nowadays, you can do all that from a single IoT platform in a matter of minutes. Any IoT device that uses eSIM technology can be moved anywhere in the world and joined to other IoT networks. There’s no need to switch SIM cards. This reduces the infrastructural load on IoT deployment significantly.


The combination of IoT and eSIM technology is truly a match made in heaven. With the continued development of both pieces of technology, we are about to experience the IoT revolution.
