eSIM technology is no longer a futuristic concept. eSIMs are everywhere; the ignition key to a hyper-connected world. From an IoT idea to reality, eSIM is reshaping industries and redefining consumer user experiences.
From its inception in 2012, eSIM has promised flexibility, scalability and efficiency to the connected world – all with limited success. But recently we see signs that eSIM will become a cornerstone in modern connectivity.
Let’s explore the current state of eSIM, its growing adoption, and how it will become crucial in both IoT and consumer devices.
The Evolution of eSIM
From its 2012 inception as an IoT solution the standard evolved into consumer devices around 2016. Fast forward to today where new milestones are set, with the likes of Apple’s eSIM-only devices and the adaptation of other manufacturers.
The Numbers Speak for Themselves
In the consumer spectrum of eSIM:
- Over 260 operators have launched commercial eSIM services as of 2024
- Analysts project around 850 million eSIM connections globally by 2025, growing towards 6.7 billion by 2030
- Juniper Research forecasts 440% growth in travel eSIM users over the next 5 years, significantly disrupting the traditional roaming market.
Key Advantages for Consumer Use of eSIM Technology
- Convenience of switching network operators, without needing to physically replace a SIM.
- Multiple profiles stored on a single phone with easy switching capabilities between them. Particularly useful for travel allowins user to easily swap when arriving in a country, potentially saving on roaming cost and experiencing better local service.
- Dual SIM functionality allows users to have two phone numbers (with one or more operators) on one device. Convenient for separating private and business lines, and optimized coverage in areas with potty connectivity.
- Space-saving design; the eSIM eliminates the need for a physical SIM reader in the device, leading to smaller and more robust design with more space for other components e.g. battery.
But What About the IoT Devices
The IoT sector will be one of the most significant beneficiaries of eSIM technology. In connected cars, smart meters and GPS tracking devices, eSIM already facilitates easier deployment, management, and scaling of IoT solutions globally.
New and improved eSIM standards help simplify while allowing for
- Rapid deployment – eSIM’s remote provisioning capabilities allow for swift and large-scale deployments, bypassing the logistical challenges associated with physical SIM cards.
- Inventory Optimization – reduced dependencies on physical SIM cards streamline supply chain management and inventory control.
- Cost Reduction – eliminating the need for physical SIM card handling and distribution can lower operational cost.
- Unparalleled Flexibility and Control
- Dynamic Network Selection – the IoT device can seamlessly switch or be manually switched between networks based on factors like geography, coverage, cost, or performance
- Remote Profile Management – operators can modify device configuration remotely, to ensure optimal performance and security
- Lifecycle Management – eSIM technology simplifies device lifecycle management with activations, deactivations, and reconfigurations
- Global Reach and Seamless Connectivity
- Universal Connectivity – eSIM can span countries and regions, eliminating the complexity of international roaming and SIM card swaps
- Network Agnostic – enables IoT devices to work with different network technologies (2G, 3G, 4G, 5G) through a single eSIM, future-proofing deployments
- Improved Coverage – multiple network provider profiles enhances connectivity reliability and ensures uninterrupted service
How to Select eSIM for IoT Devices
Selecting the right eSIM for your IoT device involves understanding the differences between consumer and IoT/M2M eSIM standards. Some key considerations include:
- eUICC support – a necessity in your device hardware and firmware to support eSIM updates. Consideration should be given to how Over-The-Air updates are handled in general for SOTA/FOTA as compliance e.g. NIS2 compliance can be a requirement
- Cost – consider the higher cost for the eUICC hardware, and how eSIM swaps may impact your business model
- Operators – can support you on your eSIM journey with know-how, coverage, and price
