How GSMA SGP.32 is Revolutionizing IoT Connectivity

As digital connectivity expands across IoT and consumer technology, industrial applications are reshaping communication. However, this growth also increases security risks and provisioning complexities. Companies must address these challenges to ensure seamless global IoT connectivity.

Cybercriminals increasingly exploit IoT vulnerabilities, as many devices lack robust security due to limited processing power. With IoT devices collecting vast amounts of personal data, 55% of IT professionals cite IoT security as a top concern. Additionally, existing eSIM provisioning standards often lack flexibility, hindering large-scale deployments [1]. Figure 1 shows IoT Connectivity.

Introducing GSMA SGP.32

To overcome these challenges, GSMA introduced the SGP.32 eSIM IoT Technical Specification in May 2023. This new standard enhances IoT connectivity through:

• Scalability & interoperability across diverse IoT ecosystems.
• Simplified integration for seamless provider switching.
• Enhanced security across the device lifecycle.
• Improved efficiency to accelerate time-to-market.

With SGP.32, manufacturers can streamline production and configure devices later in the process, improving flexibility and reliability. Enterprises gain access to more service providers and global connectivity options, supporting industries like healthcare, utilities, and agriculture with resilient, secure communication across multiple networks.

Preparing for a Connected Future

The GSMA SGP.32 standard will drive greater connectivity throughout a device’s lifecycle, accelerating IoT market growth. As it gains traction, SGP.32 is set to become the leading eSIM IoT remote provisioning standard for future deployments.

Although introduced in 2023, widespread adoption is expected this year. Companies must ensure their IoT platforms align with the new standard to stay competitive. With the IoT market projected to reach $622 billion by 2030 and 40 billion connected devices, bridging the global connectivity gap remains a priority.

Collaboration is key to advancing security and connectivity. In 2024, the IoT M2M Council and Global Certification Forum formed a Joint Task Force to develop a global cybersecurity certification for IoT services [2]. As the eSIM market is forecasted to hit $16.3 billion by 2027, stakeholders—from manufacturers to regulators—must prepare for a digital future where GSMA SGP.32 is central to IoT connectivity.
