The Kuyavian-Pomeranian Voivodeship was the next stop on the nationwide Drive Test survey conducted by the RFBENCHMARK team.

In this region, experts performed detailed quality tests of the services provided by the four major mobile operators: Orange, Play, T-Mobile, and Plus. The tests covered both voice calls (VoLTE and WhatsApp) and 5G data transmission—including speed, latency, and video streaming quality.

The measurements were conducted using 14 devices, including Samsung S24 Ultra smartphones and professional signal analyzers such as PCTEL GFlex and IBFlex. This setup enabled a reliable network analysis across various conditions and usage scenarios.

Mobile Internet Speed in Kuyavian-Pomeranian Voivodeship (2025)

File Transfer Success Rate – Download and Upload

Play achieved the highest download success rate with 99.50%, slightly ahead of T-Mobile (99.37%) and Orange (99.35%). Plus scored the lowest, though still very high, at 98.78%. In terms of upload success, Play again led with 99.59%, followed by Orange (98.88%), Plus (98.78%), and T-Mobile (98.40%).

Download and Upload Speeds

Differences become more visible in the analysis of application throughput (P90), which reflects real user-experienced speeds. T-Mobile dominated in download speed with 508.97 Mbps—significantly more than Orange (326.63 Mbps) and Play (286.93 Mbps). Plus came last with 150.96 Mbps.

For upload speeds, Play again led with 77.67 Mbps. Orange (61.94 Mbps) and T-Mobile (60.19 Mbps) were close behind, while Plus had the lowest score (52.49 Mbps).

Latency

The average Round Trip Time (RTT) was measured via ping tests (10x 32B PING – Ookla), indicating how quickly a device receives a server response after sending a request. This metric is crucial for services requiring low latency, such as online gaming, video calls, and remote work. Play performed best with an average latency of 35 ms, making it the most responsive network. T-Mobile and Plus both scored 40 ms, indicating good connection quality. Orange recorded the highest latency at 50 ms, which, while still acceptable, may feel less smooth in highly interactive scenarios.

Voice Call Quality in Kuyavian-Pomeranian Voivodeship (2025)

VoLTE

Data on VoLTE voice calls shows that all operators achieved a very high call setup success rate, though call quality and stability varied.

Orange had the best call setup success (99.55%), followed by T-Mobile (99.40%), Play (99.26%), and Plus (99.09%). Though differences are minor, they may impact user experience in marginal coverage areas.

In terms of call stability (Call Drop Rate), Orange performed best (0.64%), followed by Plus (0.83%), T-Mobile (0.94%), and Play, which had the highest rate (1.53%).

For voice quality (MOS – Mean Opinion Score), T-Mobile (4.46) and Play (4.45) ranked highest, indicating very clear audio. Orange scored 4.43, while Plus, still within a good range, came last with 4.24.

The share of very low-quality calls (MOS < 1.6) was lowest for Play (1.03%), followed by T-Mobile (1.56%), Plus (1.98%), and Orange (2.00%).

gOTT Whatsapp 

Voice call quality via WhatsApp (gOTT) in Free Mode showed similar connection success across all networks, but clear differences in audio quality.

Call setup success was high for all, with Play (99.31%) leading, followed by Orange (99.25%), T-Mobile (99.23%), and Plus (99.15%). These minor differences likely have little effect on user experience.

Call stability was also similar, with Play and Plus scoring best (1.30% drop rate), Orange at 1.37%, and T-Mobile at 1.33%.

Audio quality (MOS) showed the largest variation—Play scored highest (4.03), followed by Plus (3.95), T-Mobile (3.90), and Orange (3.89). All were above the acceptable threshold, but Play’s edge may be noticeable in daily use.

Regarding the share of very low-quality calls (MOS < 1.6), Play again led with only 1.15%. T-Mobile (1.45%), Plus (1.36%), and Orange (1.76%) scored slightly worse, though still within acceptable bounds.
