T-Mobile won five of the six categories in RFBENCHMARK’s September ranking. The operator recorded the highest average download and upload speeds on both 5G and 4G LTE, as well as the lowest ping on 5G. Orange took first place for 4G LTE ping. The highest average download speed reached 458.6 Mbps.

Compared with August, the leaders in the two ping categories swapped places. Meanwhile, average download and upload speeds declined across all four operators on both 5G and 4G LTE. Let’s take a closer look at the results.

Mobile internet in Poland (September 2026)

5G results

Average download speed: T-Mobile (458.6 Mbps)

T-Mobile was the only operator to exceed 400 Mbps. Second-placed Orange achieved 348.5 Mbps, giving the leader an advantage of 110.1 Mbps, or 31.6%. In August, the gap stood at 100.9 Mbps. Play came third (263.0 Mbps), followed by Plus (119.2 Mbps).

Average upload speed: T-Mobile (66.5 Mbps)

T-Mobile outpaced second-placed Orange (58.3 Mbps) by 8.2 Mbps. Third-placed Play (57.3 Mbps) narrowed the gap to Orange from 2.5 Mbps in August to 1.0 Mbps. Plus recorded 26.7 Mbps, less than half Play’s result.

Lowest ping: T-Mobile (23.0 ms)

T-Mobile took first place from Orange, which had led this category in June, July and August. T-Mobile beat Orange (24.3 ms) by 1.3 ms. This was also T-Mobile’s best result between June and September. However, it remained higher than Orange’s winning results in June (22.3 ms) and July (21.9 ms).

Play (26.9 ms) and Plus (28.4 ms) took the remaining places. All operators recorded results below 30 ms, unlike in August, when Plus registered 30.6 ms.

4G LTE results

Average download speed: T-Mobile (68.6 Mbps)

T-Mobile outpaced second-placed Orange (51.3 Mbps) by 17.3 Mbps, or 33.7%. Despite recording the largest decline in this category (down 5.1 Mbps), the leader maintained a clear advantage. Play (45.3 Mbps) and Plus (40.1 Mbps) followed, separated by 5.2 Mbps.

Average upload speed: T-Mobile (23.2 Mbps)

T-Mobile was 1.6 Mbps faster than Orange and Play, which both recorded 21.6 Mbps. Plus achieved 17.4 Mbps. The gap between the highest and lowest results was 5.8 Mbps, compared with 39.8 Mbps on 5G.

Lowest ping: Orange (30.3 ms)

Orange beat T-Mobile (30.8 ms) by 0.5 ms, reclaiming the lead it had lost in August. Such a small difference should not be interpreted as evidence of a noticeable advantage for one network over the other.

The gaps to Play (32.7 ms, 2.4 ms behind the leader) and Plus (38.7 ms, 8.4 ms behind) were larger. No operator recorded a ping below 30 ms on 4G LTE.
