eSIM trends and future growth in industrial IoT markets

February 2026

Introduction

The global connectivity landscape is undergoing rapid digitalisation, and GSMA-standardised eSIM technology is becoming a key enabler of this transformation. While consumer devices initially drove awareness of eSIM, the most significant long-term impact is now emerging in industrial IoT environments, where organisations manage large fleets of connected assets across multiple regions.

Rising demand for flexible industrial connectivity

Industrial IoT markets are expanding at an unprecedented rate due to smarter infrastructure, automation, and data-driven operations. Sectors such as manufacturing, energy, logistics, healthcare, and smart cities increasingly rely on devices that must remain connected for many years. Traditional SIM cards require physical access for installation or replacement, which is costly and often impractical once equipment is deployed in the field. eSIM removes these constraints by allowing credentials to be provisioned and updated remotely, providing the operational agility that modern industries require.

Key market trends driving adoption

Several clear trends are accelerating the use of eSIM within industrial IoT:

• Global device deployments: Equipment is frequently manufactured in one country and activated in another. eSIM allows a single product stock keeping unit (SKU) to support multiple operators worldwide without complex pre-configuration.
• Multi-network strategies: Enterprises seek resilience by avoiding dependence on a single carrier. Embedded SIM profiles can be switched as coverage conditions change.
• Long-life devices: Smart meters, EV chargers, security systems, and telematics units often remain in service for a decade or more. Remote provisioning ensures connectivity can evolve over the device lifetime.
• Improved security requirements: Industrial systems require tamper-resistant authentication. The eSIM’s embedded secure element offers stronger protection than removable cards.
• Sustainability pressures: Reducing plastic SIM production and transport aligns with corporate ESG goals, an increasingly important consideration for large-scale projects.

Next-generation standards enabling growth

The GSMA continues to develop specifications to further support industrial IoT. Today’s deployments are largely based on SGP.22, which defines the eUICC architecture for IoT remote SIM provisioning. Looking ahead, SGP.32 introduces a simplified and more scalable framework designed for massive industrial device volumes. This new generation architecture reduces infrastructure complexity and lowers barriers for manufacturers and service providers to embed connectivity by default. Such advancements are expected to accelerate adoption across lower-power and constrained IoT devices.

Future growth outlook

Analysts predict that billions of industrial IoT connections will be provisioned using eSIM in the coming years. As 5G private networks, LPWA technologies, and global roaming ecosystems mature, enterprises will require even greater control over how and where devices connect. eSIM is uniquely positioned to support these needs, enabling:

• Faster onboarding of industrial equipment
• Reduced operational and maintenance costs
• Easier transitions between public and private networks
• More reliable international supply chains
• New business models for managed IoT services

Conclusion

The shift toward embedded, remotely managed eSIM technology is no longer optional for industrial IoT. It represents a foundational component of future connected infrastructure. By continuing to promote interoperability and security through standards such as SGP.22 and SGP.32, the GSMA is helping industries unlock the full potential of digital transformation and sustainable global IoT growth.
