Why SGP.32 makes unified management more important
SGP.32 introduces new possibilities for managing eSIM profiles remotely, but it also adds workflows that must be coordinated with existing connectivity operations. This post explains how connectivity management, eSIM orchestration, SIM-level resilience and operational support can work together to simplify a mixed IoT estate.
A growing IoT estate may span several mobile operators, connectivity management platforms and remote SIM-provisioning systems. Bringing these systems into a consistent operational view helps organisations manage subscriptions, usage, profile status and service exceptions while retaining the capabilities and provider relationships their estate needs.
SGP.32 addresses the remote provisioning and management of eSIM profiles in IoT devices, but those profile-management actions do not operate in isolation. They need to be coordinated with existing physical SIM estates, operator subscriptions, connectivity platforms and operational support processes. For example, changing a profile does not by itself ensure that the corresponding subscription and connectivity settings are ready to provide a working connection.
The operational model therefore matters as much as the individual technology. Exceptions need clear ownership and a consistent process for resolution.
Unified management across a multi-operator estate
CSL’s platforms help organisations simplify connectivity management across a mixed IoT estate. Supported operator and platform integrations bring greater consistency to day-to-day operations while preserving flexibility over connectivity providers.
CSL’s role extends beyond managing the connectivity it supplies. Customers can also bring supported services from their existing operator relationships into a more consistent management model, reducing fragmentation while retaining their existing contracts and connectivity arrangements.
- CSL managed connectivity. Bring together CSL connectivity, management capabilities and operational support as a managed service under one customer relationship.
- Existing operator connectivity. Use CSL’s platforms to simplify management of supported services from your existing operators, while retaining control of those contractual relationships.
The diagram below uses the CSL IoTM Platform as an example of how management, connectivity and resilience can work together.

Layers of a multi-operator estate: who provides each part
Figure 1 – How the orchestration, connectivity and resilience layers fit together
This example brings together CSL-supplied connectivity and supported services from existing operators, with SGP.32 profile management and rSIM resilience providing complementary capabilities.
The CSL IoTM Platform provides access to 100+ mobile operators, with management and orchestration capabilities that help simplify supported connectivity arrangements across a multi-operator estate. Alongside these platform capabilities, CSL directly manages millions of active connections across critical IoT applications.
Bringing eSIM orchestration and connectivity resilience together
Through the CSL IoTM Platform, organisations can manage supported operator profiles and coordinate planned connectivity changes across their estate. rSIM® complements this central orchestration by responding locally during a connectivity failure, without relying on the platform to reach the device at that moment.
Together, SGP.32 and rSIM therefore support planned change across the device lifecycle and local resilience during a connectivity incident:
| Lifecycle management through SGP.32 | Local resilience through rSIM | |
|---|---|---|
| Role within the model | Manages which operator profiles are available on a device and supports planned profile changes | Selects an alternative connectivity profile when the active path meets a configured failure condition |
| When it is used | Throughout the device lifecycle, including localisation or a planned move to another operator | During a live connectivity incident |
| Where it operates | Through remote management systems and supported components on the device | Locally on the SIM |
| What it contributes | Flexibility to manage and change connectivity over the life of the device | A local response when the active path fails and an independent alternative remains available |
To provide this local resilience, rSIM® combines two independent multi-network roaming profiles with SIM-resident switching logic. When the active connectivity path meets a configured failure condition, rSIM can select the alternative profile without an instruction from the remote platform. The profiles use CSL’s DualCore® architecture, providing independent mobile-core paths designed to avoid reliance on a single shared mobile core. This local switching capability complements remote connectivity management, strengthening network-path resilience within a wider service design that also accounts for device equipment, power and destination systems.

Turning orchestration into an operational service
Supporting these connectivity capabilities in practice also requires clear operational ownership. Defined support processes and a record of profile and subscription actions help teams track changes, identify exceptions and coordinate their resolution.
This operational focus is particularly important in the critical applications CSL serves, where a loss of data, voice services or signalling can have business, operational or regulatory consequences. CSL’s managed connectivity services include private APN and VPN connectivity to alarm receiving centres across Europe supporting life- and security-critical services.
Considerations for a mixed IoT estate
Every IoT estate has its own combination of operators, platforms, devices and commercial arrangements. Moving towards a more unified model therefore starts with understanding the existing environment and identifying which elements should be brought together.
From there, the transition can be phased around active services, existing contracts and the operational requirements of different devices and markets.
Frequently asked questions
How do you manage IoT connectivity across multiple mobile operators?
CSL’s connectivity management capabilities help organisations manage services across supported mobile operators. The CSL IoTM Platform brings physical SIM and eSIM subscriptions, inventory, connectivity status and rate plans into one interface across its supported integrations.
Can we keep our existing operator contracts?
Yes. Customers can retain their existing operator contracts and use the CSL IoTM Platform to manage the associated connectivity across supported operators and integrations. CSL can map the existing operator environment against the platform’s available integrations.
How do SGP.32 and rSIM work together?
SGP.32 supports remote eSIM profile management, while rSIM adds a local response during a connectivity failure. Together, they combine lifecycle flexibility with SIM-level resilience.
Can connectivity management be brought together in phases?
A phased transition may be possible, depending on the operators, platforms and active devices already in use. CSL can assess the existing estate and identify where a more consistent management approach can be introduced first.
