Heddian and Giesecke+Devrient Announce Partnership to Launch Heddian’s UtiliSIM™ for Utilities
New SIM Solution Sets Standard for Secure, Flexible Connectivity in Utility Sector
Arlington, Virginia, February 3, 2026 — Heddian and Giesecke+Devrient (G+D), global leaders in secure communications and connectivity, are pleased to announce a strategic partnership to deliver Heddian’s UtiliSIM™, an innovative SIM card designed to meet the unique needs of electric utilities operating on LTE networks. This collaboration marks a significant advancement in secure, reliable, and flexible network solutions for both private and commercial LTE traffic in the utility sector.
About UtiliSIM: Purpose-Built for Electric Utilities
Heddian’s UtiliSIM is engineered specifically for utilities, enabling seamless connectivity across LTE networks. The solution supports both private and commercial LTE traffic, offering utilities the flexibility to manage their communications infrastructure efficiently. With UtiliSIM, utilities gain access to robust connectivity, enhanced security, and the agility required for today’s dynamic energy landscape. The multi-carrier connectivity options provide additional resiliency as the device can failover to another commercial carrier if the primary commercial network fails.
UtiliSIM is designed to allow utilities to deploy using commercial network coverage while contemplating private networks over time. Once private networks are deployed, a new profile can be securely downloaded over the air eliminating the need for a truck roll to change the SIM. The SIM will be available in several form factors as well as eSIMs for a growing number of Internet of Things (IoT) devices.
UtiliSIM is part of a suite of products and services from Heddian that reduce complexity and cost for utilities to deploy secure and reliable networks for grid communications.
Technology Highlight: SGP.32 Standard and Advanced Security
Heddian’s UtiliSIM leverages the SGP.32 standard for secure remote SIM provisioning, ensuring utilities can deploy and manage SIM profiles safely and efficiently. The SIM card features built-in security to safeguard sensitive data and network access, while its flexible IMSI handling enables adaptable identity management for diverse operational needs. Together, these capabilities provide a future-ready solution for utilities looking to modernize their network infrastructure.
G+D is fully certified by the GSMA meaning its products and facilities are built with “security-by-design” philosophy and undergo rigorous production-level security testing to minimize the risks of tampering and unauthorized access. The certification also ensures interoperability across networks and remote provisioning support. This offering is built using G+D’s AirOn360® eSIM Management Platform (eIM)/SGP.32 solution, SM-DP+, Connectivity and SGP.32 UICCs
