Taiwan is one of the easiest places in Asia to get online, and one of the cheapest for unlimited data. That changes the usual eSIM-versus-SIM math. In most countries an eSIM wins on price and convenience. In Taiwan the local tourist SIMs are so cheap and genuinely unlimited that the honest answer for a remote worker is: use both, for different jobs.
The short version. For a stay of a week or more, buy a Chunghwa Telecom prepaid tourist SIM. It has the best coverage on the island by a clear margin, the fastest 5G, and the strongest signal once you leave Taipei for the mountains, the east coast, or the outlying islands, exactly where the other networks thin out. If you only stay in Taipei, Kaohsiung and the western cities, Taiwan Mobile or FarEasTone are cheaper for unlimited data and you will not notice the difference. And to land already connected, without hunting for an airport counter jet-lagged, install a [Saily](https://saily.com) eSIM before you fly. It carries you from the plane door to the moment you pick up a local SIM, and for a short trip of a few days it can be the only thing you need.
Taiwan's three carriers, honestly compared
Taiwan has three networks that matter, and the gap between them is real but narrow in the cities.
Chunghwa Telecom (中華電信) is the former state carrier and the market leader with roughly 13 million subscribers. It runs 4G across all 368 townships and holds the largest 5G spectrum share in the country. Independent Opensignal testing consistently puts it top for coverage, and its median 5G download speed sits around 340 Mbps. If your work depends on a reliable signal in unpredictable places, this is the default. It is not the cheapest, but the coverage premium is worth it the moment you take a Taroko Gorge day trip or work from Hualien.
Taiwan Mobile (台灣大哥大) is the strong number two. Its 5G is excellent in the cities and it covers the offshore islands of Kinmen and Matsu well. Its unlimited tourist plans tend to undercut Chunghwa. This is a smart pick for a city-based nomad who wants unlimited data cheaply.
FarEasTone (遠傳電信) rounds out the trio with near-total population coverage and an aggressive push on 5G base stations. Its 30-day unlimited plan is one of the best long-stay values on the island, and it runs a dedicated service centre at Taoyuan Airport that is often less crowded than the Chunghwa desk.
Two smaller players, Taiwan Star and GT (formerly Asia Pacific Telecom), were absorbed into Taiwan Mobile and FarEasTone in the operator consolidation, so you will rarely see them offered to tourists now.
Prices and plans (2026)
Taiwan sells tourist SIMs as flat-rate day passes, almost all with truly unlimited data and hotspot tethering included. There is no per-GB anxiety here. Prices below are indicative 2026 airport and store rates; expect small variation and occasional online-booking discounts.
| Option | Data | Price (approx.) | Coverage | Where to buy |
|---|---|---|---|---|
| Chunghwa 5-day pass | Unlimited | NT$600 (~$19) | Best on island, incl. rural/mountains | Airport, 1,000+ stores, convenience stores |
| Chunghwa 30-day 4G pass | Unlimited | NT$1,000 (~$32) | Best on island | Airport, carrier stores |
| Chunghwa 5G 60-day | 60GB | ~NT$1,100 (~$35) | Best 5G | Carrier stores, airport |
| Taiwan Mobile 5-day | Unlimited | NT$500 (~$16) | Excellent in cities | Airport, carrier stores |
| FarEasTone 30-day | Unlimited + voice credit | NT$1,000 (~$32) | Near-nationwide | Taoyuan service centre, stores |
| Saily eSIM (5GB) | 5GB / 30 days | ~$11.99 | Local network | App, before you land |
| Saily eSIM (20GB) | 20GB / 30 days | ~$30.99 | Local network | App, before you land |
| Airalo eSIM (5GB) | 5GB / 30 days | ~$12 | Taiwan Mobile | App, before you land |
The standout here is the local unlimited pricing. Roughly $32 for a full month of unlimited data on the best network in the country is excellent value by any Asian standard, and it is why a heavy-usage remote worker staying two weeks or more is usually better off on a local SIM than on a capped eSIM.
