The best mobile multiplayer gaming experience is with Chunghwa
Chunghwa is the outright winner in both Games Experience and 5G Games Experience. This marks the second time in a row that Chunghwa has claimed both titles among Taiwanese operators.
Chunghwa dominates the 5G Experience awards
Chunghwa is the top Taiwanese operator in 5G Experience. Chunghwa wins all of the awards in the 5G Experience section, sharing victory only in 5G Voice App Experience.
Chunghwa wins both 5G Coverage and 5G Availability
Chunghwa takes home the top spot in both 5G Coverage and 5G Availability. It wins the former with a score of 7.2 points on a 10-point scale and the latter with a score of 33.8%.
Taiwan Mobile maintains its hold on Consistent Quality
Taiwan Mobile wins the Consistent Quality award for the second report in a row. It wins this time with a score of 84.5% — an improvement over its previous score of 83.1%.This metric measures if the network is sufficient to support common mobile application requirements at a level that is ‘good enough’ for users to maintain (or complete) various typical demanding tasks on their devices.
Mobile Experience Awards
Market Overview
As in our previous Taiwan Mobile Network Experience report, Chunghwa is the most awarded operator. Chunghwa wins 10 awards outright and shares victory in an additional four awards. Taiwan Mobile follows with three shared awards and is the sole winner for Consistent Quality. Rounding out the three national operators, FarEasTone finishes with three joint victories.
This is Opensignal’s second Taiwan Mobile Network Experience report following the market’s merger activity in December 2023. FarEasTone merged with Asia Pacific Telecom’s GT brand, while Taiwan Mobile merged with T Star.
On June 30, 2024, Chunghwa, FarEasTone, and Taiwan Mobile shut down their 3G networks.
Taiwan placed highly in several categories in Opensignal’s APAC Mobile Network Experience report published in September. Taiwan came in first for Consistent Quality among all APAC nations. Consistent Quality measures if the network is sufficient to support common mobile application requirements at a level that is ‘good enough’ for users to maintain (or complete) various typical tasks on their devices. In addition to this top finish, Taiwan placed second for Reliability Experience and Video Experience, and third for Download Speed Experience.
In this report we examine the mobile network experience of the three main mobile network operators in Taiwan — Chunghwa, FarEasTone, and Taiwan Mobile — over a period of 90 days starting on August 1, 2024, and ending on October 29, 2024, to see how they fared.
Overall Experience
National Analysis
Chunghwa and Taiwan Mobile are joint winners with statistically tied scores of 71.6-72 points on a 100-point scale.
Our Taiwanese users on all three mobile operators enjoy Very Good (68-78) on-demand video services. On average, they are 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.
- 4G Video Experience: The average Video Experience of Opensignal users on an operator's 4G network.
- 3G Video Experience: The average Video Experience of Opensignal users on an operator’s 3G network.
National Analysis
Chunghwa wins the Games Experience award outright for the second report in a row. It does so with a score of 79.6 points on a 100-point scale.
All Taiwanese operators place in the Good (75-85) category. This means that most users deem the experience acceptable. The gameplay experience is generally controllable and the user receives immediate feedback between their actions and the outcomes in the game. Most users do not experience delay between their actions and the game.
Definitions
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.
- 4G Games Experience: The average Games Experience of Opensignal users on an operator's 4G network.
- 3G Games Experience: The average Games Experience of Opensignal users on an operator's 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO) network.
National Analysis
Chunghwa and FarEasTone are joint winners of Voice App Experience with statistically tied scores of 80.4 and 80.2 points on a 100-point scale, respectively. The two providers finish just ahead of third placed Taiwan Mobile, though all three place in the Good (80-87) category. This means that many of our Taiwanese users were satisfied, but some experienced some minor quality impairments.
Definitions
Opensignal's Voice App Experience measures the quality of experience for over-the-top (OTT) voice services — mobile voice apps such as WhatsApp, Skype and Facebook Messenger — using a model derived from the 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 the technical measurements and perceived call quality. Voice App Experience for each operator is calculated on a scale from 0 to 100.
In addition to Voice App Experience, we report on the following metrics related to voice app experience:
- 5G Voice App Experience: The average Voice App Experience of Opensignal users when they were connected to an operator’s 5G network.
- Voice App Experience – 5G Users: The average Voice App 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 voice app experience along with the availability of each technology.
- 4G Voice App Experience: The average Voice App Experience of Opensignal users on an operator's 4G network.
- 3G Voice App Experience: The average Voice App Experience of Opensignal users on an operator's 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO) network.
National Analysis
Once again, Chunghwa is the outright winner of the Download Speed Experience Award. The operator’s score of 106.9Mbps is 87% faster than what our users on second placed FarEasTone experience. Chunghwa’s lead has increased from the previous report, as its score has risen by 13Mbps.
Definitions
Measured in Mbps, Download Speed Experience represents the typical everyday speeds a user experiences across an operator’s mobile data networks.
In addition to Download Speed Experience, we report on the following metrics related to download speeds:
- 5G Download Speed: The average download speed observed by Opensignal users with active 5G connections.
- Download Speed Experience – 5G Users: The average download speeds experienced by Opensignal users with a 5G device and a 5G subscription across an operator’s networks. It factors in 2G, 3G, 4G, and 5G download speeds along with the availability of each technology.
- 4G Download Speed: The average downlink speed observed by Opensignal users when they were connected to 4G.
- 3G Download Speed: The average downlink speed observed by Opensignal users when they were connected to 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO).
National Analysis
Chunghwa continues to be the outright winner of the Upload Speed Experience Award. The operator does so this time with a score of 17.5Mbps and a winning margin of 5.1Mbps over second placed FarEasTone.
Definitions
Upload Speed Experience measures the average upload speeds for each operator observed by our users across their mobile data networks. Typically upload speeds are slower than download speeds, as current mobile broadband technologies focus resources on providing the best possible download speed for users consuming content on their devices. As mobile internet trends move away from downloading content to creating content and supporting real-time communications services, upload speeds are becoming more vital and new technologies are emerging that boost upstream capacity.
In addition to Upload Speed Experience, we report on five supporting metrics related to upload speeds:
- 5G Upload Speed: The average upload speed observed by Opensignal users with active 5G connections.
- Upload Speed Experience – 5G Users: The average upload speeds experienced by Opensignal users with a 5G device and a 5G subscription across an operator’s networks. It factors in 2G, 3G, 4G, and 5G upload speeds along with the availability of each technology.
- 4G Upload Speed: The average uplink speed observed by Opensignal users when they were connected to 4G.
- 3G Upload Speed: The average uplink speed observed by Opensignal users when they were connected to 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO).

