Network coverage in Taiwan

Local carriers

Taiwan has three major carriers: Chunghwa Telecom (CHT), Taiwan Mobile, and FarEasTone (FET). All three run 5G in Taipei, New Taipei, Taichung, and Kaohsiung, and 4G LTE across the island. Chunghwa Telecom is the incumbent and has the deepest rural penetration, including mountain areas and small east coast fishing villages. Taiwan Mobile is strong in western urban corridors. FarEasTone performs competitively in northern Taiwan. International eSIM plans for Taiwan are available but the country's eSIM market for visitors was slower to develop than South Korea or Japan. Plans connect through Chunghwa or Taiwan Mobile depending on provider. Taiwan's NCC has required all carriers to maintain indoor coverage at train stations and MRT systems.

Coverage analysis

Taipei delivers outstanding coverage. All five MRT lines and the Taipei 101 observation deck maintain signal. Taipei Main Station and Songshan Airport are fully covered. Taoyuan International Airport (TPE) has 5G in all terminals. The High Speed Rail connecting Taipei to Kaohsiung maintains 4G throughout the route at 300 km/h. Taroko Gorge National Park is a notable win for Taiwan's network: most of the gorge road between Hualien and Tiansiang has 4G from Chunghwa despite the steep canyon walls. Sun Moon Lake has solid coverage at the lakefront. Alishan mountain has coverage in the visitor village. The east coast Highway 11 from Hualien to Taitung maintains 4G throughout. High mountain trails above 3,000 meters, including Jade Mountain (Yushan) approaches, have thinner coverage on remote sections. Download offline maps for any backcountry hiking.
