Key Findings
HT pulls ahead of its competitors for 5G Download Speed
In the previous report, all three Croatian operators were joint winners for 5G Download Speed. However, while A1’s and Telemach’s scores remain statistically unchanged, HT breaks out of the statistical tie due to a stunning boost of 47Mbps (18.9%) and takes home the 5G Download Speed award. Our HT users enjoy average 5G download speeds clocking in at nearly 300Mbps — around 98.8Mbps faster than what our users on statistically tied A1 and Telemach experience.
Telemach seizes both consistency awards outright
Telemach snatches Excellent Consistent Quality away from the previous sole winner A1 and claims it outright, with a score of 85.2%, due to an increase of six percentage points. The operator also breaks out of a statistical tie it was in with A1 for Core Consistent Quality, and wins the award outright with a score of 93.1%, due to a 2.4-percentage point rise in its score.
HT takes the top spot for 5G Upload Speed
On top of 5G Download Speed, HT wins the other 5G speed award outright — 5G Upload Speed, with a score of 41.9Mbps. HT breaks out of the statistical tie it was in with Telemach for the award, thanks to a remarkable increase of 11.2Mbps — more than a third faster than in the previous report — and as a result, commands an impressive lead over second-placed Telemach of nearly 10Mbps.
Telemach claims 5G Availability all to itself
Our 5G users on Telemach’s network spend 30.5% of their time with an active 5G connection. This is the best result in Croatia, ensuring Telemach’s outright win for 5G Availability. Our Telemach users spend nearly twice as much time connected to 5G networks as their HT peers — and more than three times as much time as those on A1’s network.
Our users in Croatia see the fastest overall speeds on HT’s and Telemach’s networks
Once again, HT and Telemach share the winners’ podium for both overall speed awards — Download Speed Experience and Upload Speed Experience. Both operators jointly win Download Speed with scores in the 62.5-65.1Mbps range, while A1 brings up the rear, with a score of 44.7Mbps. Users on both HT and Telemach enjoy 8.8Mbps and 10.4Mbps faster average download speeds, compared to the previous report, while A1’s score remains statistically unchanged. HT and Telemach also jointly win Upload Speed Experience, with scores of 14.8-15.4Mbps — all operators observe increases in their scores, ranging from 2.2Mbps for HT to 2.7Mbps for A1.
Mobile Experience Awards
Market Overview
We observe several changes in the awards table in the latest Croatia Mobile Network Experience report. For the first time in Opensignal’s mobile network experience reports, Telemach wins both consistency awards — Excellent Consistent Quality and Core Consistent Quality — outright, while also claiming 5G Availability all to itself. HT pulls ahead of its competitors for both 5G speed awards and is now the sole winner of 5G Download Speed and 5G Upload Speed.
Overall, HT and Telemach win 11 out of 14 available awards each — including their two and three outright wins, respectively. Meanwhile, A1 ends with six awards, down from one outright win and eight joint wins seen in the previous report.
The Croatian Postal & Electronic Communications Agency (HAKOM) has finalized the renewal spectrum auction, raising a total of €339 million ($372 million) — more than twice the reserve price of €155 million ($170 million). A1, HT, and Telemach all won 15-year-long licenses (with an option to extend for a further five years) in the 800MHz, 900MHz, 1800MHz, 2100MHz, and 2.6GHz bands.
This secures the continuity of mobile networks’ operations, as the existing concessions in these bands are to expire in 2024. The winners must deliver mobile services to 99.4% of Croatia’s population by the end of 2029, with a minimum receiving signal level of -110dBm. HAKOM re-auctioned spectrum in the 3.5GHz band, which went unsold during the 2021 auction, at a regional level to facilitate opportunities for regional operators — with Digicom and Markoja ending as licence winners.
Our results in this report are based on measurements collected across all major mobile operators in Croatia – A1, HT, and Telemach – over the period of 90 days between December 1, 2022 and February 28, 2023, to see how they fared.
Overall Experience
National Analysis
All Croatian operators remain joint winners for Video Experience with scores in the 68.5-70.6 points range. They all rate as Very Good (68-78), which means our users are, on average, able to stream video at 1080p or better with satisfactory loading times and little stalling.
Video Experience scores account for adaptive bitrate streaming (ABR), a technology that allows Opensignal to accurately represent users’ real video experience including video streams up to 4K quality.
Definitions
Opensignal’s Video Experience quantifies the quality of video streamed to mobile devices by measuring real-world video streams over an operator's networks. The metric is based on an International Telecommunication Union (ITU) approach, built upon detailed studies which have derived a relationship between technical parameters, including picture quality, video loading time and stall rate, with the perceived video experience as reported by real people. To calculate video experience, we are directly measuring video streams from end-user devices and using this ITU approach to quantify the overall video experience for each operator on a scale from 0 to 100. The videos tested include a mixture of resolutions — including Full HD (FHD) and 4K / Ultra HD (UHD) — and are streamed directly from the world’s largest video content providers.
In addition to Video Experience, we report on the following metrics related to video experience:
- 5G Video Experience: The average Video Experience of Opensignal users when they were connected to an operator’s 5G network.
- Video Experience – 5G Users: The average Video Experience of Opensignal users with a 5G device and a 5G subscription across an operator's networks. It factors in 2G, 3G, 4G and 5G video experience along with the availability of each technology.

