TL;DR: 100% of MNOs are on the path to deploy GSMA SGP.32, yet 80% still expect long-term cost and complexity challenges and 52% cite security and fraud risks as a major concern, according to Idemia research. The governance problem is no longer specification adoption alone, but how operators control integration, device identity, cryptographic agility and monetisation at scale.
NHIMG editorial — based on content published by Idemia: Key success factors for eSIM IoT deployments
By the numbers:
- 100% are already on the path to deploy it.
- 80% of MNOs still foresee long-term costs and complexity as their main deployment challenge.
- 71% of our study respondents said modernising BSS legacy systems is a key challenge.
Questions worth separating out
Q: How should security teams govern eSIM IoT provisioning in large deployments?
A: Security teams should govern eSIM IoT provisioning as an identity workflow, not just a telecom process.
Q: Why do long-lived IoT devices create more cryptographic risk over time?
A: Long-lived IoT devices create more cryptographic risk because the algorithms, certificates and trust assumptions used at launch may no longer be strong enough years later.
Q: What do organisations get wrong about eSIM IoT integration projects?
A: Organisations often treat eSIM IoT integration as a one-time technical rollout, when it is really an ongoing governance and lifecycle programme.
Practitioner guidance
- Map eSIM workflows to identity controls Inventory every API, portal and partner path involved in provisioning, profile download and lifecycle changes.
- Limit provisioning rights by purpose and partner Scope access so OEMs, resellers and internal teams can only perform the actions required for their role.
- Build anomaly detection for download patterns Monitor for unusual bursts, geography shifts, repeated retries and device groups requesting profiles outside expected baselines.

eSIM IoT is becoming a machine identity governance problem. The article shows that rollout success depends on more than specification compliance, because operators must control how devices, APIs and partner workflows authenticate and are authorised. That puts the topic squarely in the intersection of IoT security and identity governance, where machine identity lifecycle, entitlement scope and monitoring are the real control plane. Practitioners should stop treating eSIM management as purely telecom engineering and treat it as governed identity infrastructure.
A question worth separating out:
Q: What should operators do when eSIM management APIs are exposed to partners?
A: Operators should require least-privilege access, strong authentication, request validation and detailed logging before exposing eSIM management APIs to partners. The goal is to make every action attributable and purpose-bound, so a trusted integration cannot be reused for unauthorised provisioning or large-scale misuse. Partner convenience should never outrun access control.
