Taiwan’s fixed communication services market will see modest growth in its revenue from $3.3 billion in 2025 to $3.4 billion by 2030 with a compound annual growth rate (CAGR) of just about 0.6%, as a steady decline in fixed voice services weighs down growth in fixed broadband services segment, according to GlobalData, a leading intelligence and productivity platform.

GlobalData’s Taiwan Fixed Services Forecast (Q1-2026) reveals that the total fixed voice service revenue in the country will decline significantly over the forecast period, due to steady losses in circuit-switched subscriptions, as users shift from traditional voice services to mobile- and Internet-based communication services.

Fixed broadband service revenue, on the other hand, is expected to increase at a 4.6% CAGR during 2025-30, led by strong growth in fiber-to-the-home (FTTH) lines. Operators are upgrading the high-speed fiber infrastructure, driven by demand for smart home services, and bandwidth-intensive applications such as video streaming, remote work, online learning, and cloud services.

Sarwat Zeeshan, Telecom Analyst at GlobalData, comments: “Fiber will remain the leading broadband technology in terms of subscription share through the forecast period, supported by rising demand for high-speed broadband connectivity, as well as the efforts by the government and telecom operators to expand and upgrade fiber broadband network in the country.”

Chunghwa Telecom is expected to lead the fixed broadband services market in 2026, in terms of subscriber base, and will maintain its leadership through 2030, thanks to its strong position in the fiber-to-the-home/building (FTTH/FTTB) segment. It continues to expand its broadband business through speed upgrades and accelerate fiber deployment to broaden coverage. The operator is promoting higher-speed gigabit plans (1Gbps and above) for households and SMEs, which is expected to drive its revenue growth.

Zeeshan concludes: “Taiwan’s fixed communications market will increasingly depend on operators’ ability to monetize next-generation fiber networks through premium broadband tiers and value-added digital services. Investments in multi-gigabit connectivity, enterprise cloud solutions, and smart home ecosystems will be critical to sustaining revenue growth, offsetting legacy voice declines, and strengthening long-term customer value.”
