Tech Tips #19: SGP.32 — The Future of eSIM for IoT? Yes… But Not the Full Answer
IoT deployments are becoming more complex. SGP.32 promises to simplify provisioning but there are caveats.
Tech Tip: Don't rely on SGP.32 alone — combine it with a robust connectivity strategy.
SGP.32 is the GSMA’s newest remote SIM provisioning (RSP) standard, tailored for the demands of IoT deployments. It builds on the strengths of earlier standards (SGP.02 for M2M and SGP.22 for Consumer), but goes further offering a scalable, low-touch solution for devices with no screens, minimal power, and long deployment lifecycles.
Sounds perfect, right? Almost.
What SGP.32 Delivers
- Remote profile switching without operator approval
- Uses an IoT Profile Assistant (IPA) + eSIM IoT Remote Manager (eIM) to manage eSIMs
- Simplifies compliance with roaming and localisation regulations
This new standard gives enterprises more control over their fleet connectivity especially when devices are deployed globally, remotely, or across multiple networks. Read the GSMA’s full SGP.32 v1.2 specification
Why SGP.32 Needs a Strategy?
SGP.32 is a step forward, but challenges remain:
- It’s new — adoption and certification are still underway (expected in 2025)
- Enterprises still need commercial agreements with multiple MNOs
- Back-end integration is complex (VPNs, APNs, SLAs, compliance)
- Costs add up — profile hosting/switching can reach $1/month/device
- Localisation still requires regulatory-compliant local profiles
