KYIV, Ukraine, Oct. 06, 2025 (GLOBE NEWSWIRE) -- Kyivstar ( KYIV ) , Ukraine’s leading digital operator, has initiated a large-scale network modernization project that will run throughout 2025–2026. The initiative aims to enhance service quality, expand 4G network capacity, and prepare infrastructure for fifth-generation (5G) mobile communications rollout.

Network modernization is a comprehensive set of technical measures aimed at upgrading and developing infrastructure, improving service quality, and enhancing customer experience. This includes replacing outdated equipment, updating radio modules, and more.

While Kyivstar ( KYIV ) conducts regular network upgrades, this large-scale modernization program will deliver substantially higher service quality and unlock new opportunities for customers.

The company is prioritizing modernization of telecom sites with the heaviest traffic — those with the highest number of users and data consumption. Deploying state-of-the-art equipment will increase network capacity and boost data transmission speeds while enabling new software features that allow significantly more data transfer within the same timeframe. This results in faster download speeds and stable service even under heavy network load.

Kyivstar ( KYIV ) is currently analyzing initial results of already-completed work. The modernization effort began with sites most in need of upgrades, and those locations are now demonstrating an average increase of about 30% in data transfer speed and roughly 50% in network capacity.

During equipment replacement and network reconfiguration, short-term changes in mobile internet speed, call quality, and temporary reductions in radio coverage may occur in certain areas. These are standard steps of the modernization process, which will ultimately deliver greater stability and service quality.

Thanks to significant infrastructure investments and ongoing network expansion and modernization, Kyivstar ( KYIV ) has once again been recognized as Ukraine’s Best Mobile Network by Ookla — the global leader in connectivity analytics and developer of the Speedtest service. Based on results from H2 2024 and H1 2025, the operator received all key Speedtest Awards in Ukraine: Best Mobile Coverage, Fastest Mobile Network, and Best Mobile Network.
