The Internet of Things has been expanding at a rapid pace, connecting billions of devices across industries like agriculture, logistics, energy, and manufacturing. At the heart of this growth is eSIM technology, which provides secure, flexible, and scalable connectivity throughout a device’s lifecycle. Global SecurityTech leader Giesecke+Devrient (G+D) has highlighted how eSIM advancements are transforming efficiency, lowering operational costs, and streamlining IoT management.
Originally designed for automotive and machine-to-machine applications, eSIM has now spread across nearly all IoT domains. With new standards such as SGP.32, In-Factory Profile Provisioning (IFPP), and wider use of Private 5G networks, the way devices connect and communicate is being redefined. These innovations allow enterprises to maintain better control while adapting to changing regional and regulatory needs.
One of the key advancements is SGP.32, which replaces older SMS-based systems with IP-based communication. This shift makes IoT devices easier to manage, more adaptable, and better suited for global deployment. Enterprises can now centrally manage large fleets of both new and legacy devices without complex manual processes.
In-Factory Profile Provisioning has also emerged as a breakthrough feature. With IFPP, manufacturers can preload eSIM profiles directly during production, ensuring devices are ready for deployment. When combined with Remote SIM Provisioning, this method eliminates the need for manual configuration after manufacturing, speeding up rollout and reducing time-to-market.
Private 5G networks are another area where eSIM technology is proving valuable. Industrial environments often require reliable and vibration-resistant connectivity for machines. eSIMs enable devices to move seamlessly between private and public networks while maintaining strong connections. Through SGP.32, enterprises can also switch profiles quickly if coverage requirements change.
A major advantage of cellular connectivity through eSIM is the enhanced security it provides. Compared to Wi-Fi and Bluetooth, cellular networks operate under stricter global security standards. Companies like G+D are also offering intelligent solutions such as AirOn360, which allow time-limited connectivity. This feature helps reduce data costs by only activating connections when they are actually needed.
Simplified design and inventory management are further benefits that eSIM brings to IoT. By embedding connectivity directly into devices, the need for physical SIM cards and slots is removed. This not only reduces the bill of materials but also lowers SKU complexity. Businesses can now standardize device models across regions, making logistics smoother and more efficient.
According to Sönke Schröder, Director of Global Go-to-Market Strategy & Innovations for Connectivity & IoT at G+D, eSIM will be central to modern connectivity and manufacturing processes. He explained that the technology enhances efficiency, security, and cost savings while enabling greater digitalization of workflows. By being network-agnostic, eSIM allows devices to switch between providers multiple times over their lifecycle.
The AirOn360 platform plays a crucial role in secure provisioning. It allows enterprises to load new profiles onto devices quickly and safely, ensuring they remain flexible as business needs change. This adaptability is vital for enterprises managing fleets of devices spread across different regions and networks.
As IoT adoption accelerates, the role of eSIM is expanding beyond simple connectivity. It is becoming a strategic tool for enterprises that need to deploy and scale billions of devices with agility. Organizations can rely on eSIM to simplify operations while keeping costs under control.
The combination of IP-based standards, factory provisioning, and intelligent connectivity management ensures IoT devices can be deployed faster and more reliably. With these innovations, businesses can focus more on services and less on the technical challenges of device connectivity.
Enterprises in industries such as logistics, healthcare, and manufacturing now view eSIM not only as a connectivity enabler but also as a differentiator. The ability to streamline device management and ensure secure communications offers them an edge in competitive markets.
Looking ahead, eSIM adoption is expected to grow in line with the IoT boom. As billions of devices continue to connect, enterprises will benefit from the security, efficiency, and flexibility that eSIM technology offers. This will strengthen the foundation for future digital transformation and smarter industrial solutions.
By embracing eSIM, companies are positioning themselves to manage global IoT deployments with confidence. The technology supports agility, scalability, and long-term adaptability, making it an essential element of next-generation connectivity strategies.
