Jazz, Pakistan’s leading digital operator from JazzWorld, has successfully completed a Proof of Concept (PoC) for a fully converged Single Voice Core (SVC), validating the technical and operational feasibility of unifying multi-generation voice services onto a single voice platform.

Conducted in collaboration with Huawei, the PoC aimed to evaluate the consolidation of 2G voice services alongside VoLTE and VoWiFi services within a unified core architecture. The objective was to assess performance improvements, architectural simplification, interoperability across 2G and 4G/VoLTE layers, and readiness for future 5G voice evolution.

Commenting on the milestone, Khalid Shehzad, Chief Technology Officer at JazzWorld, said, “The successful trial of a fully converged Single Voice Core marks an important step in Jazz’s network modernization journey. By unifying voice services across all generations onto a single intelligent core, we are simplifying our architecture while future-proofing it for next-gen technologies. This enables better service quality today and a more agile platform for future innovation.”

Built on Pakistan’s widest nationwide network, the planned SVC deployment is expected to accelerate large-scale VoLTE adoption. Trial performance indicators show meaningful reductions in call setup time compared with traditional networks, alongside improved call stability and voice clarity. These gains are expected to enhance everyday calling experiences at scale, reinforcing Jazz’s leadership in network quality.

Today, Jazz serves over 73 million customers and holds the highest market share in Pakistan at 37 percent. With more than 30,500 kilometers of optical fiber backbone and over 17,800 active base stations, Jazz is well-positioned to deliver high-quality voice services consistently across the country. For customers, this translates into clearer calls, faster call setup, fewer drops, and more reliable connectivity – whether on 4G today or future 5G networks.
