French benchmarking firm nPerf has today published the results from an unusual new study, which compared the fastest average mobile broadband download speeds (4G and 5G) of 20 countries with a similar size (land area) to Poland. The results saw the United Kingdom rank 3rd with an average speed of 105.8Mbps.
nPerf’s latest study was based on masses of tests carried out – between January and the end of April 2026 – by users of the speed testing tools on both nPerf’s website and via their dedicated mobile testing apps for Android and iOS. But we don’t get any hard stats on the sample sizes or structure.
Over the period studied, Poland stands out with an average mobile download speed of 109.9Mbps, the highest in the group. This result places it ahead of Germany (106.7 Mbps) and the United Kingdom (105.8 Mbps) in 2nd and 3rd place, respectively. At the other end of the table, Paraguay (16.8 Mbps) has a speed nearly 6.5 times slower than Poland and ranked slowest overall in 20th.
Analysis of the data also reveals some notable differences between continents. Europe dominates the top of the ranking with five countries in the top seven (Poland, Germany, United Kingdom, Spain, Italy), while Asia is represented by Vietnam, Thailand (86.7 Mbps), Cambodia, and Laos (30.7 Mbps). Africa, with Morocco, Madagascar, Tunisia, Senegal, Ivory Coast (22.6 Mbps), and Kenya (21.2 Mbps), generally shows performance below the group average (68.5Mbps), with Morocco as an exception.
Overall, this was a fairly narrow study and one that only examined average download speeds, which doesn’t really tell us all that much about the wider issues of mobile connectivity and coverage. Make of it what you will.
