Scaling Cellular IoT Globally? eSIM + SGP.32 Changes Everything

Cellular IoT is entering its scale phase but global deployments still run into the same barriers: roaming restrictions, provisioning complexity, fragmented SKUs and increasing security and compliance pressure.

A new market report from IoT Analytics and Giesecke+Devrient (G+D) explains how these challenges are now being addressed through eSIM/iSIM, Remote SIM Provisioning (RSP) and the new GSMA SGP.32 standard, making large-scale, cross-border cellular IoT deployments far more practical and secure. Key insights include:

1. Global IoT devices are forecast to grow to ~39B by 2030, with cellular IoT connections projected to reach 9.1B by 2030.
2. Why global scaling has been blocked by roaming restrictions and fragmented operator requirements, and how eSIM/iSIM with RSP enables dynamic switching to local profiles.
3. How In-Factory Profile Provisioning (IFPP / SGP.41/42) enables “connectivity-ready” devices and reduces costly SKU fragmentation.
4. Why SGP.32 is built specifically for IoT (headless, constrained devices) and enables more reliable, automated provisioning than legacy standards.
5. Why leading enterprises are shifting towards centralised orchestration platforms to manage provisioning, policies, diagnostics, and profile switching from one console.

For any organisation deploying IoT at scale, the conclusion is clear: Connectivity is moving from “deployment friction” to “connectivity readiness”, and SGP.32 is a key enabler. Read the report to learn how eSIM, RSP and SGP.32 unlock scalable, secure global cellular IoT:
