Chungwha wins 13 of 16 possible awards, with ten outright and three joint wins. This makes Chungwha the most awarded Taiwanese operator in the most recent Mobile Network Experience Awards.
Chunghwa wins both the Reliability Experience and Consistent Quality awards. Chunghwa had won both awards outright in the previous June 2025 Mobile Network Experience Awards as well.
Chunghwa wins all four speed experience awards: Download Speed Experience, Upload Speed Experience, 5G Download Speed Experience and 5G Upload Speed Experience outright.
Taiwan Mobile wins the overall Video Experience award with a score of 73.2 points on a 100-point scale. In previous reports, Taiwan Mobile jointly won the award but now Taiwan Mobile has the sole claim on the award. Taiwan Mobile is a joint winner of 5G Video Experience award
FarEasTone wins the 5G Availability award with a score of 76.5%, meaning Opensignal users with a 5G device and a 5G subscription on FarEasTone’s network had a 5G connection 76.5% of the time, whether or not it was actively used. Taiwan Mobile finished second with a score of 73.4%. Opensignal has revised the 5G Availability metric, which is now defined as the proportion of time Opensignal users with a 5G device and a 5G subscription had a 5G connection, whether or not it was actively used.
Taiwan Mobile, Chunghwa Telecom and FarEasTone share awards for Time-On-Network and 5G Voice App Experience highlighting Taiwan’s strong mobile networks.
Chunghwa wins 13 of 16 total awards to remain the most awarded operator in Taiwan, with ten outright wins and three joint wins. Chunghwa has its sights set on 6G. A six-year, near billion dollar (US) alliance of over 50 companies has been formed to focus on the development of 6G, led by Chunghwa chairman Chien Chih-cheng. The alliance, named the Taiwan NextGen Communications Alliance, consists of companies with many varied focuses and telecom experts.
The move to 5G from 4G has continued since the launch of 5G in 2020. In early November, both Taiwan Mobile and FarEasTone stopped offering 4G unlimited data through retail in an effort to encourage more consumers to upgrade to 5G plans. This move prompted some concern from legislators from multiple parties due to the higher prices of 5G plans. The Ministry of Digital Affairs has also been accelerating the use of private 5G and dedicated spectrum bands to benefit private enterprise in Taiwan as well as developing energy-efficient 5G O-RAN private networks. Both Chunghwa and FarEasTone have also put their focus on satellite. Chunghwa obtained a Low Earth Orbit license in June 2025 and a Medium Earth Orbit license in November 2025. FarEasTone has been reportedly planning a Low Earth Orbit launch of its own in partnership with Project Kuiper.
In this Taiwan Mobile Network Experience report, Opensignal introduces a revised 5G Availability metric, which defines the proportion of time Opensignal users with a 5G device and a 5G subscription had a 5G connection, whether or not it was actively used. Previously, the metric showed the proportion of time Opensignal users with a 5G device and a 5G subscription utilized an active 5G connection — which is now reflected by Time on 5G. Also, our Availability metric changes its name to Time on Network to align with methodological updates in other metrics.
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, 2025, and ending on October 29, 2025, to see how they fared.
Taiwan Mobile now wins the Video Experience award outright with a score of 73.2 points on a 100-point scale and a lead of around one point over second-placed FarEasTone's and Chunghwa's statistically tied scores of 72.5-72.6 points.
All operators place in the Very Good (68-78) category.
A Very Good (68-78) rating means that 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.
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:
Chunghwa again takes home the Games Experience award outright with a score of 86.5 points on a 100-point scale and a lead of around one point over second-placed FarEasTone's and Taiwan Mobile's statistically tied scores of 85.5-85.6 points.
All operators place in the Excellent (85 or above) category.
An Excellent (85 or above) rating means that the vast majority of users deem this network experience acceptable. Nearly all users feel like they have control over the game and they receive immediate feedback on their actions. There is not a noticeable delay in almost all cases.
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:
Chunghwa retains the Voice App Experience award with a score of 82.3 points on a 100-point scale and a lead of less than one point over second-placed FarEasTone's 82 points and Taiwan Mobile’s 81.5 points.
All operators place in the Good (80-87) category.
A Good (80-87) rating means that many users are satisfied. Minor quality impairments are experienced by some users. Sometimes the background is not quite clear, it could be either hazy or not loud enough. Clicking sounds or distortion are very rarely present.
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:
Chunghwa again claims the Download Speed Experience award outright with a score of 100.1Mbps and a lead of 29Mbps over second-placed FarEasTone's 71.2Mbps, followed by Taiwan Mobile’s 69.9Mbps.
Taiwan Mobile and FarEasTone both saw their scores rise by 2Mbps. Chunghwa improved by 1Mbps.
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:
Chunghwa again wins the Upload Speed Experience award outright with a score of 16.1Mbps and a lead of around 2Mbps over second-placed FarEasTone's and Taiwan Mobile's statistically tied scores of 13.7-13.8Mbps.
Taiwan Mobile and FarEasTone improved by 1Mbps each.
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:
In this report, FarEasTone and Taiwan Mobile remain joint winners of the 5G Video Experience award with statistically tied scores of 77.3-77.5 points on a 100-point scale and a lead of around less than one point over third-placed Chunghwa's 77 points.

