Taiwan’s mobile service market is set for steady growth, with total revenue projected to rise from $5.9 billion in 2025 to $6.2 billion by 2030, representing a compound annual growth rate (CAGR) of 1.0 percent, according to the latest Taiwan Mobile Broadband Forecast (Q2 2025) by GlobalData. The expansion will be fueled primarily by the surge in 5G subscriptions and the rising adoption of mobile data services.
Mobile Voice Revenue Decline
While overall revenue edges upward, mobile voice service revenue in Taiwan will decline at a sharp 10 percent CAGR between 2025 and 2030. This drop is attributed to decreasing average revenue per user (ARPU) as subscribers increasingly favor OTT and internet-based communication platforms over traditional voice calls.
Data Services to Drive Growth
Conversely, mobile data service revenue in Taiwan is expected to climb at a 3.2 percent CAGR over the same period. Higher-ARPU 5G plans and greater reliance on mobile data for entertainment and social media will underpin this rise.
GlobalData Telecom Analyst Kantipudi Pradeepthi highlights that average monthly mobile data usage will grow from 36.4 GB in 2025 to about 44 GB in 2030, spurred by high-bandwidth activities such as video streaming, gaming, and social networking.
5G to Dominate Taiwan’s Mobile Market
5G technology is poised to dominate more than 95 percent of total mobile subscriptions by 2030. This rapid adoption stems from the availability of 5G-enabled smartphones and the continued expansion of 5G networks across Taiwan.
Chunghwa Maintains Market Leadership
Major telecom operators, including Chunghwa Telecom and Taiwan Mobile, have already accelerated their 5G rollout through strategic partnerships with Nokia in late 2024 to enhance coverage and speed.
Chunghwa Telecom remains the top player in Taiwan’s mobile services market in 2025, ahead of Taiwan Mobile and FarEasTone.
GlobalData predicts Chunghwa will retain its leadership through 2030, thanks to aggressive 5G network expansion and competitive, flexible pricing plans. The operator’s emphasis on value-added services such as music, movie streaming, TV, and cloud gaming further strengthens its market position.
As of June 30, 2025, Chunghwa Telecom reported 13.13 million mobile subscribers, down 2.2 percent year over year. Despite the decline in subscribers, second-quarter mobile service revenue rose 2.0 percent to NT$17.06 billion, while post-paid ARPU (excluding IoT SIMs) remained steady at NT$556.
Chunghwa Telecom’s mobile subscriber market share is about 38-39 percent, while its share of mobile service revenue is slightly higher, around 40-40.5 percent. Of its subscriber base, over 3 million are 5G users; its 5G subscriber market share is also roughly 38.7-38.8 percent.
Chunghwa Telecom is investing heavily in both infrastructure and new service capabilities. It plans to invest NT$32.36 billion (Taiwan dollars) in 2025 toward expansion of its 5G network, AI/data centres (IDC), and submarine cable infrastructure. The company also continues to promote “migration” from 4G to 5G, which is generating ARPU uplift, especially for its postpaid customers.
FarEasTone has also been active. Its postpaid base is strong (several million users) and its 5G penetration among postpaid customers is growing. In early-2025, FarEasTone set a target of reaching 50 percent 5G penetration among its customer base. It has also been phasing out unlimited 4G plans and pushing customers toward 5G subscriptions, which reflects its strategy to encourage migration to higher band, higher-value services.
In terms of innovations, FarEasTone in partnership with Ericsson has done trials using 5G Advanced technologies and differentiated connectivity / network slicing in dense event settings (e.g. at Taipei Dome for large concert events), using features like Automated Radio Resource Partitioning and Network APIs to offer better user experience under load.
Taiwan Mobile’s mobile subscriber base surpassed 10 million following its merger with Taiwan Star, with postpaid ARPU continuing to rise and churn falling to around 0.58 percent in early 2025. For 2025 the company approved capital expenditure of about NT$8.58 billion focused on mobile and fixed networks, cable broadband, and digital TV, along with about NT$0.69 billion for e-commerce development.
Taiwan Mobile is also investing NT$11 billion in a green energy platform with Fubon Group to develop roughly 380 MW of solar power and 354 MW of energy storage as part of its goal of 100 percent renewable energy by 2040 and net-zero emissions by 2050.
Pursuing its “Telco + Tech” strategy, the operator is expanding enterprise services such as cloud, AI, and cybersecurity, introducing new digital products and bundled video services, and has taken an 11.86 percent stake in Systex Corporation to strengthen capabilities in AI, 5G private networks, and overseas expansion.
