The Taiwan plans in our database use Taiwan Mobile, Chunghwa Telecom. Where a provider hasn't published it, the table shows "Network not published". Chunghwa Telecom and Taiwan Mobile cover the whole island, including the Taroko and Alishan routes.
For maps, messaging and light browsing, about 0.3–0.5GB a day, so 3–5GB is enough for 7 days. If you often watch videos or share a hotspot, consider unlimited data. To save money, choose Yesim 30GB · 30 days, the best value per GB (US$0.80 / GB).
Most providers don't list hotspot limits in their details, so please read the plan details before you buy. A travel eSIM is data only and works alongside your own SIM, so WhatsApp keeps working. Calls and SMS to your usual number still go through your own carrier (roaming charges may apply).
Chunghwa Telecom sells prepaid SIM cards and eSIMs for visitors at service counters in Taiwan's main airports. You need your passport and a second ID, and you pay in New Taiwan dollars, cash only. A travel eSIM can be bought and installed online before you leave, so you just turn on data when you land and skip the counter. Plans and lengths differ, so compare them for your trip.
