Summary
For a 1-week trip across Taipei, Kaohsiung, or Taichung, a 5–10 GB travel eSIM on Chunghwa Telecom or Taiwan Mobile costs about US$6–12 with reliable 5G. Chunghwa leads 5G coverage and is the strongest all-round network for travelers — far cheaper than home-carrier roaming for the same week.
Taiwan's mobile networks in 2026
Taiwan has three major carriers — Chunghwa Telecom, Taiwan Mobile, and Far EasTone. Chunghwa leads the 5G coverage experience, with Taiwan Mobile a solid choice for urban and tourist-zone service. Coverage is excellent across Taipei, Kaohsiung, Taichung, Tainan, and along the high-speed rail corridor, so a Chunghwa- or Taiwan Mobile-backed eSIM serves nearly any itinerary; remote east-coast and mountain routes can drop to 4G.