While Chunghwa was the sole winner of this award in the last report, now all three operators share the 5G Voice App Experience award with statistically tied scores of 83.9-84.2 points on a 100-point scale.
All operators place in the Good (80-87) category.
A Good (80-87) rating means that many users are satisfied. Minor quality impairments are experienced by some users. Sometimes the background is not quite clear, it could be either hazy or not loud enough. Clicking sounds or distortion are very rarely present.
5G Voice App Experience quantifies the experience of Opensignal users when using over-the-top voice apps — such as WhatsApp, Skype and Facebook Messenger — on an operator’s 5G network.

Chunghwa again wins the 5G Download Speed award outright with a score of 279.9Mbps and a lead of 83Mbps over second-placed FarEasTone's 196.6Mbps.
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).
Chunghwa again wins the 5G Upload Speed award outright with a score of 37.9Mbps and a lead of 8Mbps over second-placed FarEasTone's 30.2Mbps.
5G Upload Speed measures the average upload speeds experienced by Opensignal users across an operator’s 5G network. 5G Upload Speed for each operator is calculated in Mbps (Megabits per second).
Chunghwa again wins the Coverage Experience award outright with a score of 9.3 points on a 10-point scale and a lead of one point over second-placed FarEasTone's and Taiwan Mobile's identical scores of 8.7 points.
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.
Chunghwa again wins the 5G Coverage Experience award outright with a score of 7.5 points on a 10-point scale and a lead of one point over second-placed FarEasTone's 6.6 points. Taiwan Mobile comes third with a score of 6.2 points.

5G Coverage Experience shows the proportion of places Opensignal users with a 5G device and a 5G subscription had an active 5G connection.
All three operators remain locked in a statistical tie for the Availability award with scores of 99.3-99.4%. These figures represents the proportion of time Opensignal users spend connected to a 5G, 4G, or 3G mobile signal.
Our time on network and availability metrics are not measures 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 time on network 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 time on network and availability metrics take a user-centric, time-based approach that complements the user-centric and geographical-based methodology used by our reach metrics.
Time on Network shows the proportion of time all Opensignal users on an operator’s network had either a 3G, 4G or 5G connection.
FarEasTone now wins the 5G Availability award outright with a score of 76.5%, which reflects the proportion of time Opensignal users with a 5G device and a 5G subscription has a 5G connection, whether or not it was actively used.

Chunghwa remains the sole winner of the Consistent Quality award with a score of 82.1% and a lead of one percentage point over second-placed Taiwan Mobile's 80.9%. FarEasTone comes third with a score of 74.9%.
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. It assesses a number of experience indicators such as download speed, upload speed, latency, jitter, packet loss, and time to first byte.
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 throughput, upload throughput, 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.
Chunghwa defends the Reliability Experience award outright with a score of 924 points on a 100-1000 point scale and a lead of 12 points over second-placed Taiwan Mobile's 912 points. FarEasTone comes third with a score of 873 points.
Opensignal’s Reliability Experience measures the ability of our users to connect to and successfully complete (basic) tasks on operators’ networks. It consists of the following components:
% time connected — The proportion of time Opensignal users can successfully connect to a mobile network
Data Connectivity — the proportion of time when the network is available and the device can connect to the internet
Task completion — whether tasks initiated by the user’s device are completed
Sufficiency — The probability that (basic) tasks will be executed sufficiently well for the user
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.

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.
Why confidence intervals are vital in analyzing mobile network experience
