CSL Group is buying IoTM Solutions to consolidate multi-carrier SIM and eSIM management for enterprise IoT estates.
IoTM Solutions is a cloud-native connectivity management vendor whose platform unifies SIM lifecycle operations, eSIM profile handling, usage reporting, support workflows, and API access across multiple operators. Financial terms of the deal remain undisclosed.
Dan Amir, CEO and Co-Founder of IoTM Solutions, said: “IoTM was created to remove the complexity of managing IoT connectivity across multiple operators, platforms, and countries. Joining CSL Group allows us to bring that capability to a larger global customer base, supported by CSL’s managed connectivity services and rSIM resilience.
“Together, we can help customers and mobile operators simplify SIM and eSIM operations and prepare for the next generation of global IoT.”
The acquisition expands CSL’s managed IoT connectivity and patented rSIM resilience services by adding a single operating layer that spans legacy estates and new deployments regardless of underlying Connectivity Management Platform (CMP) or carrier systems.
IoTM Solutions, founded in 2015, reports that its platform already manages more than 30 million SIMs and holds capacity to onboard over a billion. Company statements claim more than 20 native CMP, API and carrier platform integrations plus reach to more than 100 mobile operators.
Customers access the estate through one managed service rather than separate portals for each carrier or CMP. Provisioning of an entire SIM fleet, according to IoTM descriptions, completes in hours rather than days. The team will join CSL while existing customer, operator, and service-provider contracts continue under the same platform.
CSL currently manages more than three million connections across building security, healthcare, infrastructure, utilities, and transport. Its Critical Connectivity and rSIM offerings focus on multi-path, always-available designs for applications where network outages carry high operational cost.
Combining the two portfolios lets enterprises treat carrier failures, permanent roaming prohibitions, regulatory shifts and local market changes as configuration tasks inside one system instead of separate service tickets. rSIM handles radio-level failover at the SIM itself; the IoTM layer manages the administrative and lifecycle controls above it.
Unifying fragmented carrier and eSIM operations
Enterprises running global IoT fleets routinely confront separate portals for each mobile network operator, successive generations of CMP software, and distinct eSIM profile ecosystems. Each additional country or operator multiplies authentication models, reporting formats, support channels and billing feeds.
Permanent roaming restrictions now force periodic profile swaps or local-operator insertions in multiple jurisdictions. Service restoration after an outage often requires concurrent tickets into several carrier systems. The resulting operational load delays device activation, slows compliance adjustments, and increases the chance of configuration drift.
IoTM’s vendor-agnostic approach absorbs those heterogeneous back ends. Operators continue to run their own systems while the management plane presents a common control layer for provisioning, state changes, quota enforcement, and diagnostic queries. Device fleets can permanently roam until a regulation changes, then receive a new local profile without re-imaging RMs or rewriting application logic.
The architecture relies on pre-built adapters; expansion to a new carrier therefore becomes an integration configuration rather than a full development project. CSL customers already using rSIM gain the ability to couple SIM-level path resilience with higher-layer profile orchestration, reducing the window in which an outage or regulatory block leaves devices unreachable.
Production environments impose constraints that press-release metrics alone cannot remove. SIM databases often contain incomplete or inconsistent international mobile subscriber identity records. Carrier APIs differ on rate limits, authentication schemes, and error semantics. Real-time usage telemetry from one operator arrives late or incomplete relative to another. Integration teams must therefore model reconciliation rules, buffering strategies, and fallback behaviours before cutting over live fleets.
SGP.32 transition and operational control
GSMA’s SGP.32 specification redefines remote eSIM provisioning for IoT by introducing a simpler architecture optimised for large device populations and automated lifecycle events.
Enterprises migrating from earlier eSIM standards or from physical SIM only stacks face profile calendar synchronisation, bootstrap profile substitution, subscription management server orchestrations, and reverse logistics for devices that cannot receive over-the-air updates. Permanent roaming evolution accelerates the need for programmable local profiles that can be loaded, paused, resumed, or deleted without physical intervention.
The combined CSL-IoTM stack positions itself as the operational layer that sits above the raw SGP.32 interfaces. Customers feed device inventory, policy rules, and commercial constraints into the higher management plane; the plane then drives profile staging, download triggers, state checks, and exception handling across multiple operators.
This design avoids locking an entire estate to a single carrier’s SGP.32 implementation. It also separates radio resilience (rSIM) from administrative resilience, so a profile-management outage need not drop the underlying data path and a radio path failure need not strand the management channel.
Realistic cut-over programmes still require phased work. Inventory clean-up, dual-write validation periods, rollback procedures for failed profile installs, and parallel running of legacy CMP tools form the practical sequence.
Enterprises that operate under sector-specific mandates should verify that the unified platform preserves the same certification status as their previous silos. Latency budgets, message throughput ceilings, and support-response SLAs must be re-baselined against mixed-carrier traffic rather than ideal single-operator test conditions.
Ed Heale, CEO of CSL Group, commented: “SGP.32 marks the biggest change in IoT connectivity management since the introduction of eSIM. Customers won’t simply need a new standard; they’ll need a new operating model.
“Bringing IoTM Solutions into CSL Group allows us to deliver that; combining IoT connectivity management, eSIM orchestration, and resilient connectivity into a single service that prepares customers for the next generation of global IoT.”
All scale figures – 30 million active SIMs, billion-SIM capacity, three million existing CSL connections – originate from the respective companies. Independent verification of concurrent load, concurrent profile change rates or multi-operator failure scenarios under production chaos remains unavailable in the announcement.
Any organisation evaluating the combined offering should run their own marketplace scenarios against live device fleets, measuring provisioning time under partial network blackouts, regulatory profile-exchange windows, and concurrent support-query volume.
