CSL Group is buying IoTM Solutions to consolidate multi-carrier SIM and eSIM management for enterprise IoT deployments.
Ed Heale, CEO of CSL Group, said SGP.32 is the biggest change in IoT connectivity management since eSIM, and that customers will need a new operating model rather than just a new standard. He said the acquisition will let CSL combine IoT connectivity management, eSIM orchestration, and resilient connectivity into a single service.
IoTM brings scale, integrations, and one managed service
IoTM Solutions was founded in 2015. The company says its platform manages more than 30 million SIMs and can scale to more than one billion, with more than 20 native CMP, API, and carrier platform integrations and reach to more than 100 mobile operators.
IoTM says customers can access the estate through one managed service instead of separate portals for each carrier or CMP, and that provisioning an entire SIM fleet takes hours rather than days.
CSL is folding the team into its existing connectivity stack
The IoTM team will join CSL Group, and existing customer, operator, and service-provider contracts will continue under the same platform. CSL currently manages more than three million connections across building security, healthcare, infrastructure, utilities, and transport.
CSL’s Critical Connectivity and rSIM offerings focus on multi-path, always-available designs for applications where network outages carry high operational cost. rSIM handles radio-level failover at the SIM itself, while the IoTM layer manages administrative and lifecycle controls above it.
Read for enterprise IoT operators
The acquisition points to a single control layer for multi-carrier SIM and eSIM estates, rather than separate portals and service flows. For operators running large IoT fleets, the relevant detail is the promised shift from fragmented carrier management to one managed service, with existing contracts staying in place.
