Overcoming the limits of standard cellular connectivity

Deploying large-scale sensor networks often faces two critical hurdles: excessive battery consumption and poor signal penetration in underground or industrial environments. Using a standard 4G multi-operator SIM for devices that only need to send small packets of data leads to unnecessary costs and frequent maintenance visits to replace batteries.

iot.cards provides a specialized nb-iot sim card solution designed specifically for LPWAN (Low Power Wide Area Network) applications. Our connectivity allows your hardware to stay in the field for years, maintaining a reliable link even from deep indoor locations or remote agricultural areas, all without the need for manual network switching thanks to our automated global roaming.

Technical Advantages for Scalable IoT

Battery Optimization

Full support for PSM (Power Saving Mode) and eDRX features to maximize device lifespan up to 10 years in the field.

Deep Indoor Coverage

NB-IoT provides an extra 20dB gain compared to standard cellular, reaching meters underground and through thick concrete walls.

Secure Infrastructure

Protect your data using a private APN, ensuring your sensors never touch the public internet.

Global Use Cases for LPWAN Technology

Our connectivity is powering projects in over 180 countries. From smart metering solutions for water and gas utilities to environmental sensors in precision agriculture, the stability of NB-IoT ensures data arrives on time, every time.

Whether you are managing a fleet of smart bins or monitoring structural integrity in bridges, our platform provides real-time visibility and control. All SIMs are managed from a single portal, allowing you to monitor consumption, set alerts, and activate thousands of lines in seconds with no minimum permanence or hidden fees.

Common questions about NB-IoT

Does it support global roaming?

Yes. Our NB-IoT SIM cards are multi-carrier and support automatic roaming in over 180 countries, ensuring coverage across different regional operators without hardware changes.

Can I manage thousands of SIMs programmatically?

Absolutely. We provide a robust management API that allows you to integrate SIM activation and status monitoring directly into your own ERP or dashboard.

Is secure remote access possible?

Yes. While we do not offer public fixed IPs for security reasons, we provide private APN and VPN tunnels for secure bi-directional communication with your devices.
