As the Internet of Things (IoT) continues to revolutionize industries worldwide, the need for seamless, secure, and reliable connectivity has never been more critical. However, no single connectivity type can meet the diverse requirements of IoT applications. Global IoT deployments face challenges like network certifications, roaming restrictions, legacy network phase-outs, and scalability and security concerns. Moreover, terrestrial networks cover less than 20% of the Earth’s surface, leaving significant coverage gaps. Multi-network SIMs, utilizing multi-IMSI and eUICC technologies, provide a solution to these challenges, offering flexibility and continuous connectivity.
3GPP Release 17 enables the integration of cellular networks with satellite communications through standardized methods. For instance, multi-IMSI SIMs can incorporate satellite NTN (Non-Terrestrial Networks) as an additional IMSI, allowing devices to seamlessly switch between cellular and satellite networks based on availability, ensuring uninterrupted connectivity.
Whether utilizing multi-IMSI, eUICC, or a combination, thorough planning and testing prior to deployment are essential. By following the right steps before deployment, you can maximize the benefits of multi-network SIMs and guarantee reliable global connectivity from the outset.
