April 9, 2026
Each year, on 9 April, International IoT Day offers more than a moment of recognition. It provides a useful checkpoint to assess how the IoT landscape is evolving in practice, not just in theory.
Since its inception in 2010, the initiative has grown from a series of informal discussions into a globally recognised event. Today, it is observed across industries, academia and technology communities worldwide. What makes it particularly relevant now is that it reflects where IoT stands operationally, not just conceptually.
In 2026, one reality is increasingly difficult to ignore. Connectivity is no longer a supporting function. It is a defining factor in how IoT services are delivered.
From connectivity access to connectivity performance
In earlier stages of IoT adoption, connectivity was primarily about access. The objective was to bring devices online, capture data and validate use cases. Whether connectivity was optimal or not was often secondary.
That approach is no longer viable.
IoT deployments today operate across multiple countries, network environments and regulatory frameworks. They support critical services, from infrastructure monitoring to energy distribution and industrial automation. In this environment, connectivity is directly linked to uptime, service quality and operational continuity.
What matters now is not whether a device can connect, but whether it can maintain stable, secure and predictable connectivity over time.
This shift places new demands on connectivity providers. Organisations expect:
- Consistent performance across different markets
- Resilience when network conditions change
- Visibility and control over connectivity behaviour
- Long-term reliability across extended device lifecycles
Connectivity has effectively moved from a technical requirement to a business-critical capability.
IoT eSIM and SGP.22: redefining deployment models
One of the technologies enabling this transition is IoT eSIM, based on the GSMA SGP.22 specification.
SGP.22 introduced remote SIM provisioning, allowing operator profiles to be downloaded and managed over the air. This removes the need for physical SIM replacement, which has traditionally been a constraint in large-scale or geographically distributed deployments.
The operational impact is significant.
Devices can now be deployed globally with a single SIM form factor and configured remotely once installed. Connectivity can be adjusted without site visits, enabling more agile deployment strategies and reducing operational overhead.
This model supports:
- Faster international rollouts
- Reduced logistics and field service costs
- Greater flexibility in selecting and managing connectivity
- The ability to adapt connectivity over time
As a result, SGP.22 has become widely adopted across sectors such as EV charging, smart metering, logistics and industrial IoT, where scale and reliability are essential.

SGP.32 and the evolution towards autonomous connectivity
While SGP.22 addresses current deployment requirements, the industry is already preparing for the next stage.
SGP.32 has been developed to support IoT environments where devices operate independently, often without user interaction and across long operational lifespans. These scenarios introduce additional complexity in terms of provisioning, lifecycle management and scalability.
The key advancement lies in increased automation.
SGP.32 is designed to:
- Streamline large-scale provisioning processes
- Enable more centralised lifecycle management
- Reduce dependency on device-side logic
- Improve efficiency when managing extensive device fleets
This is particularly relevant for deployments in remote or constrained environments, where manual intervention is not feasible.
Rather than replacing SGP.22, SGP.32 builds on it. The two standards will coexist, supporting different stages of IoT maturity and deployment complexity.
Why infrastructure ownership is becoming a differentiator
As IoT becomes more deeply embedded in critical operations, the underlying connectivity model is receiving greater scrutiny.
The distinction between infrastructure-based operators and aggregation-based models is becoming more pronounced.
Operators with direct control over mobile network infrastructure are typically better positioned to deliver:
- Consistent performance across multiple regions
- Greater transparency in how connectivity is managed
- Faster response times when issues occur
- More predictable long-term service quality
In contrast, models that rely heavily on third-party agreements may face challenges in maintaining consistency at scale, particularly across diverse markets.
For MVNOs and connectivity providers, this raises important strategic questions around control, partnerships and service delivery models.
International IoT Day as a reflection of industry maturity
International IoT Day has evolved alongside the ecosystem it represents.
What was once a forum for exchanging ideas now reflects how those ideas are being implemented at scale.
In 2026, success in IoT is no longer measured by the number of connected devices, but by how effectively those devices are supported by reliable connectivity.
IoT eSIM, through SGP.22 and the emerging SGP.32 standard, plays a central role in this transition. It enables more flexible and scalable connectivity models that align with the operational demands of modern IoT deployments.
A clear direction for the future of IoT
The next phase of IoT will not be shaped by connectivity availability, but by connectivity performance.
As deployments continue to expand, the emphasis is shifting towards stability, control and adaptability. Connectivity must operate consistently across different environments, remain secure over time and support evolving operational requirements.
In this landscape, execution becomes the differentiator.
Ultimately, the question is no longer whether devices can connect, but whether connectivity can be delivered reliably, globally and without compromise.
