Eliminating Data Gaps in Temperature-Sensitive Logistics
Maintaining the integrity of the cold chain requires more than just high-quality sensors; it demands unbreakable connectivity. A single blind spot during transit can lead to compromised pharmaceuticals or spoiled food products, resulting in massive financial losses and regulatory non-compliance. Standard SIM cards often fail when crossing borders or entering remote regions where a single carrier's signal drops. Our logistics connectivity solutions are engineered to prevent these outages by providing seamless network switching.
iot.cards provides specialized IoT SIM cards designed for global cold chain temperature sensors, offering multi-carrier redundancy in over 180 countries. With permanent roaming capabilities and no lock-in contracts, your monitoring devices stay connected to the strongest available signal, ensuring that critical temperature and humidity data reaches your dashboard in real-time, regardless of the shipment's location.
Connectivity Built for Thermal Reliability
Multi-Operator Roaming
Our multi-operator SIM cards connect to the best available 4G, LTE-M, or NB-IoT network, ensuring continuous data transmission during international transit.
Industrial Durability
Available in standard plastic or MFF2 embedded formats, our SIMs are built to withstand the extreme temperature fluctuations typical of refrigerated transport and storage.
Remote Management
Monitor consumption, activate or suspend lines, and set automated alerts via our centralized platform or direct API integration for large-scale deployments.
Global Visibility for Cold Chain Logistics
From pharmaceutical distribution to the transport of perishable food, maintaining a precise temperature range is non-negotiable. Our IoT SIM cards empower sensors to report telemetry data even in high-speed transport or cross-border routes. With support for NB-IoT and LTE-M, your devices benefit from deep indoor penetration, perfect for sensors located inside thick-walled refrigerated containers or warehouse basements.
Managing a fleet of thousands of sensors is simplified through our management portal. You can track data usage in real-time and ensure every device is operational before it leaves the dock. Activate your SIMs in 24 hours and benefit from a scalable model that grows with your fleet without hidden costs or long-term permanence.

Common Questions
Is my data secure during transmission?
Yes. We offer Private APN solutions that keep your sensor data off the public internet, routing it directly to your servers via a secure tunnel.
Will these SIMs work inside a refrigerated truck?
Our SIMs support LTE-M and NB-IoT, which offer superior signal penetration compared to standard 4G, making them ideal for devices shielded by metal walls or insulation.
Do you offer eSIM formats for cold chain sensors?
Yes, we provide eSIM for IoT, which is highly resistant to vibration and extreme environmental stress, perfect for permanent integration into sensor hardware.
