SEALSQ Commences Global Deployment of its GSMA-Accredited eUICC with Telcos, Integrating A Pioneering Post-Quantum Ready Cryptographic Security Technology

July 08, 2025 09:15 ET | Source: SEALSQ Geneva, Switzerland, July 08, 2025 (GLOBE NEWSWIRE) -- SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced that is has commenced the deployment of its GSMA-accredited eUICC (Embedded Universal Integrated Circuit Card) with telecommunications operators (Telcos) worldwide. SEALSQ’s GSMA-accredited eUICC technology is now equipped to integrate Post-Quantum cryptographic security, marking a major milestone in the evolution of secure mobile and IoT communications. This innovation enables mobile phones, IoT devices, and connected infrastructure to benefit from next-generation security that defends against current and future cyber threats, including those posed by quantum computing. “By preparing Post-Quantum security for our GSMA-accredited eUICC technology, we’re enabling a new era of trusted, scalable, and future-proof connectivity,” said Carlos Moreira, CEO of SEALSQ. “This advancement meets today’s security needs and prepares for future quantum threats, ensuring our customers stay ahead of emerging cyber challenges.” A Swiss GSMA Accredited Root of Trust At the heart of SEALSQ’s solution is its GSMA Root CI-accredited Root Certificate Authority, hosted in Switzerland to ensure digital sovereignty through the nation’s legacy of trust, neutrality, and stringent data privacy. This Swiss RoT ensures maximum trust and interoperability across the global mobile ecosystem, supporting secure identification and authentication of eSIMs and Subscription Management entities within the GSMA Remote Provisioning framework, paving the way for secure, remote, and scalable connectivity for Consumer, M2M, and IoT devices. As eSIM adoption surges, Telcos are actively seeking to phase out physical SIM cards in favor of dynamic, remotely provisioned profiles. SEALSQ’s eUICC technology simplifies this transition by providing a secure, Post-Quantum-ready platform that enhances operational efficiency and ensures long-term cryptographic resilience. Powering the Next Generation of Smart Cities and Industry 4.0In smart city deployments, where millions of sensors collect data on traffic, environment, and infrastructure, SEALSQ’s Post-Quantum-ready eUICC ensures end-to-end trust, data integrity, and resilience, even as cyberthreats evolve. Municipalities and service providers can confidently roll out IoT solutions to improve efficiency, safety, and urban sustainability. For industrial IoT applications, the technology offers secure, seamless connectivity for sensors, machinery, and automated systems across sectors such as manufacturing, logistics, and agriculture, safeguarding mission-critical data. Expanding into Space: Telcos Gain Access to WISeSat ConstellationIn a strategic extension of its connectivity services, SEALSQ has become an investor and shareholder in WISeSat.Space, a pioneering satellite company developing a constellation of low-orbit satellites for secure IoT connectivity. Through this partnership, SEALSQ enables Telcos to access the WISeSat satellite constellation, extending Post-Quantum-ready services from Earth to space, providing resilient, globally accessible infrastructure for mission-critical IoT, remote environments, and underserved regions. Safeguarding Mobile Phones Against Quantum ThreatsMobile phones, reliant on traditional cryptographic algorithms like RSA and ECC, are vulnerable to quantum computing-based attacks. SEALSQ’s Post-Quantum-ready eUICC provides robust encryption that future-proofs mobile communications, financial transactions, and authentication processes—protecting user privacy and device integrity at scale. A Future-Proof Opportunity for Telcos and EnterprisesThis deployment marks a turning point for Telcos seeking to enhance security, reduce complexity, and enable new business models in the age of AI and quantum computing. With SEALSQ’s Post-Quantum-ready eUICC, operators, enterprises, and governments have a trusted path to secure digital transformation across mobile, IoT, and infrastructure domains.
