Thailand Telecommunications Sector Report 2025-2026

Thailand's telecommunications market is characterised by a high degree of maturity and a strong mobile-first orientation, underpinned by aggressive network deployments and supportive government policies. While the overall information and communication technology (ICT) sector experienced a slight deceleration in growth in early 2025, robust investment inflows, particularly in data centres and cloud services, are driving significant productivity gains and positioning Thailand as a burgeoning digital hub. The mobile segment, dominated by a duopoly of Advanced Info Service (AIS) and True Corporation, exhibits near-saturation with a penetration rate of almost 175%, reflecting widespread multi-SIM ownership. This mature market prompts operators to prioritise customer retention and average revenue per user (ARPU) growth through enhanced data usage and value-added services, rather than solely focusing on new subscriber acquisition.
