Key Findings

Chunghwa wins the Video Experience award again

With a score of 74.3 on a 100-point scale, Chunghwa holds onto the award for mobile video streaming. The two closest chasing operators were again FarEasTone with a score of 73.3 and Taiwan Mobile with a score of 72.8. Video Experience is based on video streaming tests carried out at scale across mobile networks with real smartphone users.

As speeds increase, Chunghwa's winning Download Speed Experience margin narrows

While the Download Speed Experience of our Chunghwa users increased from 44.2 Mbps in the last report to 58.6 Mbps now, the average speed of our FarEasTone users also rose from 36.8 Mbps to 53.1 Mbps. As a result Chunghwa's victory margin narrowed. Third placed Taiwan Mobile also saw an increase in its Download Speed Experience score from 31 Mbps to 37.4 Mbps.

FarEasTone retains the Upload Speed Experience award

With a score of 12.7 Mbps, the average speed our FarEasTone users saw was slightly higher than Chunghwa's score of 11.9 Mbps and Taiwan Mobile's 10.4 Mbps. Unlike download speed, having a high upload speed makes it easier to share photos or videos on social media or send large office files via email.

Games Experience is jointly won by three operators

Chunghwa, FarEasTone and Taiwan Mobile share the Games Experience award with statistically tied scores of 77.7, 78 and 78.1 on a 100-point scale. All three operators rank as Good (75>85) meaning gameplay experience is generally controllable and most users did ot experience a delay between their actions and a game's response. Since the last report, Chunghwa has joined the previous award holders — FarEasTone and Taiwan Mobile — as a third winner.

Chunghwa wins 4G Coverage Experience, but GT holds the 4G Availability prize

With a score of 9.9 on a ten-point scale, Chunghwa has a very high 4G Coverage Experience result. Chunghwa was the only operator to improve its 4G Coverage Experience result since the previous report. However, when we look at the time our users spent connected to a 4G or better mobile technology, GT wins with 96% slightly ahead of FarEasTone (94.1%), Taiwan Mobile (93.6%) and Chunghwa (91.5%).

Introduction

In this new report on the overall mobile network experience across all Taiwan's mobile users, we are starting to see the impact of 5G services on overall results. While the changes in the awards table are modest, overall average download speeds — Download Speed Experience — have risen on the four operators that have been most aggressive with their 5G offerings. Also, we are seeing early signs of an impact on Games Experience and Upload Speed Experience from 5G as well and this is an area to watch in future reports.

To examine the 5G experience in detail, Opensignal has again published a companion 5G report that examines the experience of users when connecting with 5G technology. In this 5G report, FarEasTone and Chunghwa both win two 5G awards outright, both operators also jointly win a further three 5G awards, while Taiwan Mobile jointly wins one 5G award.

Alongside these 5G awards and overall Opensignal awards, in this report we are also publishing supporting metrics on the overall experience of just 5G users. These results reflect the experience of just 5G users — those users that have both a 5G smartphone and a 5G tariff plan — across all generations of mobile technology, taking into account the proportion of time 5G users spend connected to 3G, 4G and 5G networks.

National Analysis

Video Experience

With a score of 74.3 Chunghwa wins the Video Experience award, slightly ahead of FarEasTone (73.3) and Taiwan Mobile (72.8). All five operators rated as Very Good (65<75) which means users saw generally fast loading times and only occasional stalling but the experience might have been somewhat inconsistent across users or video providers or resolutions.

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 to quantify the overall video experience for each operator on a scale from 0 to 100. The videos tested include a mixture of resolutions and are streamed directly from the world's largest video content providers.

Games Experience

There is a three way tie on Games Experience with Chunghwa, FarEasTone and Taiwan Mobile jointly winning the award. All three winning operators rate as Good (75<85) — this means most users deemed the experience acceptable. Gameplay experience was generally controllable and the user received immediate feedback between their actions and the outcomes in the game. Most users did not experience a delay between their actions and the game's response.

Games Experience quantifies the experience when playing real-time multiplayer mobile games. The approach is built on 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). Multiplayer game genres include: battle royale, example games include PUBG, Garena Freefire, and Fortnite; and MOBA (massive online battle area), an example of which is Arena of Valor.

Voice App Experience

T Star misses out on Voice App Experience as the other four operators jointly win the award. Voice App Experience measures the quality of experience for over-the-top (OTT) voice services — example apps include LINE, WhatsApp, Skype, Facebook Messenger — using a model derived from an International Telecommunication Union (ITU) approach for quantifying overall voice call quality and a series of calibrated technical parameters. This model characterizes the exact relationship between real-world measurements that Opensignal measures at scale from smartphone users and their perceived call quality. Voice App Experience for each operator is calculated on a scale from 0 to 100.

Download Speed Experience

Four of Taiwan's operators have seen 5G services help to boost the overall Download Speed Experience. Our users on those four operators have seen their average download speed increase as follows: Chunghwa's Download Speed Experience score has increased from 44.2 Mbps to 58.6 Mbps, FarEasTone's score has risen from 36.8 Mbps to 53.1 Mbps; Taiwan Mobile's score from 31 Mbps to 37.4 Mbps; and T Star from 22.8 Mbps to 25.3 Mbps now. But GT's score has not risen: it was 17 Mbps six months ago and is 15.4 Mbps now.

Upload Speed Experience

FarEasTone holds onto the Upload Speed Experience award with a score of 12.7 Mbps. Having high average upload speeds helps users to share large photos or videos on social media, connected to virtual private networks (VPNs), or send attachments via email.

While the operators' scores are similar on Upload Speed Experience, there has been some movement since the last report six months ago. Second placed Chunghwa pulled ahead of Taiwan Mobile and increased its lead over its competitor from 0.3 to 1.5 Mbps.

4G Availability

Six percentage points separate the five operators on 4G Availability. GT wins the 4G Availability award with a score of 96%. 4G Availability measures the proportion of time people have a 4G or 5G 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 reflection of the true user experience.

4G Coverage Experience

With a score of 9.9 on a ten-point scale Chunghwa wins the 4G Coverage Experience award again. This is a very high score. In second place, FarEasTone and Taiwan Mobile's scores of 9.6 remained unchanged, as were T Star's score of 9.4 and last placed GT's score of 9.

4G Coverage Experience metric is a measure of how mobile subscribers experience 4G coverage on an operator's network. Measured on a scale of 0-10, it analyzes the locations where customers of a network operator received a 4G signal relative to the locations visited by users of all network operators.

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.
