NTT DOCOMO BUSINESS and Saudi Arabia’s stc group have launched an IoT connectivity solution for Komatsu construction equipment operating in the Kingdom, giving the Japanese manufacturer a locally compliant way to keep machines connected without having to rebuild its global connectivity model on a country-by-country basis.

At first glance, this is a relatively narrow industrial IoT announcement. In practice, it illustrates one of the most important changes underway in enterprise connectivity: “global” no longer necessarily means keeping every device permanently roaming on a foreign SIM.

What actually changed

Komatsu uses its Komtrax telematics platform to collect operating data from construction equipment for remote monitoring, analytics and predictive maintenance. For that system to work reliably in Saudi Arabia, the machines need persistent cellular connectivity that fits local telecommunications requirements.

Under the new arrangement, NTT DOCOMO BUSINESS is responsible for solution design, implementation and ongoing support. stc provides the local connectivity layer, including SIMs, its mobile network and a Connectivity Management Platform.

That division of responsibilities matters. Komatsu can continue dealing with a global connectivity partner while the actual Saudi connection is delivered locally.

NTT says the solution is designed around three capabilities:

• in-country connectivity aligned with Saudi telecommunications requirements;
• connectivity and centralized management using stc’s network and CMP;
• end-to-end support from design through implementation and operation.

The result is less about giving a bulldozer “mobile data” and more about making connectivity part of the machinery’s operating architecture.

Global connectivity is becoming local

For manufacturers shipping connected products worldwide, traditional roaming has an obvious attraction: one connectivity arrangement, one SIM strategy and fewer country-specific integrations.

The problem is that industrial equipment does not behave like a traveler’s smartphone. A machine may remain in one country for years. That creates technical, commercial and regulatory complications in markets where permanent roaming is restricted or treated differently from ordinary consumer roaming.

NTT has been building around this problem for years. Its IoT Connect Mobile Type A platform, launched in 2022, supports centralized global connectivity management and can use partner-carrier IMSIs in markets where permanent roaming creates difficulties.

But NTT does not say that this exact multi-IMSI configuration is being used for Komatsu in Saudi Arabia. The new announcement instead specifically describes local stc SIMs and stc’s CMP.

That distinction is important.

The wider strategy is not simply “roam everywhere.” It is to give a multinational manufacturer one operational framework while allowing the underlying connectivity to become local where necessary.

Why this matters beyond construction machinery

The same problem appears in connected cars, agricultural machinery, industrial equipment, logistics assets and other products manufactured centrally but deployed for years across different regulatory environments.

This is why the competitive question in global IoT is changing.

Coverage still matters. So do roaming agreements. But the more valuable capability is increasingly the ability to manufacture once, deploy internationally and then localize connectivity without forcing the OEM to redesign hardware, renegotiate its entire connectivity stack or manage a patchwork of national contracts.

NTT is not alone in pursuing that model. BICS combines multi-IMSI technology with local profiles and remote provisioning through its eSIM Hub, specifically positioning the architecture as a way to handle permanent-roaming restrictions. Eseye similarly promotes localized eSIM and iSIM profiles alongside centralized management for global IoT deployments. 1GLOBAL uses multi-IMSI technology and can add local identities over the air so devices can behave more like local subscribers.

NTT’s differentiator in the Komatsu example is the orchestration role: pairing a global enterprise relationship with a major local operator and taking responsibility for the design-to-operation layer.

That makes the model particularly relevant to multinational OEMs. It is less compelling for small, single-country IoT deployments, where a direct local operator contract may be simpler, or for low-value devices whose economics do not justify a more heavily managed connectivity architecture.

The next competitive layer

There is still room for improvement in how these deployments are communicated. Neither NTT nor stc disclosed the number of Komatsu machines covered, commercial terms, rollout timing, service-level commitments or measurable performance improvements. Those details would help enterprise buyers judge whether the model delivers operational advantages beyond regulatory compliance.

The market is also moving quickly toward newer eSIM-based IoT architectures. BICS, Eseye, 1GLOBAL and other global connectivity providers are increasingly competing not only on coverage but on remote profile management, localization, policy control, resilience and compliance.

NTT itself is expanding that stack. Its September 2026 “Pro” plan for docomo business SIGN targets large-scale global connected products, while its earlier partnership with Airlinq was explicitly designed to extend IoT deployments into regulated markets.

Conclusion: the global SIM is becoming a control layer

The Komatsu deployment is interesting because the SIM itself is almost beside the point.

The real product is orchestration.

Global manufacturers increasingly need one commercial and operational framework that can decide when roaming is sufficient, when connectivity needs to be localized, which operator should serve the device and how thousands of connections are managed without creating a separate telecom project in every country.

That is where NTT, BICS, Eseye, 1GLOBAL and similar players are converging, even if their technical approaches differ.

The next phase of global IoT will therefore be less about who can claim the longest country list and more about who can make a globally manufactured product connect as if it were local—without making the manufacturer manage the complexity behind it.

Saudi Arabia and Komatsu provide a useful real-world example of that shift.
