When it comes to connectivity, the future looks bright
The advent of eSIM (embedded SIM) technology represents a significant leap forward, particularly in the realm of Internet of Things (IoT) connectivity. This blog explores the intricacies of such technology, its benefits, and its potential to revolutionise various sectors, drawing on insights from industry experts Steven Lowe, Gamma’s Product Director Mobile, and Rob Kittler, Gamma’s Head of Connectivity Practice.
What is eSIM technology?
Let’s start at the beginning; what exactly IS eSIM technology? Well, it fundamentally changes how devices connect to networks. Unlike traditional SIM cards, which are physical components that need to be inserted and swapped out manually, eSIMs are embedded directly into the device. This allows for over-the-air (OTA) profile downloads and remote management, providing unprecedented flexibility and efficiency.
Steven Lowe explains, “The way it works is that there is still a SIM chip, so it’s still a piece of physical hardware, but it’s actually soldered into the device by the manufacturer. When the customer selects their airtime package, whether we do a deal with them or the channel partner sells them Gamma Mobile, they will be able to download the eSIM profile.”
Benefits of eSIM technology
What are they then? The boons of this kind of technology are manifold. One of the primary benefits is the environmental impact. Traditional SIM cards generate a significant amount of plastic waste, whereas eSIMs eliminate this issue. Steven points out, “From an ESG point of view, when the customer wants to change their provider, they can do that without having to put a new SIM card into the device. So, you use the same SIM chip, but a different profile is just downloaded onto that SIM.”
Not only that, eSIM technology simplifies the process of switching network providers. This is particularly beneficial for businesses that require flexible connectivity solutions. “We’re always trying to make our network better, make our product better. It’s one of those major steps forward,” Steven adds.
Use cases for eSIM technology
The potential applications of eSIM technology are vast, spanning various industries and use cases. For instance, in the realm of IoT, they can significantly streamline operations. Rob Kittler shares an example, “We have a client putting SIMs in devices at the top of streetlights to measure the level of light. The idea is to only turn the streetlight on when the light level falls below a certain point.”
Another compelling use case involves routers for postal services. Rob elaborates, “We have a customer, Alps Alpine, a manufacturer of routers for postal services worldwide. Previously, you had to use different SIM cards for each country to get the coverage for narrowband IoT. With the eSIM functionality, you can install the chip in the router and provide it globally, selecting the narrowband IoT provider in any country over the air.”
Enhanced connectivity and security
eSIM technology not only enhances connectivity but also bolsters security. With the ability to manage SIM profiles remotely, businesses can ensure secure and reliable connections for their devices. Steven discusses a proof of concept they are running, “We’re running a proof of concept for one of the most recognisable brands in the UK. They have 2,500 to 3,000 vehicles that travel around the UK, and connectivity is essential for them. If they lose connectivity, it costs them a huge amount of money.”
Rob further highlights the importance of security in specific use cases, “Another use case is security, particularly for lone workers or security guards in areas with difficult coverage. The Fusion IoT SIM provides access to all networks, picking up the strongest signal. Combining this with mobile device management and geofencing, security management can draw a geofence around the security guard’s location and track their movements.”
The road ahead
The future of eSIM and IoT technology is bright, with continuous advancements poised to unlock new possibilities. One exciting development on the horizon is the integration of satellite connectivity. “Through Fusion, we’ll be adding satellite connectivity this year as well,” says Steven. This will ensure 100% global coverage, which is crucial for asset tracking and other applications in remote areas.
As technology advances, ethical considerations around data privacy and security will become increasingly important. Rob notes, “Governments and regulators need to step up and ensure things are done ethically for the benefit of humanity. Technology can be transformative, but we need to keep pace with safeguards.”
It’s life eSIM, but not as we know it
The implementation of eSIM technology represents a significant step forward in the world of connectivity, offering numerous benefits from environmental impact to enhanced flexibility and security. As industries continue to explore the potential of eSIMs, the possibilities for innovation and efficiency are virtually limitless.
By leveraging eSIM technology, businesses can ensure they remain at the forefront of technological advancements, providing their customers with the best possible connectivity solutions. As Rob succinctly puts it, “Our job is to provide the right connection in the right location with the right application.”
As we look to the future, the integration of eSIM and IoT technologies promises to revolutionise the way we connect and interact with the world around us, paving the way for a more connected and efficient future.
