This marks a notable shift, as AIS — last year’s winner — saw a slight decline from 71.6 points to 71.1, allowing DTAC to take the lead in delivering the best 5G video streaming experience in Thailand.
AIS users experience the best 5G coverage in Thailand
AIS wins outright in both 5G coverage awards. For 5G Availability, our AIS 5G users utilizing an active 5G connection 38.8% of the time. It commands a six percentage point winning margin over both DTAC and TrueMoveH and AIS’ score has improved by nine percentage points since last year's report.
AIS wins 5G Consistent Quality
AIS triumphs for 5G Consistent Quality with a score of 84.6%, beating DTAC by 11 percentage points. This metric measures if the network is sufficient to support common mobile application requirements at a level that is good enough for users to complete various typical demanding tasks on their devices.
AIS leads in regional 5G awards and experience
AIS takes home the most regional awards, winning 32 outright and sharing four more out of 42 available. It sweeps all seven regions for both 5G Upload Experience and 5G Games Experience. In Bangkok Metropolis, our AIS users enjoy the top 5G experience across several key metrics.
5G Experience Awards
Market Overview
Following in line with the 5G section of our previous Thailand Mobile Network Experience report , AIS is the most awarded operator, with six outright wins. DTAC wins one — 5G Video Experience, which leaves TrueMoveH with no wins. AIS earns the title of Best 5G Network, which recognizes operators providing outstanding 5G experiences nationally in key Opensignal metrics.
Following the True/DTAC merger, the combined entity reported 93% nationwide 5G coverage as of February 2025, including over 99% coverage in the Bangkok Metropolitan Area and Eastern Economic Corridor. The company aims to expand its 5G footprint to 98% by the end of 2026, reinforcing its commitment to national-scale network reach.
Thailand’s NBTC is set to hold a multi-band spectrum auction on June 29, 2025, releasing 450MHz across seven bands including 2100MHz and 2300MHz — key for 5G expansion. Major operators like AIS and True are expected to participate as they seek to boost network capacity.
In this report we examine the mobile network experience of the three main mobile network operators in Thailand — AIS, DTAC and TrueMove H — over a period of 90 days starting on February 1, 2025, and ending on May 01, 2025, to see how they fared. Also, we analyze how the 5G experience varies across seven regions of Thailand. We have published a companion Thailand Mobile Network Experience report which analyzes our Thai users’ overall experience across all generations of network technology.
5G Experience
National Analysis
DTAC claims the top spot in 5G Video Experience with a score of 73.1 points gaining a lead of around two points over TrueMove H’s and AIS’ statistically tied scores of 71.0- 71.1 points.
DTAC has taken the lead due to a six point improvement in its score from that seen in the last report. TrueMove H's score has increased by one point while AIS's score decreased by one point.
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.
5G 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
5G Video Experience quantifies the quality of mobile video experienced by Opensignal users on real-world video streams when they were connected to 5G. 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 5G Video Experience, we are directly measuring video streams from end-user devices and using this ITU approach to quantify the video experience observed by our users on each operator’s 5G network 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.
National Analysis
AIS wins the 5G Games Experience again this time around, ahead of TrueMove H's and DTAC's statistically tied scores of 80.1-80.5 points.
DTAC and TrueMove H both show notable improvements, with their scores rising by five and three points respectively. AIS, meanwhile, maintains its strong position, with its score remaining largely unchanged since the previous report.
All operators place in the Good (75-85) category.
A Good (75-85) rating 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 a delay between their actions and the game.
Definitions
5G Games Experience measures how mobile users experience real-time multiplayer mobile gaming on an operator's 5G network. It analyzes how our users’ multiplayer mobile gaming experience was affected by mobile network conditions including latency, packet loss and jitter. 5G Games Experience for each operator is calculated on a scale from 0 to 100.
5G 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 5G Games Experience starts with measuring the end-to-end experience from users’ devices to internet end-points that host real games.
National Analysis
AIS remains the sole winner of 5G Voice App Experience award with a score of 82.8 points on a 100-point scale.
Regardless of their choice of a mobile operator, our Thai users enjoy a Good (80-87) quality of 5G Voice App Experience. This means many users are satisfied but some experience minor quality impairments. For example, clicking sounds or distortion are very rarely present.
Definitions
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. It uses 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. 5G Voice App Experience for each operator is calculated on a scale from 0 to 100.

Coverage
National Analysis
AIS wins the 5G Coverage Experience award with a score of 2.7 points, a lead of less than one point over DTAC and TrueMove H's identical scores of 2.4 points. These two operators share their network infrastructure post-merger.
AIS’ and TrueMove H’s scores have both risen by a single point compared to those seen in the last report, while DTAC gained less than one point.
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.
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
AIS wins the 5G Availability award with a score of 38.8% taking a lead of seven percentage points over second-placed TrueMove H's and DTAC's identical scores of 32.1% These scores reflect the proportion of time our 5G users spend utilizing 5G services on their devices.
All three operators’ 5G Availability scores have improved compared to those seen last time around. Both DTAC and AIS saw an increase of nine percentage points, while TrueMove H followed closely with an eight-point gain.
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.

Consistency
National Analysis
AIS triumphs for 5G Consistent Quality with a score of 84.6%, beating DTAC by 11 percentage points.
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.
Definitions
5G Consistent Quality measures if the 5G 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 5G 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 5G 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.

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.
