The Wirnet iZeptoCell-Cellular integrates eSIM, for simpler and more flexible installations

With an open eSIM based on the SGP.32 standard, the Wirnet iZeptoCell-Cellular indoor gateway lets you select and switch telecom operators at any time, remotely. SIM fleet management becomes entirely software-based and is operated directly by Kerlink on behalf of its customers.
Wirnet iZeptoCell: the indoor Packet Forwarder gateway
Kerlink’s Wirnet iZeptoCell is the ideal indoor gateway for network densification. It is defined by three key features:
- Minimal footprint: our gateway is small, lightweight, and designed to fit into any indoor environment, including the most space-constrained settings.
- Maximum radio performance: an integrated antenna design that matches the performance of external 3dBi antennas.
- Simple, fast installation, plug-and-play: the Ethernet version connects behind any router with no complex configuration. The cellular version goes even further, becoming immediately operational with no cabling required at all.
Focus on the US market: its LTE-M compatibility makes it a particularly well-suited solution for IoT deployments across the United States.
SGP.32: the standard driving the SIM Card’s evolution toward IoT
The GSMA (GSM Association) is the international organization that brings together telecom operators and the key players of the global mobile ecosystem. It defines the technical standards that guarantee interoperability across mobile networks.
The SGP.32 standard is the latest evolution of GSMA’s remote SIM profile management standards. It was designed specifically to address the constraints of IoT and has now reached the level of maturity required for real-world deployment, which is what allowed us to bring this capability to our iZeptoCell-Cellular gateway.
The benefits of an eSIM-equipped gateway
1. An immediate reduction in installation costs
The SIM electronic component, the eUICC (embedded Universal Integrated Circuit Card) is soldered in and already in place during production.
In practice, the eUICC lets you manage telecom operator profiles just as you would with a classic SIM card, but entirely in software and remotely. The search for available profiles can be triggered in two ways: locally, by activating it directly on the gateway, or remotely, by initiating it from the management platform.
As a result, there is no longer any manual SIM card insertion required ahead of deployment. Note that any type of operator profile can be loaded:
- Physical operators (MNO – Mobile Network Operator): Orange, AT&T, Verizon…
- Virtual operators (MVNO – Mobile Virtual Network Operator): BICS, Matooma, 1nce
2. Optimized performance and costs
You can switch telecom operators at any time, remotely. Connectivity becomes a parameter you adjust to fit conditions on the ground, rather than a decision locked in at installation: adapting to a coverage issue, negotiating better pricing, or responding to a local regulatory requirement…
3. Simplified SIM fleet management
SIM card management becomes an entirely software-based operation. Whether managing 10 or several thousand gateways, profile control is centralized and requires no physical intervention.
Kerlink Operates the Fleet Management Service
Beyond the eUICC component embedded in the iZeptoCell-Cellular, the SGP.32 standard relies on a complementary software layer: the eIM (eSIM IoT Manager). This is the tool that enables remote, bulk control of profiles across an entire fleet of gateways.
With Kerlink, you don’t need to set up or manage your own eSIM management platform: we take that complexity off your hands by operating the fleet management service for you directly. In practice, this means we can add, activate, deactivate, or switch an operator profile on a single gateway or across a fleet of thousands of units, from a single interface, without ever needing to physically access the devices in the field.
To sum up: Operator flexibility, controlled costs, scalability
Beyond the technological innovation, this shift to open eSIM is a strategic choice: it is part of the broader transition toward a more flexible and higher-performing IoT ecosystem.
Designed for indoor deployments and network densification, the Wirnet iZeptoCell-Cellular now has a new asset: eSIM based on the SGP.32 standard gives you real flexibility in choosing your operator, while fleet management is controlled remotely, in just a few clicks. The result: lower connectivity costs, and the confidence to scale, in an environment that keeps changing.
