Solving the connectivity gap in utility and energy monitoring
Energy management systems depend on the constant flow of data from smart meters to central servers. However, deploying thousands of devices in basements or remote locations often leads to intermittent connectivity when using standard mobile networks. Our multi-operator IoT SIM cards ensure your devices stay online by automatically switching to the strongest available signal.
iot.cards provides the industrial-grade infrastructure needed to scale your metering network globally. With roaming in 180+ countries and support for low-power technologies, we eliminate the operational headache of managing multiple local contracts and technical incompatibilities across different regions.
Technical features for advanced metering infrastructure
NB-IoT & LTE-M Support
Optimized for low-power consumption and deep indoor penetration, ideal for gas and water meters located in basements.
Industrial Form Factors
Available in standard 2FF/3FF/4FF sizes or embedded MFF2 industrial chips for harsh environments.
Permanent Roaming
Avoid device disconnection due to roaming restrictions. Our global agreements guarantee permanent connectivity everywhere.
Global Reliability for Energy Management Systems
Whether you are managing residential smart meters, solar panel monitoring systems, or industrial energy sub-metering, data integrity is paramount. Our connectivity solutions for smart metering are designed to provide the high availability required for real-time grid balancing and precise billing.
Our SIM cards arrive pre-activated and ready for deployment. Once installed, technical teams can monitor data consumption, troubleshoot signal issues, and manage lifecycles through our centralized management portal, ensuring operational efficiency from day one.

Frequently Asked Questions
What is the best technology for smart metering?
NB-IoT and LTE-M are generally preferred for metering due to their excellent building penetration and low power consumption, allowing for long battery life in gas and water meters.
How do you ensure data security?
We use Private APNs and VPN tunnels to route data directly to your cloud without exposing devices to the public internet. This prevents unauthorized access to the energy grid data.
Can I manage thousands of SIMs at once?
Yes, our platform is built for scale. You can group SIMs, set usage alerts, and perform bulk actions via our portal or integrate directly using our powerful API.
