## About T Star

Taiwan Star Telecom (台灣之星), operating as T Star, is a mobile network operator in Taiwan, located within the Asia & Middle East region. Designated with Mobile Country Code (MCC) 466, which identifies Taiwan, and Mobile Network Code (MNC) 89, T Star provides mobile services to subscribers across the country. While not one of the "big three" (Chunghwa Telecom, Taiwan Mobile, and Far EasTone), T Star aimed to differentiate itself through competitive pricing and targeted data plans, focusing on attracting a value-conscious customer base in Taiwan's highly competitive mobile market.

T Star's network infrastructure has included both 4G LTE and, more recently, 5G technologies, allowing users access to faster mobile data speeds. Their strategy involved partnerships and infrastructure sharing to expand coverage and improve service quality. Although the Taiwanese mobile market is quite saturated, T Star has actively sought to carve out its niche, often offering promotions and value-added services designed to appeal to younger demographics and heavy data users. The MCC 466 identifies all mobile network operators in Taiwan, with each operator possessing a unique MNC (like 89 for T Star) that distinguishes them within the Taiwanese mobile landscape.
