Introduction
In a significant development for the Internet of Things (IoT) and fixed wireless access (FWA) sectors, Granite Telecommunications has unveiled SIM360, its next-generation multi-carrier data SIM platform designed to address one of the most persistent challenges in enterprise connectivity: carrier fragmentation. Launched on September 15, 2026, SIM360 represents a major advancement in how organizations manage wireless connectivity across diverse IoT deployments, offering unprecedented control, resilience, and operational simplicity through a single SIM solution that integrates all three major U.S. wireless networks.
The Connectivity Challenge in Modern IoT
As IoT deployments scale across industries—from smart manufacturing and logistics to healthcare and smart cities—the demand for reliable, always-on connectivity has intensified. Traditional approaches requiring separate SIM cards, contracts, and management systems for each carrier create operational complexity, increase costs, and introduce potential failure points. Organizations deploying fleets of connected devices, supply chain sensors, or remote monitoring systems often face difficult trade-offs between coverage, performance, and management overhead.
According to industry analysts, enterprises managing large-scale IoT deployments typically juggle relationships with multiple carriers to ensure geographic coverage and network redundancy. This fragmented approach leads to increased administrative burden, complex billing structures, and delayed response times when network issues arise. The lack of a unified management platform makes it difficult to implement consistent connectivity policies across device fleets.
SIM360: A Unified Approach to Multi-Carrier Management
SIM360 addresses these challenges through its innovative carrier-direct SIM technology, which comes preloaded with profiles from all three U.S. Tier 1 wireless providers on a single physical SIM card. Rather than managing multiple SIM cards and contracts, organizations using SIM360 gain access to multiple carrier-direct, non-roaming networks through one SIM, one management platform (Granite's Enterprise Mobility Management platform or GEMM), and a single commercial relationship with Granite Telecommunications.
The platform leverages the latest GSMA SGP.32 eSIM architecture combined with Granite's patent-pending orchestration technology to enable seamless access across Verizon, AT&T, and T-Mobile networks. This approach eliminates traditional roaming agreements and associated complexities, providing organizations with direct carrier relationships while maintaining the simplicity of a single point of management.
Key Technical Capabilities
SIM360's architecture delivers several critical capabilities for enterprise IoT deployments:
Automated Multi-Carrier Failover: Perhaps the most significant feature is SIM360's ability to automatically transition between carrier networks when connectivity issues arise. If a device loses access to its current carrier due to outage, congestion, or coverage limitations, SIM360 seamlessly switches to the next available carrier profile without manual intervention, helping maintain continuous operations for mission-critical applications.
Remote Carrier Management: Through the GEMM platform, administrators can select, activate, deactivate, and switch between carrier profiles throughout a device's lifecycle. This capability enables dynamic network optimization based on changing requirements, performance needs, or cost considerations without requiring physical SIM replacements.
Centralized Visibility and Control: SIM360 provides centralized management across devices, SIMs, and carrier networks, giving organizations direct ownership over carrier selection and connectivity policy through a single interface. This unified view simplifies monitoring, troubleshooting, and policy enforcement across large-scale deployments.
Carrier-Direct Access: By bypassing traditional MVNO arrangements and connecting directly to carrier networks, SIM360 delivers improved performance, reduced latency, and more reliable service compared to solutions that route traffic through intermediary providers.
Strategic Partnership with Thales
The development of SIM360 involved collaboration with Thales, a global leader in cybersecurity and IoT connectivity management. This partnership combined Thales' GSMA-certified eSIM technology expertise with Granite's orchestration capabilities to create a solution that balances security, flexibility, and operational simplicity.
According to Guillaume Lafaix, VP of 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."
Addressing Critical IoT Deployment Scenarios
SIM360 is particularly well-suited for several high-value IoT use cases where connectivity reliability is paramount:
Connected Fleets and Supply Chain Logistics: Transportation and logistics companies managing thousands of vehicles, containers, and tracking devices benefit from SIM360's ability to maintain connectivity across varying geographic areas and network conditions. The automated failover ensures continuous tracking and monitoring even when individual carrier networks experience issues.
Remote Office and Field Equipment: As hybrid work models continue to evolve, organizations deploying connectivity solutions for remote workers, field technicians, and mobile kiosks require reliable access regardless of location. SIM360's multi-carrier approach provides the redundancy needed for business-critical applications in diverse environments.
Mission-Critical IoT Deployments: Utilities, healthcare providers, and critical infrastructure operators managing sensors, monitoring equipment, and automated systems need connectivity that can withstand network disruptions. SIM360's resilience features help ensure these essential services remain operational during carrier outages or congestion events.
Fixed Wireless Access (FWA): For businesses using wireless broadband as a primary or backup internet connection, SIM360 provides access to multiple carrier networks through a single solution, improving service reliability and enabling intelligent network selection based on performance and availability.
