Advanced Info Service Public Company Limited (AIS) is Thailand’s largest mobile network operator, offering comprehensive wireless communication services across the country. The company provides voice, messaging and data connectivity over its 2G, 3G, 4G and 5G networks, serving both prepaid and postpaid subscribers. AIS continuously expands its network infrastructure to deliver high-speed mobile broadband and enhanced coverage in urban and rural areas alike. As a key player in Thailand’s telecommunications industry, the firm focuses on network quality and customer experience to sustain its market leadership.
In addition to traditional mobile services, AIS has diversified into fixed broadband solutions, delivering high-capacity fiber‐to‐the‐home (FTTH) and wireless broadband access for residential and corporate customers. The company’s enterprise arm offers managed ICT solutions, cloud computing, Internet of Things (IoT) services and data center facilities, enabling businesses to digitalize operations and improve efficiency. AIS also operates digital platforms that include mobile payment, digital content streaming, e‐wallet services and e‐commerce partnerships, reflecting its strategy to evolve from a pure‐play network operator into a digital services provider.
While the core of AIS’s operations is rooted in Thailand, the company leverages strategic partnerships and investments to extend its digital footprint in Southeast Asia. It collaborates with regional telecom operators and technology firms to pilot new services and explore market opportunities in neighboring countries. Through alliances and joint ventures, AIS seeks to capitalize on cross‐border synergies in content distribution, mobile roaming and enterprise solutions.
Founded in the late 1980s under a concession granted by the Thai government, AIS launched its first commercial services in the early 1990s and has since grown under the umbrella of Intouch Holdings, a subsidiary of the Charoen Pokphand Group. The company’s leadership team is headed by Chairman Suphachai Chearavanont, with Somchai Lertsutiwong serving as Chief Executive Officer. Under their guidance, AIS continues to invest in network innovation, digital transformation and strategic partnerships to maintain its position at the forefront of Thailand’s telecom industry.
