News Summary:

On September 5, 2026, a Mobile World Live panel featuring executives from CSG, Red Hat, and GSMA Intelligence, identified artificial intelligence as a key technology reshaping customer care within the telecommunications sector. The panel concluded that as 5G networks achieve comparable speeds and coverage, mobile operators now increasingly differentiate through customer experience, making customer care a primary competitive battleground after previously being secondary to network build-out. Earlier, on September 4, 2026, this same Mobile World Live panel, titled "AI: The customer care game-changer," convened CSG's Chief Strategy and Product Officer, Chad Dunavant, alongside Fatih Nah of Red Hat and Emanuel Kolta of GSMA Intelligence, to explore AI's transformative impact on mobile network operator strategy.
