As the global mobile virtual network operator (MVNO) market surges towards a projected $137 billion by 2030, eSIM Go, a digital connectivity pioneer, is scaling for future growth. With its modernised user platform, developed in collaboration with CSG® (NASDAQ: CSGS), eSIM Go will simplify and speed up the MVNO journey, enabling faster onboarding, richer self-service and seamless integration of digital offerings.

“Businesses from fintechs to airlines are looking to deepen customer relationships by offering custom digital mobile services. But becoming an MVNO has traditionally been a slow, complex and inflexible process,” said Zacc Couldrick, CEO, eSIM Go. “As we aim to eliminate the barriers to entry into the digital connectivity space, we needed a technology provider with deep network relationships and a history of simplifying complex processes. With CSG’s proven, cloud-native technology, we’ve built a platform that makes it easy to launch, integrate and personalise connectivity offerings that customers truly value.”

eSIM Go’s next-generation platform allows businesses to deploy new wireless services in as little as 48 hours. By integrating CSG Ascendon into the platform, eSIM Go customers benefit from streamlined onboarding and offboarding, and a fast, intuitive self-service experience. Whether scaling a product portfolio or entering new markets, eSIM Go customers can move with greater speed and agility to meet the evolving demands of a digital economy.

“We’re seeing a resurgence in MVNO innovation, as businesses create tailored connectivity services for niche and underserved markets,” said Sean Casey, SVP, Product Management, CSG. “In a complex partnership ecosystem, eSIM Go’s modernised platform redefines what’s possible, making MVNO onboarding faster, easier and more scalable while building loyalty that lasts. This is a pivotal step in the evolution of digital connectivity, and it’s an honour for CSG to support eSIM Go as it leads the charge in delivering simplified, future-ready solutions for sustainable growth.”
