Jazz, Pakistan’s leading digital operator under JazzWorld, has successfully completed a Proof of Concept (PoC) for a fully converged Single Voice Core (SVC), marking a major milestone in the country’s telecom network evolution.
The PoC, conducted in collaboration with Huawei, validated the technical and operational feasibility of consolidating multi-generation voice services onto a unified core platform. The trial evaluated the integration of traditional 2G voice services alongside VoLTE (Voice over LTE) and VoWiFi within a single intelligent architecture.
Simplifying Architecture, Preparing for 5G
The initiative aimed to measure performance improvements, architectural simplification, interoperability between legacy 2G and 4G/VoLTE layers, and overall readiness for future 5G voice services.
Commenting on the development, Khalid Shehzad, Chief Technology Officer at JazzWorld, described the trial as a significant step in the company’s modernization strategy. He noted that unifying voice services across generations onto a single core simplifies network design while future-proofing it for next-generation technologies.
Performance Gains and Customer Impact
According to trial results, the converged SVC demonstrated:
- Reduced call setup times compared to traditional network architectures
- Improved call stability
- Enhanced voice clarity
These improvements are expected to accelerate large-scale VoLTE adoption and enhance the everyday calling experience for millions of users. For customers, this translates into clearer calls, fewer dropped connections, and more reliable service — both on current 4G networks and future 5G deployments.
Nationwide Infrastructure Advantage
Jazz currently serves over 73 million customers and holds approximately 37 percent market share in Pakistan. With more than 30,500 kilometers of optical fiber backbone and over 17,800 active base stations nationwide, the operator is strategically positioned to roll out the unified voice core at scale.
The successful PoC places Jazz among regional telecom leaders advancing toward fully converged network architectures, reinforcing its focus on quality, efficiency, and long-term technological readiness.
