The silent revolution of the eSIM transforms the rules of the global Internet of Things (IoT), but are companies prepared to manage thousands of devices in real time without depending on a single mobile operator? The arrival of the new SGP.32 standard serves to eliminate barriers and frictions to the unstoppable process of eSIM adoption in connected devices, but it is necessary to understand the scope and implications of this new standard.
The replacement of traditional SIM cards with SIM based on eUICC (eSIM) technology, which allows managing and loading profiles remotely and extending the life cycle of devices deployed in the field, is unstoppable in the global IoT ecosystem.
The arrival of the SGP.32 standard unlocks the true potential of the eSIM and allows manufacturers and global solution providers to overcome many of the historical challenges of connectivity, while improving the efficiency and security of daily operations without friction, in a context of rapid expansion of the Internet of Things (IoT).
In fact, 84% of IoT decision makers plan to implement eSIM in their organizations in the next three years, and almost four in ten are confident that more than half of their new connections will operate under eSIM this year, according to a recent buying guide published by Wireless Logic to help companies adopt the SGP standard.32.
However, and although the arrival of SGP.32 opens the door to the mass adoption of the eSIM, the challenges are not minor. “The transition from SIM to eSIM goes far beyond a technological change: it introduces a level of operational complexity and coordination within the connectivity ecosystem that forces companies to rethink their processes, their device base and their global strategy,” says Asier Culebras, Managing Director of Wireless Logic Spain, who highlights that one of the key challenges is the disparity in requirements depending on the manufacturer or supplier.
Ecosystem knowledge
Among the main challenges are the diversity of requirements depending on the manufacturer, the country or the use case, as well as the need to orchestrate multiple operators, profiles and connectivity policies without compromising the continuity of the service. In this scenario, experience and knowledge of the ecosystem become decisive. Even so, migrating to eSIM is a logical and necessary step for organizations seeking to scale their IoT deployments in a sustainable way. , SGP.32 acts as a catalyst for this process, offering a standardized framework that returns control of connectivity to companies.
What is SGP.32 and how does it work?
As highlighted by Wireless Logic, SGP.32 is the latest GSMA standard for remote SIM provisioning (RSP) and aims to unify and optimize existing specifications to facilitate the mass adoption of eUICC technology, the basis of eSIM and iSIM. Traditionally, eUICC technology has been supported by two main standards: SGP.02 (also known as the M2M standard) and SGP.22 (or consumer standard). The first is based on a push model, in which the provisioning of new profiles must be initiated from the server, while the second introduces a pull model, but requires human intervention. SGP.32 introduces a new architecture that significantly reduces human involvement and allows IoT devices to manage profiles remotely, in bulk and in a standardized way, eliminating the need for complex bilateral integrations between operators.
The SGP.32 architecture is aligned with the global expansion of the Internet of Things. According to IoT Analytics, in 2025 the barrier of 20 billion connected devices globally was expected to be surpassed. “Over the next ten years, annual growth of more than 10% is estimated, which opens up endless business opportunities, but also tests the operational capacity of companies to manage massive fleets of devices on a global scale. This is where SGP.32 becomes really necessary,” says Asier.
Faced with this new paradigm, companies that are already migrating their technology and connectivity must rely on expert alliances, capable of accompanying them in such a profound change. “Addressing this challenge efficiently requires relying on reliable partners, with real experience in global IoT deployments and the ability to orchestrate complex connectivity environments,” warns Asier.
The role of Wireless Logic
As SGP.32 begins to realize many of the historic promises of the eSIM, such as flexibility, control and scalability, many questions are arising among product designers, operations managers and cybersecurity teams. Understanding what this standard really entails, when it makes sense to adopt it, and how to do so without taking unnecessary risks is key to turning technology into a competitive advantage.
Given this paradigm shift, it is key to have a framework that helps companies navigate judiciously through the global complexities of this new scenario. Wireless Logic, a leading global provider of IoT connectivity, has created a guide to help companies navigate SGP.32 and answer the questions on the minds of thousands of professionals. How does eSIM reduce logistics complexity in global markets? Can you help me shorten time to market? How can the tangible benefits of SGP.32 be measured?

These are just some of the questions raised and answered by this new guide, which aims to become a key reference document for any company with globally connected devices. The guide can be downloaded at this link, and although it is currently only in English, it will soon be available in Spanish. “This guide focuses on an aspect that is often underestimated: the operational complexity that SGP.32 introduces. Questions such as who should manage the profiles, how to structure a pilot to demonstrate value quickly or what capabilities a provider should offer to orchestrate connectivity at scale are a central part of the document,” explains Alayn Endaya, Marketing Manager of Wireless Logic Spain.
The eSIM gets older
Behind IoT devices and new forms of connectivity, business models that are increasingly critical to daily operations are being consolidated: from connected vehicles and remote video surveillance to smart energy, medical wearables or advanced security systems. They all share the same fundamental requirement: continuous, secure and frictionless connectivity, capable of operating on a global scale, without interruptions or latency, and of supporting services that are already part of the core of the business.
In this scenario, the arrival of SGP.32 marks a turning point. As highlighted by Wireless Logic, the new standard allows companies to regain control over their IoT connectivity, reduce historical dependence on a single operator and manage connectivity as a strategic asset, and not as a technical condition.
With SGP.32, eSIM evolves from a technological promise into a mature operational framework, enabling more efficient, scalable and resilient deployments, and laying the foundation for a new generation of IoT solutions designed for frictionless growth.
