 Mobileum Inc., a global leader in analytics and network solutions, today announced its expanded role as the appointed verification partner for the GSMA Industry Services’ VOLTIS (Voice over LTE Interoperability & Testing Service) 5G Extension Verification Program. This program advances beyond the existing VoLTE/IMS framework to include 5G readiness verification, enabling mobile operators worldwide to validate next-generation roaming and interoperability through a standardized process.

As the lead verification partner, Mobileum oversees the entire testing lifecycle—from planning and resource validation to execution, troubleshooting, and reporting—providing operators with a streamlined, globally recognized verification experience.

With 5G roaming deployment accelerating globally, complexity in verifying interoperability has grown. The VOLTIS 5G Extension reduces reliance on bilateral tests, enhances service reliability, and expedites roaming partnership formation, meeting the demands of a rapidly evolving mobile ecosystem.

GSMA Industry Services supports over 2,200 customers including operators and device manufacturers, offering trusted frameworks to improve service deployment speed and consistency.

Miguel Carames, Chief Product Officer at Mobileum, stated, “As 5G rollout expands, standardized global verification is essential to overcoming interoperability challenges, facilitating faster deployment of next-gen roaming services.”

Tyler Smith, Head of Industry Services at GSMA, noted, “The 5G readiness extension marks a vital milestone in enhancing end-to-end interoperability worldwide, enabling smoother and more reliable mobile service experiences.”

Market forecasts estimate 5G connections will reach 5.6 billion by 2030, with roaming revenues projected to exceed USD 50 billion by 2027, underlining the criticality of robust verification processes.

Available globally, the VOLTIS Verification Program with its 5G Extension supports operators in securing seamless voice continuity and exceptional cross-border network performance.
