Reliable cellular connectivity for your IoT deployments in Brazil
Deploying IoT devices across Brazil — from agribusiness telemetry in Mato Grosso and fleet tracking on the Sao Paulo-Santos corridor to utility metering and POS terminals — demands connectivity that never becomes the single point of failure. Our multi-operator SIM cards connect to Vivo, Claro and TIM via data roaming and switch automatically to the strongest available network.
At iot.cards we are honest about the regulatory side: Anatel limits permanent IoT roaming in Brazil (rough tolerance is 90 continuous days), so the roaming SIM is the right tool for pilots, trials and assets in transit — and for permanent fleets we provision compliant local connectivity via eSIM (eUICC) with a Brazilian profile. Managed from one platform, billed in euros, no long-term contracts.
Enterprise-Grade M2M Technical Specifications
Multi-Network Redundancy
Our SIMs connect to Vivo, Claro and TIM. This ensures maximum uptime for critical devices across Brazil's vast territory, with automatic switching when a network degrades.
Anatel-Compliant Route
Roaming for pilots and assets in transit; for permanent fleets we provision an eSIM (eUICC) local Brazilian profile on the same hardware. We tell you the compliant route before you buy.
Secure Private APN
Secure your fleet or infrastructure with a Private APN and IPSec/WireGuard tunnels. A closed network environment, with no exposure to the public internet.
Powering Brazil's agribusiness, logistics and utility deployments
Brazil concentrates enormous IoT demand: precision-agriculture sensors and machinery telemetry in the Cerrado, cold-chain and fleet tracking on the export corridors, water and energy metering, solar-plant monitoring and POS terminals nationwide. Our SIMs provide the 4G LTE and NB-IoT connectivity these deployments require, with precision-agriculture solutions and logistics solutions that keep assets connected from the port to the interior.
Every deployment is managed via our centralized portal: monitor consumption, activate or pause SIMs instantly, and integrate with your ERP through our REST API. Coverage details at our Brazil coverage page.
Frequently Asked Questions
Which networks do the IoT SIMs use in Brazil?
The three national networks: Vivo (Telefonica Brasil), Claro and TIM. The SIM is non-steered and connects to whichever network provides the best signal at your specific location, switching automatically if coverage degrades.
Is permanent roaming allowed in Brazil?
Not indefinitely. Anatel limits permanent IoT roaming: the rough tolerance is 90 continuous days, beyond which traffic may be cut by the visited operator. A roaming SIM is right for pilots, trials and assets in transit; devices operating permanently in Brazil need a local SIM or an eUICC eSIM with a Brazilian profile downloaded in-country. We review your exact case during onboarding and tell you the compliant route before you buy — see our permanent roaming guide.
Do you support NB-IoT in Brazil?
Our cards support NB-IoT where local carriers have deployed it, alongside 4G LTE for higher-bandwidth applications. LPWAN availability varies by operator and area — validate coverage per site during your pilot with the SIM Test Kit.
