Greece is recording high performance in terms of the development of 5G Standalone (5G SA), thanks to the investment choices of OTE, however, the same is not true with the use of this new mobile telephony network.
According to the data of the new international report, for the fourth quarter of 2025, “A Global Reality Check on 5G SA and 5G Advanced”, by Ookla and Omdia, one of the most important telecommunications network measurement and analysis organizations in the global market, Greece recorded an average data download speed of 489 Mbps on 5G SA networks.
This performance ranked the country among the top internationally, ahead of major European markets such as Germany, France and the United Kingdom.
The report attributed this image mainly to OTE, which has developed 5G SA on a commercial scale and concentrates the vast majority of measurements on this network.
For comparison purposes, it should be noted that the average speed in Non Standalone 5G networks in Greece is 162 Mbps, which highlights the performance difference offered by 5G SA.
However, despite the high performance, Greece, like the rest of Europe, is still in the early stages of mass use of 5G Standalone. The percentage of measurements carried out on full 5G is 3.9%, up from 1.9% a year earlier, but remains low.
In other words, the advanced network exists, but the majority of users continue to use older technology, either due to devices or pricing options.
Performance
The report attributed the high Greek performance to OTE’s extensive investments in the new generation network, as well as the wide use of the medium frequency spectrum (3.5 GHz) which was awarded to mobile companies earlier than many other countries.
In addition to speeds, 5G Standalone also offers an improvement in network response time (latency). In Greece, the average delay is reduced from 38 milliseconds in 5G networks to 35 milliseconds in 5G SA.
As noted, such improvements do not depend only on the antenna or the radio network, but also on investments in the “back end” of the network, in optical fibers, data centers and international interconnections, where OTE also has a significant lead.
At the European level, the use of 5G Standalone remains limited, at 2.8%, although it has more than doubled in a year. Europe still lags significantly behind North America and Asia, where countries such as China and South Korea have moved towards mass adoption.
The problem in Europe is not technical, but mainly commercial and institutional, the Report pointed out, as the transition of users to full 5G is delayed by pricing and regulatory factors.
The report cited Spain as an example of a country where public incentives and political support have contributed to the faster adoption of 5G Standalone by users, even if the absolute performance is not the highest. Spain showed a lower average speed (332 Mbps), compared to Greece, but a clearly higher use of 5G SA, with a percentage of 8.3%.
5G Standalone is the “pure” form of 5G, without technical dependence on older 4G networks and is considered critical infrastructure for higher speeds, better response and new digital services, while it does not only concern mobile phones. It is considered a key digital infrastructure for the next phase of the economy, as it allows the network to function not simply as a “data pipe”, but as a platform on which new services and business models can be built.
