The first warm days of May have encouraged more of us to plan summer holidays and outdoor activities. We are using our mobile devices more often to check travel routes, book accommodation and browse tourist attractions, increasing demand for fast, reliable mobile connectivity.

Which networks currently offer the best mobile internet, and which are falling behind? Once again, we have prepared a comprehensive, independent operator ranking based on hundreds of thousands of real-world measurements collected in May 2026.

The key finding from our latest analysis is clear: T-Mobile remains the download speed leader, while Orange leads the lowest latency (ping) category. The gap between first and fourth place in 5G download speeds is substantial: the fastest operator delivers download speeds almost four times as high as the operator at the bottom of the ranking.

RFBENCHMARK measurement methodology – where does our data come from?

Our rankings draw their credibility from real-world data. This ranking is based on 285,537 measurements collected in May 2026 directly by users of the RFBENCHMARK mobile app.

In the latest dataset, each operator’s share of the tests was as follows:

• Orange: 34.0%
• Play: 30.1%
• Plus: 18.4%
• T-Mobile: 17.6%

Measurements are taken under everyday usage conditions through crowdsourcing, reflecting the actual experiences of mobile network customers in Poland rather than laboratory testing. Our analysis focuses exclusively on 5G and 4G LTE technologies.

The breakdown of May’s measurements by technology was as follows:

• 4G LTE technology: 54.46% of all measurements. It remains the most widely used radio standard among a diverse range of users across the country.

• 5G technology: 45.19% of all measurements. Its share continues to grow steadily and rapidly, directly reflecting customers’ migration to next-generation networks.

• Older technologies, including 3G: 0.35% of all measurements. They account for only a marginal share of the total as operators progressively retire older-generation networks and repurpose their spectrum.

Mobile internet in Poland – how did networks perform in April 2026?

April’s 5G measurements strengthened T-Mobile’s position as the speed leader. The operator achieved an average download speed of 445.9 Mbps and the highest upload speed of 64.2 Mbps. Orange came second in both categories, with 367.6 Mbps for downloads and 60.0 Mbps for uploads, ahead of Play. Play, meanwhile, recorded the lowest average ping at 22.3 ms, taking the lead in network responsiveness. Plus ranked last in the fifth-generation network comparison, recording the lowest download speed (117.6 Mbps) and the highest network latency (26.9 ms).

T-Mobile’s lead was equally clear on 4G LTE. The operator took first place for both download speeds (69.0 Mbps) and upload speeds (23.7 Mbps), improving on the previous month’s results. In the race for second place in downloads, Orange (50.8 Mbps) outpaced Play (44.1 Mbps), while upload speed differences between the top three operators were minimal. Orange retained its advantage in fourth-generation network latency, recording the lowest ping (29.4 ms). Plus finished last in every LTE category, with the lowest speeds and the highest average latency at 38.4 ms.

FAQ – Frequently asked questions

1. What is the best mobile internet network in Poland?

The answer depends on the network technology and the metric that matters most to the user. Based on RFBENCHMARK’s annual averages for the full year of 2025, the results in the main categories were as follows:

4G LTE performance: On the older LTE technology, T-Mobile also led the annual download speed ranking, while Play recorded the best annual upload speeds. Overall, T-Mobile leads in data transfer speeds in Poland, while Orange leads in lowest ping.

5G speed leader (downloads and uploads): T-Mobile was the annual performance winner on the next-generation network. Across the full year, the operator achieved the highest average download speed of 399.3 Mbps and upload speed of 61.1 Mbps.

Network responsiveness leader (ping): Orange led the ranking for users seeking the lowest latency. In the annual 5G review, Orange took first place with an average ping of 19.9 ms.

2. Who offers the fastest 5G in Poland?

According to measurements collected in May 2026, T-Mobile offers the fastest 5G in Poland. The operator’s average 5G download speed reached 434.9 Mbps. Orange came second with 363.0 Mbps.

3. Which mobile operator has the lowest ping?

Orange recorded the lowest ping, or network latency, in May 2026. Its average ping was 23.2 ms on 5G and 29.4 ms on 4G LTE.

4. What is crowdsourced internet testing?

Crowdsourced testing is a method of collecting data directly from real mobile app users who test their networks on smartphones during everyday use. Unlike laboratory tests or dedicated drive tests, crowdsourcing reflects signal quality, speeds and latency in the places where people actually live, work and travel. All RFBENCHMARK reports are based on this model.
