Total Access Communication Public Company Limited, commonly known by its brand name “dtac,” is a leading telecommunications provider in Thailand. The company offers a wide range of mobile services including prepaid and postpaid voice plans, mobile data packages, and value-added digital solutions. In addition to traditional voice and data offerings, dtac provides enterprise services such as Internet of Things (IoT) connectivity, machine-to-machine communications, and wholesale bandwidth to other carriers and service providers.
Founded in 1989, dtac has grown to become one of the top three mobile operators in Thailand. The company launched its first commercial mobile network in the early 1990s and subsequently expanded coverage to encompass both urban centers and rural areas across the country. In 2005, Total Access Communication went public on the Stock Exchange of Thailand, marking a significant milestone in its corporate development. Over the years, dtac has continually upgraded its network infrastructure, rolling out 3G, 4G LTE and, more recently, 5G services to meet rising consumer demand for high-speed connectivity.
Today, dtac serves millions of subscribers nationwide, maintaining a focus on customer experience through initiatives in digital self-service, customer care and loyalty programs. The company is majority-owned by the Telenor Group, a global telecommunications operator headquartered in Norway, which supports dtac’s strategic planning and technology investments. With ongoing expansions in network capacity and digital offerings, dtac aims to strengthen its position in Thailand’s competitive telecom market.
