Global mobile network speed authority OpenSignal released Taiwan’s July 2026 mobile network experience report on July 31, 2026. Compared with the previous period, the ranking order of the three major telecoms in network quality was similar, but Taiwan Mobile was the big dark horse of improvement, adding one award each in Winner and Joint Winner.
In the first half of 2026, who had the best mobile network quality, and who improved the most? How can you wisely choose a telecom carrier? Here is a summary and analysis:
1. Taiwan July 2026 Mobile Network Experience Report (OpenSignal)
A. First Half of 2026 Mobile Network Experience Report Reward:
According to the latest announcement from OpenSignalTaiwan Mobile Network Experience ReportChunghwa Telecom won the most awards, followed by Taiwan Mobile, with Far EasTone in third. This result is related to Taiwan Mobile and Far EasTone having to integrate Taiwan Star and Asia Pacific Telecom, which had poorer network quality in the past. Compared with the previous period, Chunghwa Telecom lost one Winner, while Taiwan Mobile gained one Winner and one Joint Winner, showing the most improvement; Far EasTone lost one Joint Winner award. So Taiwan Mobile improved the most.
Among them, “Experience Quality” — placed at the top of OpenSignal’s awards this edition (including “Reliability Experience” and “Quality Consistency”) — is arguably the hardest metric to secure in the telecom industry. This time, Taiwan Mobile replaced Chunghwa Telecom to take the crown.
This indicator represents that the mobile network is not just about fast single-point speed tests, but about avoiding abnormal interruptions and speed drops across “all time periods and all scenarios,” making it extremely challenging overall. This means Taiwan Mobile has effectively leveraged the 700+900MHz dual low-frequency bands and the 3.5GHz 100MHz large bandwidth, combined with NRCA smart integration technology after merging with Taiwan Star, to deliver users the most reliable and consistent mobile network quality—a truly commendable achievement.
B. H1 2026 Mobile Network Most Improved Brand:
According to OpenSignal’s latest Taiwan Mobile Network Experience Report, Taiwan Mobile has become the biggest dark horse in network quality improvement, showing that it has gradually overcome the transition period of merging with Taiwan Star, and has even surpassed Chunghwa in some categories.
In terms of 5G network quality, Taiwan Mobile won 4 Best Improvement awards, including 5G upload speed, 5G coverage experience, 5G gaming experience, and 5G voice application experience.
In terms of overall (4G+5G) network quality, Taiwan Mobile emerged as a dark horse, sweeping four individual category championships in overall video experience, quality consistency, overall reliability, and overall availability rate. It also won three improvement awards (overall download experience, overall upload experience, and overall voice app experience), tying with Far EasTone for first place.
Among all 14 awards, Taiwan Mobile took 7, surpassing Far EasTone and Chunghwa Telecom’s 3 (declining 5G download speeds were not counted). Following its Opensignal award for “4G/5G Availability – Global No.3” in this year’s February report, Taiwan Mobile has become the winner of the Most Improved Mobile Network Quality Award for the first half of 2026—truly well deserved.
3. How to choose a telecom carrier wisely?
OpenSignal’s Taiwan Mobile Network Experience Report divides 16 awards into four categories: Experience Quality, Network Performance, Coverage Experience, and App Experience. Each of the three carriers has its own strengths and weaknesses. These four categories of network quality indicators actually conflict with one another, making it difficult to have it all. Therefore, consumers should choose a carrier plan that suits their mobile network usage preferences.
Take the forum moderator as an example. The moderator is a heavy internet user with monthly data usage exceeding 100GB. In addition to being a blogger who must constantly stay online to keep an eye on things, binge-watching shows and AI animations are the most data-consuming parts of daily life. They place greater importance on the reliability and consistency of the mobile network than on speed requirements.
Taiwan Mobile has been recognized by OpenSignal as number one in Taiwan for quality consistency, reliability experience, overall and 5G video experience, network availability, and 5G voice experience. For someone like the thread starter who is a heavy internet user, prefers streaming videos, and values network stability, it’s naturally a smart choice to make Taiwan Mobile the primary phone service!
