Multi-IMSI
Intelligence

Choose the configuration that fits. UltimateSIM integrates eUICC and Multi-IMSI technology to provide a level of resilience a single carrier cannot match. By hosting multiple network identities on one chip, devices autonomously switch based on signal quality or cost—delivering absolute uptime over-the-air.

Examples

From mission-critical uptime to cost-efficient mass deployments, explore how we architect our multi-IMSI technology to meet the specific technical and commercial requirements of your IoT devices.

“The market is moving towards eSIMs. Likewise, Velos IoT is also incorporating eSIMs and were very proactive in their communication to us. We will receive one shortly to start testing and we feel confident that with both our hardware partner and Velos IoT, we will be able to integrate this smoothly into our system.”

Jan Broux, Product Manager

“Technology is the most important thing that attracts us. Now our support operation runs in “proactive” mode, we can predict when consumers are due to top-up and ensure that we have established connectivity to deliver the tokens. Our meter operators can instruct our meters to roam on certain networks that we know perform better in certain areas and weather conditions. We’ve taken this a step further integrate MeterPay with Velos IoT through Nomad’s API functions into MeterPay so our SIMs are activated during our smart meter dispatch warehousing process.”

Expert Insights & Technical Support

Connectivity shouldn’t be a black box. Find clear, direct answers to the most common questions about deploying, managing, and scaling your global IoT estate with UltimateSIM and Nomad.

UltimateSIM utilizes advanced eUICC and Multi-IMSI technology to provide a level of resilience a single carrier cannot match. By hosting multiple network identities on a single chip, devices gain the autonomous intelligence to switch networks based on signal quality or location—ensuring continuous uptime across 700+ direct MNO agreements.

UltimateSIM is a single, global SKU designed to support the full evolution of IoT, including 5G, LPWA (NB-IoT/LTE-M), and SGP.32-ready eSIM standards. This allows for zero-touch global deployment, enabling you to localize connectivity remotely and dynamically without the need for physical SIM swaps.

Security is built into the architecture, protecting the entire data journey from the device to the cloud. Beyond standard connectivity, UltimateSIM supports hardened security features such as private APNs, fixed IPs, and IMEI locking through the Watchdog policy engine to prevent unauthorized device usage.

Yes. UltimateSIM operates as a dynamic, policy-driven service rather than a static data plan. Through the Nomad platform, you can define business rules—such as roaming controls, cost thresholds, or performance targets—and the SIM will automatically enforce those network selections at scale.

Nomad serves as a single pane of glass that replaces fragmented operator portals and manual spreadsheets with a unified interface. It simplifies global operations by consolidating connectivity into one platform, providing automated cost controls and unified invoicing to ensure predictable performance and eliminate “bill shock”.

Smart HVAC Systems: How IoT Cuts Energy Costs and Downtime

A smart HVAC system is a heating, ventilation and air conditioning setup with IoT sensors, distributed control boards and network connectivity built in. It lets you monitor and control temperature, humidity, airflow and energy use remotely — and flags faults before equipment fails. The main gains are lower energy bills, fewer emergency call-outs and easier regulatory reporting.

eUICC vs. eSIM: What’s the Real Difference (and Why It Matters for Your IoT Fleet)

If you’ve spent any time researching connectivity for connected devices, you’ve probably seen “eSIM” and “eUICC” used as if they mean the same thing. They don’t — and for anyone building or scaling an IoT deployment, that distinction isn’t just semantics. It affects how you provision devices, how flexible you are with carriers, and how much manual work your team ends up doing down the line. At Velos IoT, we get asked about this constantly, so let’s clear it up properly.

What are the benefits of a Fixed Private IP SIM card?

While ordinary mobile SIMs are built for one-way outbound data, an IoT SIM card with a Fixed IP opens up a continuous, two-way channel. This ensures your devices aren’t just sending data to the cloud, but are always reachable for real-time remote access, troubleshooting, and control. Static VS Dynamic IP…
