CSL Group acquires IoTM Solutions to scale eSIM orchestration
CSL Group, the London-headquartered managed IoT connectivity provider, has acquired IoTM Solutions Ltd in a deal aimed at building a unified platform for global SIM and eSIM lifecycle management. Financial terms were not disclosed.
IoTM, founded in 2015, operates a cloud-native connectivity management platform that aggregates fragmented carrier systems, connectivity management platforms (CMPs) and eSIM workflows into a single managed service. At the time of the acquisition the platform manages more than 30 million SIMs, supports 20-plus native CMP and carrier integrations, and provides access to more than 100 mobile operators. CSL says the platform's design means customers can provision their entire SIM estate in hours rather than days.
The deal
The acquisition extends CSL beyond pure-play connectivity into SIM and eSIM orchestration, filling a gap the company identifies as a growing pain point for enterprise IoT operators. Fragmented carrier portals and separate management platforms add operational friction, slow carrier onboarding and complicate compliance with permanent roaming restrictions that several jurisdictions, including the UK and EU markets, have tightened over recent years.
CSL chief executive Ed Heale said the transition to SGP.32, the GSMA's next-generation eSIM architecture for IoT, represented "the biggest change in IoT connectivity management since the introduction of eSIM," adding that customers would need a new operating model rather than simply a new standard. The IoTM team will continue supporting existing customers, operators and service provider partners under the combined group.
Dan Amir, chief executive and co-founder of IoTM Solutions, said the acquisition would bring the platform's capabilities to "a larger global customer base, supported by CSL's managed connectivity services and rSIM resilience."
Market context
The IoT connectivity management market is consolidating around a small number of vendors that can offer multi-carrier orchestration alongside embedded SIM management. Hyperscalers including AWS and Azure offer IoT connectivity services, but purpose-built CMP specialists such as Eseye, Transatel (now part of NTT) and Tele2 IoT compete directly in the managed multi-operator segment. The ability to handle SGP.32 at scale is becoming a differentiator as device makers and enterprise IoT operators prepare for the standard's commercial rollout, which the GSMA expects to accelerate through 2026 and 2027.
Permanent roaming restrictions remain a live regulatory variable. Several European regulators have signalled stricter enforcement, pushing enterprises to move from traditional roaming SIMs toward local-breakout eSIM solutions that SGP.32 is designed to enable. For CSL, whose existing rSIM technology provides SIM-level network failover, the IoTM platform adds the orchestration layer needed to automate profile switching across carriers in response to both outages and regulatory change.
CSL's core verticals, including building security, healthcare, utilities and transport, carry particularly high uptime requirements, which means the resilience argument for a unified SIM management layer is commercially straightforward. The combined entity will need to demonstrate that integration does not introduce its own complexity during the transition period before SGP.32 becomes the dominant provisioning model.
The deal gives CSL immediate access to IoTM's carrier relationships and its claimed capacity to onboard up to one billion SIMs, a figure the company has not independently benchmarked. Investors and enterprise customers will be watching for named customer wins and published migration case studies as the earliest indicators of commercial traction post-acquisition.
