Granite Launches SIM360, a Next-Generation Multi-Carrier Connectivity Platform for IoT and Fixed Wireless Deployments

New carrier-direct SIM technology delivers greater reliability, faster deployment and unprecedented control across all three major U.S. wireless networks

QUINCY, Mass., Sept. 15, 2026 /PRNewswire/ -- Granite Telecommunications, one of North America's largest providers of communications and technology solutions to businesses and government agencies, today announced the launch of SIM360, Granite's next-generation multi-carrier data SIM platform designed to simplify connectivity, improve resilience and streamline carrier management for wireless and IoT deployments.

Built for high-bandwidth IoT and fixed wireless access (FWA) applications, SIM360 comes preloaded with carrier-direct profiles from all three U.S. Tier 1 wireless providers on a single physical SIM card. Through one SIM, one management platform and a single commercial relationship with Granite, customers gain access to multiple carrier-direct, non-roaming networks — without juggling separate contracts, billing or support relationships for each carrier.

Developed in collaboration with Thales, a global leader in cybersecurity and IoT connectivity management, the solution leverages the latest GSMA SGP.32 eSIM architecture and Granite's patent-pending orchestration technology to enable seamless access across the three major U.S. wireless networks, giving organizations the flexibility to select the carrier that best aligns with their coverage, performance and business needs.

"As organizations become increasingly dependent on connected devices and always-on network access, they need greater flexibility and reliability from their wireless services," said Rob Hale, Granite's President and CEO. "SIM360 delivers unprecedented control by bringing all three major U.S. wireless networks together on a single SIM. With SIM360, customers can deploy faster, optimize network performance and maintain business continuity through intelligent access to multiple carrier-direct networks."

"As IoT and fixed wireless deployments scale, businesses need connectivity that can keep them connected when network conditions change," said Guillaume Lafaix, VP Connectivity Solutions and Embedded at Thales. "Working with Granite on SIM360, we're combining Thales' GSMA-certified eSIM technology with Granite's orchestration capabilities to give customers seamless access to all three major U.S. carriers through a single, secure connectivity solution. The result is greater resilience and flexibility, without adding complexity for businesses."

One SIM. Three Major Networks. Total Control.

SIM360 allows customers to select, activate, deactivate and switch between carrier profiles directly through Granite's Enterprise Mobility Management platform (GEMM), enabling remote carrier management throughout the lifecycle of a device. The platform gives customers centralized visibility and control across devices, SIMs and carrier networks — and direct ownership over carrier selection and connectivity policy — through a single interface.

Key benefits of SIM360 include:

• Multi-Carrier Connectivity and Resilience: Preloaded carrier-direct profiles from all three U.S. Tier 1 wireless providers on a single SIM maximize coverage, performance and uptime across non-roaming networks.
• Faster Deployment: Carrier-certified profiles reduce device qualification and deployment timelines.
• Customer-Controlled Carrier Selection: Customers can switch preferred carrier profiles on demand through the GEMM platform.
• No Physical SIM Swaps: Carrier changes happen remotely — no truck rolls, no hardware replacement.
• Carrier-Direct Performance: Direct carrier connectivity supports lower latency and improved network performance.
• Usage Aggregation: Consolidated visibility across carrier networks simplifies administration and optimizes connectivity costs.
• Automated Provisioning and Lifecycle Management: Streamlined activation and ongoing carrier management accelerate deployments and reduce operational complexity.
• Consolidated Billing and Support: One Granite agreement, one invoice and a dedicated U.S.-based support team replace the complexity of managing multiple carrier relationships.

Built for Business Continuity

A cornerstone of SIM360 is its automated multi-carrier failover capability. If a device loses access to its current carrier network due to an outage, network congestion or coverage issue, SIM360 automatically transitions to the next available carrier profile, helping keep critical operations online.

Connected fleets, supply chain and logistics networks, remote offices, field equipment, kiosks, sensors and other mission-critical IoT deployments all depend on always-on connectivity — and SIM360 is built to deliver it. With carrier-direct access across all three major U.S. wireless networks, operations run on the combined strength of three networks working as one.

SIM360 is available now for domestic IoT and FWA deployments. Learn more at granitenet.com/solutions/mobility/sim360.
