Where to buy a SIM card in Taiwan
The best place to buy is Taoyuan International Airport (TPE) arrivals hall, counters from all carriers. Here is what each channel offers and what to expect.
Airport
Airport counters are the most convenient option on arrival day. Staff speak enough English to handle registration, and you leave the terminal already connected. Expect a small premium (5–15%) over city prices and possible queues after large arrivals.
Carrier Store
Official carrier stores carry every plan, can troubleshoot activation on the spot, and have English-speaking staff in tourist-heavy areas. Prices match the carrier website.
Convenience Store
Convenience stores stock prepaid SIM cards near the checkout. Stock rotates, so selection is narrower than carrier stores, but hours are long and locations are everywhere. Bring your passport.
Buying experience
Taoyuan Airport Terminal 1 and Terminal 2 both have Chunghwa Telecom and Taiwan Mobile counters in the arrivals areas. The Chunghwa counter at Terminal 2 arrivals is on the right as you walk toward the exit. Staff speak serviceable English and the product selection is straightforward. You point to a plan duration on the board, show your passport, and the SIM is inserted and tested in your phone before you leave. Most travelers are done in 8 minutes. If traveling to Jiufen, Sun Moon Lake, or Kenting, the airport SIM is the best moment to get connected. Coverage is good at all these tourist destinations.

Chunghwa Telecom leads on overall coverage with a rating of 5/5 for reach and 5/5 for speed. In cities, all providers perform similarly. Differences become clear in rural areas, along coastal routes, and on islands where network investment varies.
Real-world connectivity
Taipei delivers fast and consistent 4G LTE across the city. The MRT system has full signal in all stations and on trains. Taiwan's east coast is more varied: Hualien and Taroko Gorge entrance have good Chunghwa signal. The road through the gorge itself has signal in most sections but drops in the deepest canyon sections. Alishan mountain railway route has coverage in Chiayi and at the summit area but gaps in between. The Pingtung and Kenting coastline has solid 4G. Orchid Island has limited coverage from Chunghwa only. Download your offline maps before any east coast mountain travel.
Our verdict on SIM cards in Taiwan
Best for: Taipei city visitors, East coast and Taroko Gorge travelers, Transit travelers with short layovers.
Local tourist SIMs cost TWD 300-1000 ($10-33) for 5-30 days with unlimited data, which is excellent value. eSIM costs about the same for capped data. For short trips, the unlimited local SIM is arguably better value. For travelers who want to set up before landing, eSIM is more convenient.
