Jazz has completed the virtualization of its Subscriber Data Management platform in collaboration with Nokia, marking a step forward in the operator’s broader network modernization effort. The migration was completed without any disruption to customer services, a detail the company highlighted as a reflection of its engineering capabilities and its commitment to maintaining reliable digital experiences for its customer base across Pakistan. The transformation was carried out using Nokia’s on premises cloud native Subscriber Data Layer, which replaces legacy subscriber data management systems with what the companies describe as a more scalable and resilient architecture.
The migration involved modernizing Jazz’s Home Location Register and Home Subscriber Server infrastructure into a unified, stateless database engine, a shift intended to eliminate architectural silos that had previously separated different subscriber data functions. By consolidating these systems, Jazz aims to create a more agile and efficient environment for managing subscriber data, which underpins core network functions including authentication, mobility management, and service provisioning. Khalid Shehzad, Chief Technology Officer at JazzWorld, said the completed virtualization marks an important step in the company’s transition toward a fully cloud native network, noting that the modernization strengthens network resilience and improves operational agility while creating a foundation for future technologies.
Nokia’s Vice President and Head of Middle East and Africa Services for Mobile Infrastructure, Hatem El Harairi, said the collaboration reflects Nokia’s role in supporting connectivity infrastructure suited to the AI era, adding that the partnership is intended to strengthen the performance and agility of Jazz’s core infrastructure while enabling continued innovation toward more intelligent, cloud native networks. The project builds on an existing relationship between the two companies, which has spanned several previous network modernization initiatives.
Modernizing core network infrastructure has become an increasingly common priority among telecom operators globally, as rising demand for data driven services and digital applications puts pressure on legacy systems that were not originally designed for the scale or flexibility required by current usage patterns. For Jazz, which has continued to invest in network upgrades and data centre modernization in recent years, the completed SDM virtualization adds to a series of infrastructure projects aimed at supporting the rollout of new digital services while maintaining service reliability for its subscriber base. The company said the milestone reflects its ongoing investment in next generation technologies intended to support Pakistan’s broader digital transformation.
