Carrier counters in arrivals
Chunghwa Telecom, Taiwan Mobile and FarEasTone run counters in the arrival halls of both terminals, selling prepaid tourist SIMs with unlimited or capped data for set numbers of days. Queues build when several long-haul flights land together.
- Bring your passport. SIMs are registered to your name; counters may also ask for a second photo ID such as a driving licence.
- Check counter hours. Reported hours vary by carrier and terminal; very late arrivals may find some counters closed.
- Unlock your phone before you travel if it is tied to a carrier at home.
eSIM
If your phone supports eSIM, a Taiwan data eSIM bought online before departure starts working when you land, with no counter visit. Data-only eSIMs do not give you a local phone number, which some apps and taxi or delivery services ask for.
Free Wi-Fi as a backup
Terminals and Airport MRT trains have free Wi-Fi, so you can get to the city and sort a SIM later. See services.
