Key findings

Telekom Slovenia leads the download speed race

Our Telekom Slovenia users saw the fastest average download speeds of over 40 Mbps, beating their counterparts on second-placed Telemach by about 8 Mbps. A1 and T-2’s scores of around 25 Mbps are statistically tied which is approximately two-thirds of Telekom Slovenia’s score. Telekom Slovenia also won the Upload Speed Experience award. Its users saw average upload speeds of 11.8 Mbps which was at least 2.3 Mbps (24.2%) faster than their counterparts on the other operators’ networks.

After a closely fought contest Telekom Slovenia has come out ahead on Video Experience

All of the Slovenian operators achieved similar scores, with a spread of only 4.1 points between them. Three operators placed in the Excellent (75 or above) category: the award winner, Telekom Slovenia with a score of 78.0; along with T-2 and A1 . Video Experience quantifies users’ perceived quality of video streamed to mobile devices on a scale from 0 to 100 by measuring real-world video streams over an operator's network. The videos tested include a mixture of resolutions and are streamed directly from the world’s largest video content providers.

T-2 and Telekom Slovenia jointly win the Games Experience award

Users enjoyed mobile gaming with the fewest disruptions over T-2 and Telekom Slovenia’s networks with our users recording statistically tied scores of 80.9 and 79.6, respectively, and as a result the two operators have jointly won the Games Experience award. Both T-2 and Telekom Slovenia placed in the Good (75-85) category which means that users found the gameplay to be generally controllable and received immediate feedback between their actions and the outcomes in games. A1 and Telemach , which were statistically tied with each other, placed in the Fair (65-75) category. Opensignal’s Games Experience analyzes how mobile network conditions — including latency, packet loss and jitter — impact the real-time multiplayer mobile gameplay over operators’ networks. It considers multiple genres of multiplayer mobile games to measure the average sensitivity to network conditions.

The best Voice App Experience awards go to T-2 and Telekom Slovenia

Opensignal's Voice App Experience measures the quality of experience for OTT voice services such as WhatsApp, Skype and Facebook Messenger. Calculated on a scale of 0-100, it characterizes the exact relationship between the technical measurements and perceived call quality. In Slovenia, T-2 and Telekom Slovenia jointly won the award in this category due to a statistical tie — with our users seeing scores of 83.5 and 82.2, respectively. The two operators, along with Telemach (80.3), placed in the Good (80-87) category. This means that many users were satisfied but some experienced minor quality impairments.

Telekom Slovenia and Telemach tie for the 4G Availability award, while T-2 is far behind on 4G Coverage Experience

Opensignal uses two indicators to reflect the extent of 4G. 4G Availability shows the average proportion of time that our users were connected to 4G. In this category, our 4G users on Telemach and Telekom Slovenia’s networks spent 94.5% of their time connected to 4G which is significantly ahead of T-2 and A1 which had statistically tied scores of 86.7% and 86.5% respectively. Another indicator — 4G Coverage Experience — analyzes the locations where customers of a network operator received a 4G signal relative to the locations visited by users of all network operators with scores on 0-10 scale. Telekom Slovenia won the 4G Coverage Experience award with an impressive score of 9.7, ahead of A1 (8.9) and Telemach (7.7), while T-2 significantly lagged behind with a score of 1.4.

Introduction

In Opensignal's first mobile network experience report on Slovenia, Telekom Slovenia dominates our awards table with four outright wins and it also jointly won the remaining three awards. T-2 shared the Games Experience and Voice App Experience awards with Telekom Slovenia, while Telemach was a joint winner of the 4G Availability award.

As of April 2021, only Telekom Slovenia, the operator with the largest number of subscribers in the market, had a live 5G commercial service. The operator launched its 5G network in July 2020 using the 2.6 GHz band – and claims to have rolled out coverage across approximately 25% of the population during the launch and reached network coverage of 32%, according to information retrieved from its official website in April 2021. Other operators have performed 5G trials but have yet to deploy 5G on a broad commercial scale. There will be more momentum around 5G, once national regulator AKOS completes the much anticipated 5G multi-band spectrum auction and announces the winners in mid-2021. This auction will allocate a range of frequency bands from 700 MHz to 26 GHz. In February 2021 AKOS received four applications for this tender although it did not reveal the bidders.

Slovenia’s telecoms sector experienced a heavy surge in traffic in 2020 due to the COVID-19 pandemic. Telekom Slovenia recorded a doubling of data transfer, Telemach reported a 30 percent increase in mobile data traffic, while T-2 similarly reported mobile data transfer doubling in 2020. Slovenian customers will likely benefit from an improved mobile internet experience as imminent 5G upgrades mean operators are able to deploy more spectrum for mobile services.

Our results in this report are based on measurements collected across all major mobile operators in Slovenia – A1, T-2, Telekom Slovenia and Telemach – over the period of 90 days between December 1, 2020 and February 28, 2021. 5G measurements contributed to the overall scores.

Opensignal measures the real-world experience of consumers on mobile networks in the places they live, work and travel.

We continually adapt our methodology to best represent the true experience of smartphone users. Therefore, comparisons of the results to past reports should be considered indicative only.

For every metric we calculate statistical confidence intervals indicated on our graphs. When confidence intervals overlap, our measured results are too close to declare a winner. In those cases, we show a statistical draw. For this reason, some metrics have multiple winners.

In our bar graphs we represent confidence intervals as boundaries on either sides of graph bars. In our supporting-metric charts we show confidence intervals as +/- numerical values.
