The IoT world just got a jolt of genuinely good news. NuvoLinQ, a company known for its intelligent connectivity platform, has pulled off something many in the industry quietly believed was impossible: enabling legacy and already-deployed IoT devices to run on the newest eUICC (SGP.32) standard—without replacing hardware.

For years, enterprises planning to modernize connectivity have hit the same wall. SGP.32, the next-generation eSIM specification, offers huge advantages—remote carrier switching, enhanced security, smooth provisioning, private networks, and more. But all of that power depends on one thing: the devices themselves must support it. Millions of IoT units out in the world don’t.

NuvoLinQ decided that wasn’t a good enough answer. And now, it seems, they’ve proved it doesn’t have to be.

Why SGP.32 Matters More Than Most Realize

The shift to SGP.32 is one of the biggest transitions in IoT connectivity since the introduction of eSIM itself. It’s designed to handle everything the industry has been complaining about for years: clunky provisioning, lack of scalability, carrier lock-in, fragmentation, and security limitations.

Think of SGP.32 as the “remote-first, software-defined” evolution of the eSIM ecosystem. It’s built for fleets—whether that means payment terminals, industrial sensors, smart retail systems, connected vehicles, or anything else with a modem.

But upgrading to this new world typically comes with a catch: most devices out there weren’t built for it.

NuvoLinQ went after that exact problem.

How NuvoLinQ Achieved What Others Said Would Take Years

Over several months, NuvoLinQ’s engineering team—working hand-in-hand with Kigen’s SGP.32-certified solutions—systematically tested, debugged, tweaked, and validated device behavior across different hardware classes: routers, sensors, payment terminals, edge blades… all the messy stuff you find in real enterprise deployments.

According to the company, the result is simple but remarkable: SGP.32 compatibility is possible on today’s legacy devices with no hardware modifications.

Maurizio Tersigni, NuvoLinQ’s CEO, put it plainly:

“Every device has its own quirks. We’ve spent months with pin pads, sensors, blades, and routers. Each behaves differently. Our work shows that legacy devices can indeed be brought forward into the next era of IoT.”

This leap forward comes from a mix of firmware collaboration, dynamic rescue and recovery features built into Kigen’s eSIM, and persistent device-level testing. Kigen’s CEO, Vincent Korstanje, echoed the same message:

“Dynamic eSIM is now essential to enterprise cybersecurity, but it can create real friction for installed devices. Together with NuvoLinQ, our IoT-ready eSIM suite removes that friction so PoS and automation customers can elevate remote fleets without retrofit or disruption.”

This is where things get interesting for businesses with thousands—or hundreds of thousands—of deployed devices.

NuvoLinQ’s New eUICC Readiness Program

To help companies transition fleets smoothly, NuvoLinQ is launching what it calls the eUICC Readiness Program, designed to evaluate and modernize existing hardware.

Device Compatibility Testing

A step-by-step assessment confirming whether a device can operate reliably under SGP.32.

Root Cause Identification

Troubleshooting firmware or SIM profile behavior that may block provisioning or carrier switching.

Validation Support

Companies get free 30-day test eSIMs to trial SGP.32 functionality in the field before making larger decisions.

NuvoLinQ’s message is clear: modernizing doesn’t have to mean scrapping hardware. And in a world where IoT upgrades can run into millions, that’s a compelling promise.

What This Means for the Broader IoT Landscape

NuvoLinQ’s breakthrough lands at a moment when the IoT ecosystem is under pressure—from rising connectivity costs to increasing cybersecurity risks to stricter lifecycle sustainability mandates. Other major players, such as Thales, Idemia, Giesecke+Devrient, and Deutsche Telekom IoT, have been pushing SGP.32-ready solutions too, but most still assume newer hardware or controlled environments.

Very few have tackled the messy reality: old devices in the field that still need to work for another five to ten years.

That’s where NuvoLinQ’s work stands out. If their approach scales, it could accelerate global SGP.32 adoption years faster than projected by analysts such as Transforma Insights and Kaleido Intelligence—both of which have highlighted the industry’s “retrofit bottleneck” as a major barrier to eSIM modernization.

At the same time, NuvoLinQ is positioning itself in a strategic sweet spot: somewhere between the big eSIM infrastructure players and the enterprise ops teams that desperately need practical, hands-on compatibility solutions. It’s not about announcing the future—it’s about making sure deployed hardware can actually join it.

In a market where connectivity standards evolve faster than hardware refresh cycles, NuvoLinQ may have just unlocked the missing bridge. And for enterprises with large IoT fleets, that bridge could be worth millions.
