T-Mobile won five of the six categories in RFBENCHMARK’s August ranking. The operator recorded the highest average download and upload speeds on both 5G and 4G LTE, as well as the lowest average ping on the fourth-generation network. Orange took first place for 5G latency. The highest average download speed in the ranking reached 467.0 Mbps.

Which network performed best in measurements taken towards the end of the summer holidays? The August results reveal clear differences between operators, particularly in 5G download speeds. The competition for the lowest LTE latency was much closer, with just 0.3 ms separating the top three operators. Let’s take a closer look at the results.

RFBENCHMARK measurement methodology – where does our data come from?

RFBENCHMARK’s regular rankings are based on measurements taken by users of its mobile app. This data collection model, known as crowdsourcing, enables us to analyse connection performance under everyday usage conditions. Three key metrics are measured: download speed, upload speed and latency, also known as ping.

The August ranking covers the period from August 1 to 31, 2026 and includes 202,688 individual measurement results across the measured parameters. 4G LTE accounted for 106,820 results, or 52.70% of the total, while 5G accounted for 95,286 results, or 47.01%. The remaining 582 results, representing 0.29%, came from older technologies, which are not covered in detail in this report.

The largest share of the collected dataset came from Orange, with 70,063 results (34.57%). It was followed by Play with 61,574 (30.38%), Plus with 37,082 (18.30%) and T-Mobile with 33,969 (16.76%). Percentages have been rounded.

These counts represent the combined number of download, upload and latency measurements, rather than the number of unique users or complete speed tests. The breakdown shows each operator’s and technology’s share of the recorded results and should not be interpreted as an indication of market share or network coverage.

Mobile internet in Poland (August 2026)

5G results

Average download speed: T-Mobile (467.0 Mbps)

The highest average 5G download speed was recorded by T-Mobile at 467.0 Mbps. Orange came second with 366.1 Mbps, followed by Play in third place at 275.1 Mbps. Plus ranked fourth with 127.1 Mbps.

Average upload speed: T-Mobile (67.7 Mbps)

T-Mobile also led the upload speed category, averaging 67.7 Mbps. It was followed by Orange at 60.0 Mbps and Play at 57.5 Mbps. Plus came fourth with 27.6 Mbps.

The competition between Orange and Play was much closer in this category than in download speeds, with just 2.5 Mbps separating the two operators. T-Mobile, meanwhile, led the runner-up by 7.7 Mbps.

Lowest ping: Orange (23.9 ms)

In the latency category, Orange took first place with an average ping of 23.9 ms. Play recorded a slightly higher result of 24.9 ms. T-Mobile came third at 26.4 ms, followed by Plus at 30.6 ms.

Orange beat Play by 1.0 ms, while the gap between the lowest and highest average latency across the networks tested was 6.7 ms. The operator leading the speed categories therefore did not also lead the 5G ping ranking.

4G LTE results

Average download speed: T-Mobile (73.7 Mbps)

On 4G LTE, the highest average download speed was recorded by T-Mobile at 73.7 Mbps. Orange came second with 54.3 Mbps, followed by Play at 46.9 Mbps and Plus at 41.8 Mbps.

T-Mobile outpaced Orange by 19.4 Mbps. The gap between the third- and fourth-placed networks was smaller, with Play recording a result 5.1 Mbps higher than Plus. The operators ranked in the same order as in the 5G download speed category.

Average upload speed: T-Mobile (23.9 Mbps)

The highest average LTE upload speed was recorded by T-Mobile at 23.9 Mbps. Orange and Play both achieved 22.1 Mbps, sharing second place when results are rounded to one decimal place. The lowest average was recorded by Plus at 17.6 Mbps.

The leader’s advantage over Orange and Play was 1.8 Mbps. Upload speed was therefore a category in which the differences between the top three operators remained relatively small.

Lowest ping: T-Mobile (30.7 ms)

T-Mobile also took first place for average LTE latency, recording 30.7 ms. Close behind were Orange at 30.9 ms and Play at 31.0 ms. A higher average ping was recorded on the Plus network at 40.7 ms.

The gap between the top three operators in this category was very small. T-Mobile beat Orange by 0.2 ms and Play by 0.3 ms. Although this puts T-Mobile first based on the published averages, such small differences should not be interpreted as evidence of clearly superior network performance in every situation.
