Thailand’s fixed communication services revenue is expected to witness a steady growth through 2030, driven by growth in the fixed broadband service segment, reveals GlobalData, a leading intelligence and productivity platform.

GlobalData’s Thailand Fixed Services Forecast (Q4-2025) reveals that fixed communication services revenue in Thailand is expected to maintain a compound annual growth rate (CAGR) of about 2.6%, driven by the continued growth in fixed broadband services.

Fixed voice service revenue will decline significantly over the forecast period due to losses in circuit-switched subscriptions and decline in fixed voice service ARPU over the forecast period, as users shift from traditional voice services to OTT/app-based communications.

Fixed broadband service revenue, on the contrary, is expected to increase at 3% CAGR, supported by strong growth in fiber-to-the-home (FTTH) and fixed wireless access (FWA) lines, in line with the anticipated growth in broadband household penetration levels in the country as the government and telcos plans to provide high-speed home internet connectivity to bridge the urban-rural digital divide. This growth will also be driven by the increasing adoption of fixed broadband services as telcos offer bundled content offerings and integrated digital services.

Neha Mishra, Telecom Analyst at GlobalData, comments: “Fiber will remain the leading broadband technology, increasing its share of total fixed broadband subscriptions  from 96.9% in 2025 to 97.7% in 2030. This growth is supported by a rising demand for higher-speed broadband connectivity and telcos’ focus on expanding FTTH service coverage across the country.”

AIS led the fixed broadband services market in 2025 and is expected to maintain its leadership through 2030. Its leadership is reinforced by its strong position in the fiber segment and focus on fiber network expansion. For instance, as of March 2026, AIS expanded its broadband network to over 20 million households across Thailand.

Mishra concludes: “Thailand’s fixed communications market will continue to evolve around fiber-led broadband expansion and service convergence. As the demand for high-speed connectivity grows, operators will focus on network upgrades, fiber expansion, and bundled offerings to enhance value and retain customers.”
