The beginning of summer and the first heatwave have effectively driven us out of our homes. At the end of June, the holiday season officially launched, bringing with it a massive test for network infrastructure in Poland’s most popular tourist spots. Before we pack our bags for good, let’s check how domestic operators are entering this hot period and who currently offers the best connection parameters.

Who earned the title of leader this time, and who needs to quickly catch up before the peak of holiday trips? Welcome to the detailed report based on the latest data!

June 2026 leaves no doubts – the Polish mobile market has a clear speed leader. T-Mobile once again leads in average data download speed categories, both in 5G technology and the older 4G LTE standard. On the other hand, Orange consistently defends its position as the best choice for those seeking the lowest latency (Ping). Play keeps up bravely with the leaders, while Plus – although recording stable results – still lags behind in most key categories.

RFBENCHMARK measurement methodology – where does our data come from?

Our June report was created based on the analysis of 277,389 measurements performed by users themselves using the RFBENCHMARK mobile application. The so-called crowdsourcing allows us to assess service quality in real-world conditions rather than in sterile laboratories.

User activity across individual networks was as follows:

• Orange: 34.5%
• Play: 30%
• Plus: 18.3%
• T-Mobile: 17.2%

Measurements are conducted under everyday usage conditions (crowdsourcing), which reflects the actual experiences of mobile network customers in Poland, eliminating laboratory tests. The analysis focuses exclusively on the latest technologies: 5G and 4G LTE.

The structure of May measurements by technology is as follows:

• 4G LTE technology: 55.58% of all measurements

• 5G technology: 44.04%

• Older technologies (including 3G): 0.38%

Mobile Internet in Poland – what was the situation in May 2026?

In the May 2026 mobile internet ranking in Poland for 5G technology, T-Mobile maintained its dominance, achieving the highest average download speed (434.9 Mbps) and upload speed (64.1 Mbps). Orange took second place in both categories, but proved to be the best in terms of lowest latency, recording the lowest ping value (23.2 ms). Play took the following positions, while Plus clearly trailed at the end of every category tested, lagging behind the competition.

An identical balance of power emerged in the results for 4G LTE technology. T-Mobile once again dominated the competition in download speed (68.6 Mbps) and upload speed (22.7 Mbps), ahead of Orange and Play, between which upload differences were minimal. Meanwhile, Orange defended its leadership position in the lowest ping category with a result of 29.4 ms. Plus rounded out the ranking once again, recording the weakest results across all fourth-generation network parameters.

FAQ – Frequently Asked Questions

1. Which is the best mobile internet in Poland?

The answer to this question depends on the chosen network standard and the metric that matters most to the user. Looking at RFBENCHMARK’s averaged annual data for the entire year 2025, the situation across key categories is as follows:

4G LTE Alternative: In the older LTE technology, T-Mobile also emerged as the annual download leader, while Play maintained the best annual upload performance. To summarize: in terms of pure transfer speed, T-Mobile dominates in Poland, while in terms of lowest ping – Orange takes the top spot.

5G Speed Leader (Download & Upload): T-Mobile is the annual performance winner in the next-generation standard. Over the full year, the operator achieved the highest average download speed of 399.3 Mbps and an upload speed of 61.1 Mbps.

Leader in Stability and Responsiveness (Ping): Orange remains the top choice for users seeking the lowest latency. In the annual 5G summary, Orange took first place with a record average ping of 19.9 ms.

2. Who offers the fastest 5G in Poland?

According to measurements in May 2026, T-Mobile offers the fastest 5G in Poland. The average data download speed on this operator’s 5G network reaches up to 434.9 Mbps. Second place goes to Orange with a result of 363.0 Mbps.

3. Which mobile operator has the lowest Ping?

The lowest ping (lowest network latency) in May 2026 was recorded by Orange. In 5G technology, its average ping reaches a record 23.2 ms, and in 4G LTE – 29.4 ms.

4. What is crowdsource research in internet testing?

Crowdsource (crowdsourced) research is a method of collecting data directly from real mobile app users testing the network on their smartphones during daily phone use. Unlike laboratory tests or drive tests, crowdsourcing reflects actual signal quality, speed, and latency where people truly live, work, and travel. All RFBENCHMARK reports are based on this model.