Landing connected: why an eSIM earns its place
The airport SIM counters at Taoyuan (TPE) sit post-security in both terminals, with Chunghwa, Taiwan Mobile and FarEasTone all represented, and there are desks at Taipei Songshan (TSA) and Kaohsiung (KHH) too. The catch: these counters typically close from around midnight until 6am. If your flight lands late, or if there is a queue of a full A330 ahead of you, you are offline exactly when you want to book a taxi, message your accommodation, or confirm a morning call.
This is the job an eSIM does best. Install a [Saily](https://saily.com) plan the night before you fly, and it activates the moment you connect to a Taiwan network on landing. No counter, no queue, no passport form while you are half-asleep. Saily's Taiwan plans start at $3.99 for 1GB (7 days) and run up through 5GB at about $11.99 and 20GB at about $30.99 for 30 days. One honest caveat: Saily's "unlimited" Taiwan plan is really a fair-use 5GB per day at full speed, then throttled to around 1 Mbps, so for genuinely heavy daily use the local unlimited SIM is the better tool. For arrival and short trips, though, a modest Saily data plan is exactly right.
Airalo is a reasonable alternative and runs on Taiwan Mobile's network, with 5GB around $12 and 20GB around $29, but it is data-only with no phone number. Either way, the eSIM's role for a longer stay is the bridge, not the whole trip.
One requirement: your phone must support eSIM (any recent iPhone, Pixel, or flagship Samsung does) and be carrier-unlocked. Taiwan itself supports eSIM well, and Chunghwa even offers its own local eSIM, but the tourist eSIM ecosystem is built around the international providers above.
The best local SIM for a longer stay
If you are settling in for a few weeks of remote work, here is the decision tree.
- Leaving Taipei often, or working from Hualien, Taitung, Kenting, Alishan, or the outer islands? Buy Chunghwa Telecom. Its rural and mountain coverage has no real rival, and dropped signal on a client call is not worth saving a few dollars.
- Staying mostly in Taipei, Taichung, Tainan or Kaohsiung? Taiwan Mobile or FarEasTone give you unlimited data for a little less, and the city coverage is effectively identical to Chunghwa.
- Want the longest single validity window? FarEasTone's 30-day unlimited plan and Chunghwa's 30-day pass both cover a full month without a top-up.
Buying is simple. Bring your passport, required for registration on every carrier. Beyond the airport, Chunghwa alone runs over 1,000 retail stores nationwide, and you can also pick up or reload SIMs at 7-Eleven and FamilyMart convenience stores, which are on nearly every corner. Staff at flagship city stores usually speak enough English to sort you out; convenience-store clerks may not, so the airport or a main carrier shop is the smoother first stop.
If you are staying longer than the tourist-pass windows allow (they typically max out at 90 days), you can keep topping up, but the paperwork for a proper local monthly contract requires an ARC (residence card), which is outside the scope of a visitor SIM.
So, SIM or eSIM for a remote worker?
The honest verdict for Taiwan specifically:
- Short trip (1–4 days): A [Saily](https://saily.com) eSIM alone is often enough. Skip the counter entirely, arrive connected, done.
- One to three weeks: Land on a Saily eSIM for the first hours, then pick up a Chunghwa unlimited SIM once you are settled. The eSIM handles arrival; the local SIM handles the real work at a fraction of the per-day cost.
- Signal-critical work, anywhere off the beaten track: Chunghwa, no debate. Keep the eSIM installed as a backup line, which is genuinely useful if you ever lose or damage the physical SIM.
Taiwan is unusual in that the local option is so cheap and so good that the eSIM's usual price argument mostly evaporates. What the eSIM keeps is convenience and timing, and those are worth real money at 1am in an arrivals hall. Use the eSIM to land connected, use Chunghwa to work, and you will have the fastest, most reliable setup on the island for well under $40 a month.
