Mobile Experience Awards
Market Overview
In Opensignal's latest Indonesia Mobile Network Experience report, Telkomsel dominates the awards table, winning 10 awards outright and one jointly — as it increases its award count from 7 sole and one shared wins in the previous report. IM3 secures three outright wins for Games Experience, Time on Network, and Reliability Experience. Meanwhile, XLSmart is the sole winner of both Voice App Experience awards — overall and 5G — and shares the winners’ podium with Telkomsel for 5G Games Experience.
XLSmart has been rapidly improving its coverage post-merger through National Roaming and MOCN initiatives. It has expanded its 4G coverage in Eastern Indonesia, Kalimantan, and across Bali.
In this report, Opensignal introduces a revised 5G Availability metric, which defines 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. Previously, the metric measured 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. Additionally, our Availability metric has been renamed to Time on Network to align with methodological updates in other metrics.
We have examined the mobile network experience of the three main mobile network operators in Indonesia — Indosat, Telkomsel, and XL — over a 90-day period starting on August 1, 2025, and ending on October 29, 2025, to understand how they performed. Alongside our national analysis, we also explored users' mobile network experience across 10 of Indonesia's major regions.
Overall Experience
National Analysis
Telkomsel seizes the Video Experience award from IM3 and wins it outright with a score of 66.0 points on a 100-point scale, beating IM3 by one point.
IM3, Telkomsel, and XL all rate as Good (58-68) for overall mobile video streaming services. This means that our users are, on average, able to stream video at 720p or better with satisfactory loading times and minimal 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.
Games ExperienceDefinitions
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
IM3 retains the Games Experience award with a score of 83.7 points on a 100-point scale. It holds a winning margin of less than one point over second-placed XL and Telkomsel, whose scores are statistically tied at 83.2-83.3 points.
Regardless of their choice of mobile operator, our Indonesian users enjoy a Good (75-85) experience in mobile gaming. Most users deem the experience acceptable. Gameplay is generally controllable, and users receive immediate feedback between their actions and in-game outcomes, with little to no noticeable delay.
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
Telkomsel triumphs in Upload Speed Experience with a score of 12.4Mbps — 0.5Mbps ahead of second-placed XL. All Indonesian operators have seen increases in their Upload Speed Experience scores, ranging from one to two Mbps.
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.

Coverage
National Analysis
Telkomsel wins the Coverage Experience award outright with a score of 8.7 points on a 10-point scale. It commands a sizable lead over its competitors, as IM3 scores 5.3 points and XL scores 4.7 points.
These scores indicate that Telkomsel has the widest geographic coverage footprint in populated areas among all mobile operators in Indonesia.
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
Telkomsel wins the 5G Coverage Experience award outright with a score of 0.23 points — more than twice the score of second-placed IM3 at 0.11 points.

National Analysis
IM3 remains the sole winner of Time on Network with a score of 97.8%. This figure represents the proportion of time Opensignal users spend connected to a 5G, 4G, or 3G mobile signal.
Definitions
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.
National Analysis
Telkomsel wins the 5G Availability award outright with a score of 19%, beating IM3 by nearly ten percentage points. This score reflects 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.

Consistency
National Analysis
Following a six-percentage-point increase in its score, Telkomsel pulls ahead of the previous outright winner IM3 and seizes the Consistent Quality award with a score of 72.4%, holding a lead of one percentage point over IM3.
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
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.
National Analysis
Our users in Indonesia continue to enjoy the most reliable mobile services on the IM3 network, as the operator wins the Reliability Experience award with a score of 877 points on a 100-1000 point scale — six points ahead of XL. Both Telkomsel and XL are close on IM3’s heels and have significantly reduced IM3’s winning margin. Telkomsel's score has increased by 31 points since the previous report, while XL's has risen by 14 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:
a) Signal Availability — the proportion of time Opensignal users can successfully receive a mobile network signal,
b) Data Connectivity — the proportion of time when the network is available and the device can connect to the internet,
c) Task Completion — whether tasks initiated by the user’s device are completed,
d) Sufficiency — the probability that basic tasks will be executed sufficiently well for the user.
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.
Why confidence intervals are vital in analyzing mobile network experience
