Interop expands RBM across regional U.S. operators
FORT MYERS, Fla., April 8, 2026 — Interop Technologies, a global leader in advanced mobile messaging technology, today announced that C Spire, a privately held national advanced technology company and largest independent wireless operator in the United States, has selected Interop to provide RCS business messaging (RBM) management services.
C Spire joins a growing group of regional U.S. carriers working with Interop to introduce RBM across their networks and will be the first to process live RBM traffic using Interop services.
With commitments secured from multiple U.S. operators, Interop is set to enable more than two million regional subscribers for RBM in 2026. This represents the largest and most recent coordinated expansions of RCS business messaging within North America.
“Interop’s history as a messaging leader speaks for itself and their deep expertise in RCS technology makes them a natural partner for C Spire as we introduce advanced business messaging to our customers,” said Charles Watson, senior vice president, network operations at C Spire. “Their continued focus on the operator, including flexible deployment and comprehensive management of their services, aligns with our customer inspired promise by expanding next-generation messaging capabilities for our subscribers.”
Through Interop’s RBM management capabilities, C Spire gains enhanced visibility and operational control over all RCS business messaging ecosystem activities while enabling enterprises to engage subscribers with rich, interactive messaging experiences directly within the native messaging client.
“Interop has spent more than two decades developing solutions for mobile operators as messaging technologies continue to evolve,” said Stephen Zitnik, chief technology officer at Interop Technologies. “As RCS business messaging expands globally, operators are looking for trusted partners with the experience and operational expertise to introduce these services seamlessly into their networks and scale them effectively. Our focus remains on ensuring operators can deploy RBM with the visibility, oversight and operational control needed to manage and support rapid enterprise messaging growth.”
Interop’s RBM management services provide operators with the governance and operational tools required to introduce RBM at scale, including:
• Brand and campaign ingestion and management
• RBM enablement and onboarding oversight
• Messaging traffic visibility and monitoring
• Operator-controlled monetization frameworks
• Integration with existing messaging infrastructure
These capabilities enable operators to support enterprise messaging while maintaining control over how RBM services are introduced and managed within their networks.