National Analysis
Chunghwa retains its 5G Download Speed title with an exceptional score of 346.7Mbps. The operator’s score is 71% faster than that registered by second placed FarEasTone. Like our Chunghwa users, our Taiwan Mobile users saw an increase in their 5G Download Speed scores. FarEasTone’s score, however, remains statistically unchanged.
Definitions
5G Download Speed shows the average download speed experienced by Opensignal users across an operator’s 5G network. 5G Download Speed for each operator is calculated in Mbps (Megabits per second).
National Analysis
Chunghwa continues to set the pace in 5G Upload Speed, winning this time with a score of 54Mbps.

Coverage
National Analysis
Chunghwa wins the Coverage Experience award for the fourth consecutive report, doing so this time with a repeated score of 9.3 points on a 10-point scale. FarEastTone’s and Taiwan Mobile’s scores have improved slightly from those seen in the last report.
Definitions
The Opensignal Coverage Experience metric measures the extent of mobile networks in the places people live, work and travel. The metric represents the experience users receive as they travel around areas where they would reasonably expect to find coverage.
Traditional coverage metrics typically estimate either a percentage of land area covered, or a percentage of population covered; often neither will be an accurate measurement of the true user expectation and experience. In many markets there are areas where neither population density nor geographic area reflect the importance of coverage to users. For example, in a large mountain range most users will not expect coverage in the wilderness, but poor coverage in the relatively small area of a ski resort is critical for the enjoyment of a holiday. Estimates based purely on population give undue significance to coverage in the most densely populated areas.
Coverage Experience measures geographic coverage of populated areas and therefore more accurately reflects the coverage expectations and experience of typical users. It can give a result that is somewhat different to traditional estimates based on either geographic or population measures. The metric uses a scale from 0 to 10.
National Analysis
Like the Coverage Experience award, Chunghwa wins in 5G Coverage Experience for the fourth time running with a score of 7.2 points on a 10-point scale. All three Taiwanese operators’ scores have improved from those seen in the last report.

5G Coverage Experience shows the proportion of places Opensignal users with a 5G device and a 5G subscription had an active 5G connection.
National Analysis
FarEasTone and Taiwan Mobile are joint winners for Availability, with statistically tied scores of 99.2-99.3%. Chunghwa trails with a score of 98.9%. Availability scores represent the proportion of time Opensignal users spend with a 5G, 4G or 3G mobile signal.
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.
National Analysis
Chunghwa dethrones FarEasTone to win the 5G Availability award with a score of 33.8%. This means our 5G Chunghwa users spend over a third of their time with an active 5G connection.
All three operators’ scores have increased compared to the last report.

Consistency
National Analysis
Taiwan Mobile wins outright in Consistent Quality for the second report in a row — this time with a score of 84.5%, beating Chunghwa by 1.3 percentage points. All three operators’ scores have risen since the previous report, with FarEasTone seeing the biggest increase of 3.4 percentage points.
Definitions
Consistent Quality measures if the network is sufficient to support common mobile application requirements at a level that is ‘good enough’ for users to maintain (or complete) various typical tasks on their devices.
We combine different experience indicators such as download speed, upload speed, latency, jitter, packet discard, and time to first byte to calculate Consistent Quality. These components are evaluated against thresholds recommended by various more demanding common applications used for a range of common tasks.
To calculate the metric value, the proportion of tests that pass the requirements of Consistent Quality is multiplied by the test success ratio, which is the proportion of completed tests to all tests conducted. Tests that pass indicate that activities such as video calling, uploading an image to social media, or using smart home applications will be possible without noticeable lag or slowdown.
National Analysis
For the second report in a row, Chunghwa and Taiwan Mobile share the honors in Reliability Experience. With statistically tied scores of 905-909 points on a 100-1000-point scale, the two joint winners finish comfortably ahead of FarEasTone’s 871 points.
Definitions
Opensignal’s Reliability Experience measures the ability of Opensignal users to connect to and successfully complete (basic) tasks on communication service providers’ (CSP) networks. It analyzes how much Opensignal users’ experience is affected by the radio access and core network, along with issues that prevent them from connecting to the internet even if they have a connection to their CSP’s network. It also factors in users’ ability to successfully use lower performance applications including SD video, over-the-top voice calls and web browsing.

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.
