Fleet Management IoT Connectivity Solutions

From Complexity
to Control

Founded in 2005, Voxter is a Brazilian IoT solutions provider specializing in GPS tracking systems, covering the complete journey of vehicular tracking, with connectivity (M2M chips), software (white label platform), and equipment (trackers).

As the company scaled its operations and launched its trackers called J16,  it sought a connectivity partner that could match its pace, offering flexibility, regional coverage and automation of key connectivity management tasks. By integrating emnify’s API-first platform, Voxter gained full control over SIM lifecycle management and multi-network coverage across Brazil and more than 10 LATAM countries, accelerating growth while simplifying connectivity operations.

To simplify operations further, being able to carry out SIM provisioning and activation directly from Lata, their own chip management platform, Voxter removed the complexity of having to use a separate interface for connectivity management.

Challenge 1

Gaining Full Control Through API-Driven Connectivity

As Voxter’s platform and solutions portfolio expanded, so did the need for operational autonomy. Traditional carrier integrations restricted their ability to manage connectivity independently.

What Voxter needed was a fully API-integrated solution - one that would let them troubleshoot devices remotely, adjust data plans dynamically and apply custom service policies based on network behavior or device type. With these capabilities now embedded directly into Lara, Voxter’s team can manage connectivity on their terms, without relying on external portals or manual interventions. 

Solution 1

Cloud-native connectivity with real API control

emnify’s modern platform gave Voxter the autonomy it was missing. Through well-documented APIs and great efforts from its development team, Voxter directly embedded SIM provisioning, diagnostics, consumption tracking and remote commands into its own systems, enabling its customers to manage connectivity from Voxter’s Lara platform instead of emnify’s dashboard.

According to CEO Rafael Medeiros, one of the biggest differentiators was the speed and control emnify provides. “The operation is completely in our hands,” he shared at Exposec. This autonomy not only accelerated internal workflows but also became a value Voxter extended to its customers, giving them real-time visibility and control over their devices.

Sentinela Platform Launch

In June 2025, Voxter launched Sentinela, an online software integrated with the Lara Management platform and dedicated to J16 trackers. Customers who own Voxter J16 trackers (model 2025 onwards) can count on Sentinela's unmistakable and persistent surveillance at no additional cost.

All Voxter J16 trackers report their current settings to Sentinela at least once a day. During this “daily visit,” the tracker also collects the commands queued in Sentinela, allowing new parameters to be set without the need to send SMS messages and overwriting the commands that are active at that moment.

Among the possible commands to be queued, Voxter's Sentinela even allows you to prioritize a specific operator. In other words, a command from the tracker, but one that acts on the behavior of your emnify chip. In addition to changing the priority network, other available commands include changing the password, APN, port, DNS, and others, all executed through emnify connectivity.

This launch significantly boosted Voxter’s ability to deliver instant provisioning and robust device management, further reinforcing speed and control for both Voxter and its customers.

Challenge 2

Scaling Coverage with ANATEL-Approved Multi-Network Access

To expand their vehicle tracking portfolio across Brazil and into Latin America, Voxter required broader and more reliable coverage, particularly with access to a Claro MVNO and guaranteed ANATEL compliance. Their existing partners couldn’t meet the demands for national reach, flexibility, and regulatory alignment. A scalable,  multi-network solution was key to growing their footprint without sacrificing service quality or compliance.

Solution 2

Multi-network SIM Cards
with regulatory coverage

emnify brought multi-network connectivity on a single SIM, giving Voxter access to Claro and other leading, local networks with Anatel regulatory approval. Connectivity now scales from urban hubs to remote areas and across more than 10 countries in South America, all from a single SIM card and platform.

Services Used:

  • Global IoT SIM with multi-network access and ANATEL approval
  • API-first connectivity platform with real-time control and monitoring
  • SIM Lifecycle Management APIs for provisioning, suspension, and termination
  • Remote connectivity commands and diagnostics embedded into Voxter’s Lara platform
  • Custom service policies for data control and anti-theft measures 

emnify's offering is a game changer for our portfolio. It’s a high-quality, flexible solution. Emnify’s SIM card provides fast and stable connectivity wherever our partners’ devices are in the country – and even outside the country.

This solution significantly enhances our customers' operational efficiency, making emnify connectivity a valuable addition to our product portfolio, together with our strategy of providing affordable, high-quality solutions for the vehicular tracking market."
