Zong has once again emerged as the top-performing mobile network in Pakistan, according to the Pakistan Telecommunication Authority’s (PTA) independent Quality of Service (QoS) survey for the third quarter of 2025.
The survey, which covered 17 cities and two major roads, and included roughly 46,000 voice calls and SMS tests plus about 0.33 million broadband samples, placed Zong first in several critical categories, including 4G coverage, voice quality, and SMS performance, and multiple broadband throughput metrics.
Jazz was in second place overall, while Ufone and Telenor came in at 3rd and 4th, respectively. Here is a detailed breakdown of network rankings in each performance category.
4G Coverage and Voice Calls
Zong led the chart in mobile network coverage across 15 cities for 4G and in 11 cities for 3G, placing it first in the coverage ranking. By comparison, Jazz recorded 13 compliant 4G city results and Ufone 12, while Telenor lagged with compliance in only six cities for 4G.
In terms of voice calls, which is a composite of Network Accessibility, Call Setup Success Rate (CSSR), Call Connection Time (CCT), Call Completion Ratio (CCR), and Mean Opinion Score (MOS), Zong topped the standings with 86 compliant voice QoS KPIs against 9 non-compliant.
Latency and Web Browsing
Latency results show a more nuanced performance. In the PTA’s auto-mode latency, Zong’s average was higher than the very best performers (the survey summary shows average latencies of Jazz ~68 ms, Telenor ~67 ms, Zong ~77 ms, and Ufone ~98 ms), placing Zong behind Jazz and Telenor on this specific metric. However, in 3rd-party app latency testing, Zong remained broadly compliant across almost all cities (18 compliant, 1 non-compliant), tying it with Ufone for second place in the 3rd-party latency standings.
For web page loading time, Zong trailed leaders Ufone and Jazz (Zong was compliant in 13 cities and non-compliant in 5), indicating that while Zong’s raw throughput and upload performance are ahead of others, web-page QoE still favored some competitors in a handful of locations.
Jazz remained competitive, particularly for auto-mode download throughput (leading in 11 cities), and Telenor and Ufone each led in selected non-service KPIs (latency, web page loading) across parts of the survey footprint.
This is a comparative report and does not cover all of Pakistan. A mobile network winning this survey does not mean it is a flawless performer, but simply ahead of others in the 17 cities covered in the test.
