For years, “Day 1” meant the adrenaline of launch: ship the thing, connect the thing, prove it works. The phrase was popularised in tech culture as a warning against complacency—because “Day 2” is where complexity, slow decisions and operational drift start to pile up.
Now that mindset is colliding with a new reality: enterprises are transitioning IoT assets through faster automation, fewer breakpoints across rollouts or expansion, and far less tolerance for downtime or uncertainty. The difference between a successful pilot and a scaled deployment is rarely limited to hardware. It is the operational control plane: how you provision, govern, verify and optimise connectivity—repeatedly, across years, connectivity transitions involving multiple carriers and geographies.
Many organisations began their IoT journeys with traditional SIMs that will persist; many others may have prior eSIM under the M2M standard (SGP.02) for industrial IoT. Increasingly, they are adding GSMA SGP.32-based IoT eSIM capabilities to support what scaled operations actually demand: simpler, secure profile management for large fleets via an eSIM IoT Manager (eIM), interoperability with SM-DP+ infrastructure, and the ability to keep devices connected as they enter new markets or shift between public and private network environments, or across multiple contract cycles.
A key shift in SGP.32 is the introduction of connectivity state management via eIM for simpler profile management — designed for “headless” fleet devices that need to validate readiness and continuity as profiles and networks evolve. Kigen’s SAS-certified eIM takes the basic compliance further with optional features such as indirect profile download. Think about the time when devices may be air-gapped, and you need certainty if they are on the right network, using the right profile. This store-and-deliver function enables greater readiness in make-or-break moments during a planned roll-out.
Enterprises care about two things when making this transition:
A) avoiding any shock loss of connectivity, and B) avoiding a shock in cost—so the best available carrier connectivity is used at the right price. This is where orchestration matters.
Simetric’s cross-carrier Single Pane of Glass (SPoG) platform is built to unify device visibility, provide normalised workflow, and policy execution across carriers and platforms, helping teams keep operations consistent and devices fully productive far beyond merely optimising their connectivity.
When combined with Kigen’s SGP.32 eSIMs, profile management via its SAS-certified eIM, and Kigen In-Factory Profile Provisioning (IFPP), enterprises can address common Day 1 pitfalls before they become Day 2 failures: secure, repeatable factory-to-field provisioning that reduces SKU sprawl and avoids redesign cycles; improved reliability and “canarying” to validate deployments early; and cleaner continuity when eSIMs are introduced into fleets that already sit under legacy carrier arrangements.
Critically, integrating these layers helps prevent operational mismatches—like a device showing Profile A while being billed for Profile B (or both). Instead, devices operate to business policy and an optimised data package, with fewer blind spots across the stack.
Further, enterprises now operating IoT in the world’s largest markets need to factor in regulatory-compliant cybersecurity operations that put the eSIM at the heart of security patching. Such operations may necessitate movement across carriers. For connectivity providers themselves, supporting such integrations is an opportunity to extend the connectivity customer base, even when device roles change.
We unlock the true potential of real-time automation secured by IoT by making these operational transitions simpler for enterprises.
Leading integrators pave the way
This integrated approach is already being validated with brands, including Itron and Digi—bringing practical proof points for enterprises planning “Day 2” from the start.
Itron
“Itron is helping utilities move into a new phase of connected metering – one focused on lifecycle longevity, operational efficiency, and the flexibility to adapt as networks evolve. By leveraging SGP.32 eSIM technology from Kigen, Itron simplifies manufacturing, enables remote lifecycle management, and supports resilient multi-network connectivity that extends the life of field devices while reducing operational overhead. As deployments scale across distributed environments, Simetric’s orchestration control plane brings the operational visibility and repeatable workflows needed to coordinate devices, carriers and geographies. Together, this approach allows Itron to deploy faster, operate at scale, and maintain control across decades-long infrastructure investments without adding complexity.”
Digi International
“Digi is helping organisations simplify distributed networking at the edge — delivering true operability across network providers, reliable global connectivity, and greater flexibility from manufacturing through deployment. Through SGP.32 eSIM technology from Kigen, Digi enables adaptable, standards-based connectivity that allows edge routers to operate seamlessly across regions and carriers. As distributed environments scale, Simetric’s orchestration control plane brings operational visibility and lifecycle coordination across devices and networks, ensuring deployments remain manageable long after installation. The result is a validated approach that gives Digi’s edge routing customers the flexibility of eSIM with the operational stability required to succeed in distributed networking environments.”
What next?
Day 2 success is earned before the first device ships. Enterprises that engage early—aligning product, procurement, connectivity, and operations around SGP.32-ready architecture—can avoid costly rework, protect uptime, and ensure connectivity stays optimised as fleets expand into new markets and network models. If you are planning your next scaled deployment, now is the moment to define the operating decisions that will compound into lasting advantage.
