Overcoming the connectivity barrier in Latin America
Deploying IoT projects in Latin America, particularly in Brazil and Mexico, often presents significant challenges due to fragmented network coverage and strict local regulations. Standard roaming SIMs frequently fail or get blocked, leading to costly downtime for your devices. At iot.cards, we provide a robust solution through our multi-operator SIM cards, ensuring your hardware stays connected to the strongest available signal in the region.
Our technology is designed for mission-critical applications where failure is not an option. By integrating multiple local carriers into a single SIM, we eliminate the need for multiple contracts and complex logistics, providing a unified management experience with global reach across 180+ countries.
Technical Edge for Latam Deployments
eSIM & Industrial MFF2
Available in standard tri-punch or eSIM IoT formats, our hardware is built to withstand industrial environments in logistics and manufacturing.
Multi-Network Redundancy
Unsteered roaming allows devices to connect to Vivo, Claro, or TIM in Brazil, and Telcel or AT&T in Mexico, prioritizing signal quality above all.
Private APN Security
Secure your data traffic with a Private APN, ensuring end-to-end encryption and protection against public internet threats without requiring static public IPs.
Optimizing Operations in Brazil and Mexico
Whether you are managing a fleet of vehicles in São Paulo or monitoring industrial sensors in Monterrey, our logistics solutions provide the visibility you need. We support 4G LTE, LTE-M, and NB-IoT technologies to match your specific data consumption and battery life requirements.
Control your entire SIM state through our centralized management portal. Activate, deactivate, and set consumption alerts in real-time. With no permanent roaming restrictions in the Latam region, your devices stay online indefinitely, avoiding the 90-day cut-off common with consumer SIM cards.
