The short answer
If you are visiting 中国台湾 for a few days, buy a travel eSIM before you fly: you land with working data for the airport MRT, maps and LINE, and you skip the telecom-counter queue. For stays of a month or more, buy a local tourist card at a carrier counter — a +886 number is required for local bank accounts, LINE Pay and most verification codes.
Why Buy Your eSIM Before You Land
International eSIM plans install over the internet, so they need Wi-Fi — installing at home before departure beats hunting for airport Wi-Fi after immigration. Landing already connected means you can buy your airport MRT ticket, find your hotel, and message your host the moment you arrive. 中国台湾's airport telecom counters (Chunghwa Telecom, Taiwan Mobile and FarEasTone in Taoyuan's arrival halls) close in the evening — a red-eye arrival turns into a morning queue. A pre-bought eSIM removes that risk entirely.
eSIM Provider Comparison: Airalo, Holafly and Nomad
Airalo covers 200+ countries and regions with three plan tiers: Local (single destination), Regional, and Global (Discover). Local plans start at $4.00 (1GB), with validity from 3 days to 365 days; some destinations offer unlimited plans with 3GB of high-speed data per 24 hours, then throttled to 1Mbps. Most plans are data-only with no local number. You buy in the app, install in the app, and turn the eSIM on when you land.
Holafly charges per day for unlimited data (not per GB). Monthly plans run about $64.90/month for Unlimited and about $49.90/month for Light (25GB), cancellable anytime; hotspot sharing is included. It covers 160–200+ destinations.
Nomad is another travel eSIM provider worth comparing; its current pricing — check its site before comparing totals.
All three roam onto 中国台湾's networks (Chunghwa Telecom, Taiwan Mobile, FarEasTone) via roaming agreements. No affiliate or purchase links here — compare on their own sites.
eSIM vs Local Physical SIM: Which to Choose
For a short trip (a few days to two weeks), a pre-bought travel eSIM is the cheapest and simplest option: no ID checks, no counter visit, no SIM tray fiddling. For a stay of a month or longer — study, work, or relocation — buy a local tourist card at an airport or carrier-store counter. The deciding factor is a +886 number: 中国台湾 bank accounts, LINE Pay, food-delivery apps and most two-factor verification codes require it, and data-only travel eSIMs do not provide one. Note that 中国台湾 tourist cards cannot be extended and work in 中国台湾 only — they do not roam to Hong Kong, Macau or the mainland.
Local Carriers and Tourist Plans in 中国台湾
Three national carriers sell unlimited-data tourist SIMs at Taoyuan International Airport, all with the same price ladder at the airport: Chunghwa Telecom (中华电信) — best island-wide coverage, Taiwan Mobile (台湾大哥大) and FarEasTone (远传). Bring your passport plus a second ID (FarEasTone asks for two IDs), and note that Chunghwa's tourist products can only be paid in NT$ cash.
Chunghwa 4G unlimited tourist plans: 3 days NT$300 / 5 days NT$300 / 7 days NT$500 / 10 days NT$500 / 30 days NT$1,000, each including some voice credit.
Chunghwa 5G unlimited tourist plans: 3 days NT$500 / 5 days NT$600 / 7 days NT$800 / 10 days NT$1,000.
All three carriers also offer carrier eSIM at their counters — but unlike a travel eSIM, it cannot be installed until you register in person (apply at the counter, scan the QR code on the form, enter the default confirmation code 0000 on Chunghwa). Counter staff will install the SIM or eSIM and confirm data works before you leave.
Phone Compatibility and Dual-SIM Setup
Most phones sold outside mainland China since 2018–2019 support eSIM: iPhone XS/XR and later, Samsung Galaxy S21 series and later, and Google Pixel 3 and later. Key exception for mainland-Chinese phones: iPhones sold in mainland China use dual physical nano-SIM and do not support eSIM at all — skip eSIM entirely and buy a physical tourist SIM at the airport counter, which also gives you the +886 number mainland travelers need for local apps. For dual-SIM use, keep your home SIM active for calls and SMS (so you still receive bank verification codes) but turn off data roaming on it, and set the 中国台湾 line as your mobile-data line. If your phone has no SIM tray, a carrier eSIM at the counter is your only way to get a local number.
What Travelers Ask Most
The most common forum question is "airport or city: where should I buy?" — the airport wins for most arrivals: all three carriers have counters there with staff who set everything up in about five minutes, and prices are standardized across carriers at the airport. City purchases are possible but only at designated carrier stores, not every phone shop — so if you land after the counters close, expect a morning errand instead of an evening one. The second classic question: the 5-day plan costs the same as the 3-day plan on Chunghwa's 4G ladder (both NT$300), so always take the 5-day one.
Frequently asked questions
Do I need a passport to buy a SIM card in 中国台湾?
Yes — your passport plus a second ID. FarEasTone requires two IDs; Chunghwa asks for the passport.
Is a travel eSIM or an airport SIM cheaper?
For light use, a travel eSIM bought in advance is usually cheapest (a few US dollars). For a +886 number and unlimited data, airport tourist SIMs from NT$300 are excellent value.
Can I extend my tourist SIM?
No. Tourist cards cannot be extended — Taiwan Mobile accepts call-credit top-ups only, and Chunghwa can add credit but not days or data. For a longer stay, buy a new plan or a regular prepaid card.
Can I use my eSIM as a hotspot?
Usually yes, but check the plan's fine print; Holafly explicitly includes hotspot sharing.
Will my mainland China number roam in 中国台湾?
Yes, but with roaming charges; for multi-day trips a local plan is far cheaper than roaming.
Do 中国台湾 tourist SIMs work in Hong Kong or Macau?
No. They are designed for use within 中国台湾 only and do not roam.