Opensignal’s Games Experience measures how mobile users experience real-time multiplayer mobile gaming on an operator’s network. Measured on a scale of 0-100, it analyzes how our users’ multiplayer mobile gaming experience is affected by mobile network conditions including latency, packet loss and jitter.
Games Experience quantifies the experience when playing real-time multiplayer mobile games on mobile devices connected to servers located around the world. The approach is built on several years of research quantifying the relationship between technical network parameters and the gaming experience as reported by real mobile users. These parameters include latency (round trip time), jitter (variability of latency) and packet loss (the proportion of data packets that never reach their destination). Additionally, it considers multiple genres of multiplayer mobile games to measure the average sensitivity to network conditions. The games tested include some of the most popular real-time multiplayer mobile games (such as Fortnite, Pro Evolution Soccer and Arena of Valor) played around the world.
Calculating Games Experience starts with measuring the end-to-end experience from users’ devices to internet end-points that host real games. The score is then measured on a scale from 0 to 100.
In addition to Games Experience, we report on the following metrics related to games experience:
- 5G Games Experience: The average Games Experience of Opensignal users when they were connected to an operator’s 5G network.
- Games Experience – 5G Users: The average Games Experience of Opensignal users with a 5G device and a 5G subscription across an operator's networks. It factors in 2G, 3G, 4G and 5G games experience along with the availability of each technology.

National Analysis
A1 slips off the winners’ podium for Availability, leaving HT and Telemach as joint winners with statistically tied scores of 97.4-98.4%. These scores reflect the percentage of time our Croatian users connect to 3G or better services.
Definitions
Our availability metrics are not a measure of a network’s geographical extent. They won’t tell you whether you are likely to get a signal if you plan to visit a remote rural or nearly uninhabited region. Instead, they measure what proportion of time people have a network connection, in the places they most commonly frequent — something often missed by traditional coverage metrics. Looking at when users have a connection rather than where, provides us with a more precise reflection of the true user experience.
We also keep track of the instances that leave mobile users most frustrated: when there is no signal to connect to at all. The most common dead zones users struggle with occur indoors. As most of our availability data is collected indoors (as that’s where users spend most of their time), we’re particularly astute at detecting areas of zero signal.
Our availability metrics take a user-centric, time-based approach that complements the user-centric and geographical-based methodology used by our reach metrics.
Availability shows the proportion of time all Opensignal users on an operator’s network had either a 3G, 4G or 5G connection.
The coverage maps show the locations where we received measurements from users connecting with 3G or better mobile service. Each map provides an indication of the areas in which it is possible to obtain mobile service from that mobile operator.
National Analysis
Our 5G users on Telemach’s network spend 30.5% of their time with an active 5G connection — which gives Telemach an outright win for 5G Availability. Our Telemach users spend nearly twice as much time connected to 5G networks as their HT peers (15.4%) — and more than three times as much time as those on A1’s network (10%).

Confidence Intervals
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 operator 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.
