Solve Networks is taking a connectivity model forged in oilfields and industrial sites and pushing it across borders.

The Texas-based provider has launched global eSIM connectivity for enterprise IoT deployments whose devices move between countries, carriers and operating regions. The pitch is simple: instead of managing local SIMs and carrier contracts, customers can use a single downloadable profile and manage those connections through Solve’s existing Clarity platform.

According to the company’s September 9 announcement, the new eSIM connects across networks in more than 200 countries and territories across the Americas, Europe, Africa, the Middle East and Asia-Pacific. It is available now to new and existing customers.

That sounds straightforward. In industrial IoT, though, “global” rarely is.

From oilfields to cross-border fleets

Solve has built much of its identity around places where connectivity failure has consequences. Its oil and gas offering supports SCADA systems, remote monitoring and field equipment using private static IPs, VPNs and multi-network connectivity. The company also combines cellular with LEO satellite connectivity where terrestrial coverage disappears entirely.

That background matters. A travel eSIM can tolerate an awkward reconnection. A remote pipeline sensor, industrial controller or moving logistics asset may not.

Solve says its global eSIM extends the same approach to manufacturing, logistics, fleet and energy deployments operating across multiple regions. Customers can activate, switch or re-provision profiles digitally, reducing physical SIM swaps and costly field visits.

Clarity is important here. Solve already uses the platform to activate SIMs, monitor usage and uptime, and manage domestic multi-network deployments. Adding international eSIM connectivity to the same environment avoids one of enterprise IoT’s quieter problems: another portal, another contract and another workflow.

The market has moved

Solve is not entering an empty category. Quite the opposite.

KORE’s Super SIM promises access to hundreds of networks across more than 180 countries through one global SIM and platform. Wireless Logic says its Conexa network reaches more than 750 networks in 190 countries. Eseye’s AnyNet proposition spans more than 800 networks in 190-plus countries, combining roaming, localisation and eUICC-based switching.

Those numbers should not be read like consumer coverage maps. More networks do not automatically mean better service. The harder questions are which networks are available in each country, whether connectivity is roaming or localised, how failover behaves, which radio technologies are supported, and what happens when regulatory conditions change.

This is where Solve still has some explaining to do publicly. Its launch announcement cites 200-plus countries and territories, while its current Global SIM page says 250-plus countries. Enterprise buyers would benefit from a detailed coverage matrix showing operators, network technologies, permanent-roaming status, localisation options and country-specific restrictions. “Global” is useful shorthand; procurement teams need the footnotes.

eSIM is becoming infrastructure

The timing is interesting because industrial eSIM is moving beyond the old “no physical SIM swap” story.

In May, the GSMA published SGP.32 v1.3, its latest technical specification for remote provisioning and management of eSIMs in IoT devices, including constrained devices with little or no user interface. It pushes IoT connectivity toward software-controlled lifecycle management rather than a SIM decision made once at manufacturing.

The ecosystem is already moving. emnify introduced an SGP.32 connectivity model this year built around factory provisioning, provider independence and fallback. Kigen is testing SGP.32 deployments with multiple connectivity partners, while GSMA’s 2026 eSIM discussions increasingly focus on scalability, interoperability and lifecycle control.

Solve’s announcement does not state that its new global eSIM is based on SGP.32, so it would be wrong to assume that. Still, the direction is similar: fewer physical interventions, fewer carrier-specific silos and more ability to change connectivity after a device has shipped.

That is useful for OEMs producing one hardware SKU for multiple markets, logistics companies with assets crossing borders, and industrial operators that cannot predict where a device will spend the next decade.

It is less compelling for a small, fixed deployment that already has reliable local connectivity and no realistic need to change providers. There, a conventional operator agreement may remain cheaper and simpler.

Reliability is the actual product

Stephen Mammen, Solve Networks’ VP of Engineering, makes a sensible point in the launch: global eSIM is not a one-size-fits-all answer. That is more credible than pretending every enterprise fleet suddenly needs eSIM.

The strongest part of Solve’s positioning is therefore not the eSIM itself. It is the attempt to package global connectivity around industrial expectations: security, multi-network resilience, central management and human support.

Solve also claims near-100% customer retention. That is a strong number, although it is company-reported and would be more useful with a defined period and customer base behind it.

For buyers comparing vendors, that service layer may become the real differentiator. KORE brings global scale and orchestration. Wireless Logic has a broad network footprint and mature connectivity management. Eseye pushes deeply into localisation and automated switching. emnify is leaning into cloud-native and SGP.32-era programmability. Solve’s opportunity is to be the specialist that understands what happens when an IoT device is not merely connected, but operationally critical.

Conclusion

The enterprise eSIM market is shifting from “can this device connect abroad?” to “can we control connectivity for the entire life of the device?”

Solve Networks fits that shift well. Its industrial heritage gives the global eSIM offer more credibility than a generic global-SIM launch, particularly for energy, manufacturing and remote infrastructure. But the next step should be greater transparency: exact network availability, localisation strategy, standards support and regulatory handling will matter more than another impressive country count.

The winners in industrial eSIM will not be the providers with the longest coverage list. They will be the ones that make carrier complexity disappear without making enterprise control disappear with it. Solve has entered that race with a proposition that makes sense. Now it has to prove, country by country and deployment by deployment, how industrial-grade “global” really is.
