In the past few years, Brazil has worked hard to keep up with a rapidly growing global IoT market.

In March 2018, the Brazilian government launched a nationwide IoT plan, involving developments in robotics, 5G connectivity, and most recently a technology centre solely dedicated to expanding its IoT footprint.

This change has understandably piqued the interest of the IoT companies who want to expand their business in the 5th largest country in the world. However, their efforts are overshadowed by a roadblock - for years, Brazil has been implementing strict permanent roaming regulations for all connectivity users, consumers and IoT cases alike.

The current roaming regulations in Brazil don't allow foreign IMSIs to roam for more than 90 days. After the time limit is reached, there is a high probability that the connections will be blocked.

If you're interested in learning more about global roaming restrictions, read our recent blog post.

In the case of international transit, logistics, and fleet management the roaming restriction might not be that big of an issue. 

But the stationary IoT devices, or devices roaming longer within Brazil, require a different solution. In this case, one of 1oT’s Global eSIM profiles would be a reasonable choice.

1oT's Default Profile offers global coverage, as shown on the map.

Localised eSIM profile for Brazil

1oT M2M eUICC enables companies to avoid permanent roaming in Brazil. Customers can download and enable our localised profile in Brazil for their eSIM via 1oT Terminal.

The local profile solves permanent roaming restriction and has lower latency and extra security features for critical deployments. The latter is essential for official tenders, where technical specifications require a local data breakout. 1oT can also support with virtual private networks (VPNs) and extra layers of security.

Getting started with 1oT eSIM

When starting with a 1oT eSIM, our Sales and Engineering teams help customers navigate the eUICC testing phase and hardware (cellular module) compatibility checks. It's important to note that not all cellular modules support over-the-air provisioning capabilities. However, the newer LTE modules have the needed functionality.

Here is a list of 1oT in-house tested modules.

After a successful testing phase, our Customer Success and/or Account Management team will be supporting the larger-scale manufacturing, deployment and after-service.

Customers can manage and monitor their eUICC connections via the 1oT proprietary connectivity management platform (CMP) called 1oT Terminal. It's a powerful yet user-friendly self-service platform with rich functionality, especially in automating SIM-related tasks.

All SIM management features are backed with RESTful API, which allows integrating SIM management with existing device management platforms or systems. If you're interested in diving deeper into functionalities of 1oT Terminal, we recommend visiting the product page or going through various blog posts.

The additional value of 1oT eSIM is related to supply chain optimisation. Companies can simplify global operations using one eSIM component, which is available in industrial and consumer-grade both in 2/3/4 triple-cut form factor, and MFF2 embedded chip size. The same goes for the CMP, integrations, dedicated point of contact and technical support, which will help companies focus on their core business.


1oT has an ambitious roadmap to solve permanent roaming restrictions in more countries, thus opening potential new markets to our new and existing customers.

The localised profile in Brazil is one of many that 1oT's eSIM has to offer. Our goal in 1oT is to provide our customers with flexibility, insurance, and extended coverage worldwide.
