Mobile Internet in Poland – May 2025 Overview

In May 2025, T-Mobile once again dominated the mobile Internet quality ranking in Poland, achieving the best results in both 5G and 4G LTE networks. In 5G technology, the operator offered the highest average download speed (386.3 Mbps) and upload speed (57.5 Mbps), slightly outperforming Orange and clearly leaving Play and Plus behind. However, in the latency (PING) category, Orange took the lead with 18.9 ms, which translates into better performance for services requiring low latency, such as online gaming and video calls.

For the 4G LTE network, T-Mobile again topped the download speed category (55.3 Mbps), significantly ahead of its competitors. Play achieved the best result in upload speed (22.0 Mbps), while Orange was once again the leader in lowest ping (27.0 ms). The May results highlight T-Mobile’s stable position as the speed leader in Polish mobile Internet, while also emphasizing the growing importance of low latency, in which Orange consistently performs best.

How did we collect data for the ranking?

The measurements are collected from users using our mobile application. It allows us to measure the basic parameters of the mobile network – including the level and quality of the signal depending on the technology in which the mobile device works, information about the mobile network operator or the country where the smartphone is located. In addition, on-demand Internet speed measurements are taken during downloads and uploads, as well as a latency test.

When the application notes a low-quality voice call, lack of mobile Internet service or other service, it has the ability to report the user’s current position where the service problem occurred.
