The Internet of Things (IoT) landscape is evolving rapidly, and with it, the technologies that power global connectivity are advancing at an unprecedented pace. One of the most impactful innovations in recent years has been the rise of eSIM (electronic SIM, sorry we don’t call it Embedded SIM, eSIM can be downloaded to a plugin (2FF, 3FF, 4FF or embedded MFF2, MFF3, MFF4) technology. As we move into 2025, new standards such as SGP.32 and advancements in remote SIM provisioning are poised to reshape the IoT connectivity market.

But what do these changes mean for IoT solution providers, device manufacturers, and enterprises that rely on connected devices? In this article, we’ll explore how emerging eSIM standards will influence IoT deployments and why staying ahead of these changes is crucial for maintaining seamless global connectivity.

The Shift from SGP.22 to SGP.32: What’s Changing?

Until now, many of the eSIM deployments for IoT devices have been based on the SGP.22 standard, which governs the remote provisioning of consumer devices with M2M (machine-to-machine) devices adoption. The SGP.22 has been popular as the eSIM profiles are easy acquire and the swap is easy however it has lacked a standardized remote management capability.

Enter SGP.32, the next-generation standard designed to standardize IoT eSIM management. SGP.32 introduces a more efficient architecture that allows for:

• Agreed upon playing field. All parties in the ecosystem agree on what components to use.
• Better Scalability: Enables the management of large-scale IoT deployments with improved profile switching and provisioning efficiency.
• Seamless Integration with SIM based solutions with the IPAe

For IoT solution providers, these improvements mean ability to deploy eSIM enabled solutions to the market and not be locked into one provider

Why eSIM Evolution Matters for IoT Deployments

The previous eSIM standards were meant for Automotive Industry and Consumer Mobile Phones creating some operational challenges to use eSIM with IoT devices:

• Non standardized deployments with some components being proprieatary
• Carrier Lock in with narrow spec deployments
• Inability to actually use eSIM to switch providers depending on business requiments

With SGP.32 and its improved automation capabilities, these pain points are addressed, ensuring that IoT devices remain connected, secure, and operational—regardless of where they’re deployed.

Implications for IoT Solution Providers and Enterprises

For IoT solution providers and enterprises managing large fleets of connected devices, the adoption of SGP.32 brings distinct competitive advantages:

Lower Total Cost of Ownership (TCO): Automation in eSIM provisioning minimizes the need for manual profile management, and standardization allows reduced sourcing costs

Faster Time-to-Market: As the ecosystem all plays by the same rules the stack can be completed with off the shelf components

Enhanced Security and Compliance: SGP.32 introduces more robust security protocols, ensuring that IoT devices comply with evolving global security regulations.

By embracing these changes early, businesses can future proof their IoT deployments and ensure uninterrupted service for their customers.

What Should You Do to Prepare?

As the transition from SGP.22 to SGP.32 gains momentum, IoT solution providers and enterprises must take proactive steps to stay ahead:

• Evaluate Your Current eSIM Architecture: Assess whether your existing infrastructure is equipped to handle the transition to SGP.32.
• Prioritize Flexibility in Connectivity Management: Look for IoT connectivity partners that offer multi-network capabilities and dynamic profile switching.
• Stay Informed on Global Regulatory Changes: Keep an eye on emerging IoT security standards and compliance requirements to ensure alignment with evolving regulations.
