The role of eSIMs in expanding IoT and connected device markets

April 2026

Introduction

The GSMA eSIM specification was developed not just for smartphones, but to enable broad IoT growth. By facilitating remote provisioning for connected devices, eSIMs help manufacturers deploy products globally without the constraint of traditional SIM logistics.

IoT-specific features

A dedicated component — the eIM (embedded IoT Manager) and the IoT Profile Assistant (IPA) optimise profile downloads and management for IoT use cases, where devices may lack complex user interfaces.

Benefits for IoT deployments

• Zero-touch provisioning: less manual intervention during deployment.
• Scalability: easier large-scale rollouts.
• Reliability: embedded architecture improves durability for industrial environments.
• Flexibility: devices can switch connectivity profiles as coverage landscapes evolve.

Business impact

For OEMs and network providers, eSIMs unlock new global markets and reduce barriers to entry for next-generation IoT products. Its standardised nature enhances interoperability across platforms and regions.
