Although the Swietokrzyskie Voivodeship is not among the largest in Poland, its residents – like the rest of the country – increasingly rely on fast and stable access to mobile services. A reliable internet connection today is more than just a convenience; it’s a necessity – whether for remote work, online learning, or streaming your favorite series. That’s why we examined how mobile operators are performing in this part of the country.

The data was collected using the Drive Test method, which allows for an objective comparison of call quality and data transmission in diverse terrain conditions – from city centers to smaller towns and the roads in between. These are not marketing figures – they are real, field-tested metrics.

So, which provider delivers the fastest mobile internet? Where can users expect the lowest latency and the best voice quality? Here are the latest results from RFBENCHMARK measurements.

14 professional devices were used during the testing, including the latest Samsung S24 Ultra smartphones and advanced signal analyzers like PCTEL GFlex and IBFlex. This setup enabled a precise assessment of services offered by Poland’s four largest mobile network operators. The tests covered both voice calls (VoLTE and WhatsApp) and 5G data transmission – measuring download and upload speeds, latency (ping), and video streaming quality. These results reflect real user experiences in a variety of everyday scenarios.

Mobile Internet Speed in Swietokrzyskie (2025)

File Transfer Efficiency – Download and Upload

In the file download success test, Play took the lead with a 99.43% success rate for 10-second transfers. Plus followed closely with 99.29%, while Orange achieved 98.76%. T-Mobile, though slightly lower at 97.40%, still maintained a solid performance.

As for uploads, Play remained in first place with 99.28%, demonstrating high reliability. Orange ranked second (98.89%), with Plus just behind at 98.71%. T-Mobile came in last with 96.67%, still a respectable result but lower than its competitors.

Download and Upload Speed

T-Mobile was the clear leader in download speed, reaching 505.18 Mbps. This was the highest result across the board, indicating the operator’s network in Swietokrzyskie has significant capacity. Orange followed with 423.33 Mbps, while Play delivered a notably lower 310.80 Mbps. Plus performed weakest, with only 199.49 Mbps.

When it came to upload speeds, the differences were smaller yet still notable. T-Mobile again led the field with 71.27 Mbps, followed by Orange (69.76 Mbps) and Play (68.94 Mbps). Plus came last with 55.06 Mbps. All results offer decent support for cloud services and large file uploads, though more demanding users may feel the impact.

Latency

The RTT (Round Trip Time) indicator reflects the time needed to send a small data packet from a device to a server and back. It is a crucial parameter for users of applications that require rapid responsiveness – such as video conferencing, online gaming, or VoIP services. The lower the RTT, the more responsive the network.

In the Swietokrzyskie Voivodeship, Play achieved the best result, with an average latency of 29 ms, confirming the smooth performance of its services. Plus came next with 40 ms, followed by Orange at 45 ms. T-Mobile recorded the highest response time of 49 ms, which is still within acceptable limits but may be noticeable in more demanding use cases.

While the differences in latency may seem small, they can significantly impact the overall user experience, especially in situations where every millisecond counts.

Voice Call Quality in Swietokrzyskie (2025)

VoLTE

VoLTE (Voice over LTE) enables high-quality voice calls using the 4G network, which results in faster call setup and better sound without switching to older technologies.

In Call Setup Success Rate, Orange topped the chart at 99.69%, followed by T-Mobile (99.49%) and Play (99.22%). Plus trailed slightly at 98.58%, but still within a very good range.

Greater variation was seen in Call Drop Rate. T-Mobile performed best with just 0.20% dropped calls. Orange followed with 0.31%, while Play (1.34%) and Plus (1.66%) showed weaker performance in this category.

For audio quality (measured by MOS), Play scored highest with 4.48, just ahead of Orange (4.46) and T-Mobile (4.45). Plus came in lower with 4.12, which may indicate less clarity in voice calls.

The Audio Quality MOS < 1.6 indicator, showing the share of very poor-quality calls, was lowest (best) for Play at 0.95%. Plus had the highest percentage of low-quality calls at 2.57%, in line with its overall lower audio rating.
