Best eSIM for Taiwan

For most trips, buy a data eSIM before you fly and install it at home. Our Taiwan plans are unlimited daily. Full speed up to 1 GB per day, then up to 1 Mbps, at $12.60 for three days and $29.40 for a week. Airalo's Taiwan plans start at $4.00 for 1 GB over 3 days, its unlimited plans run from $12.50 for three days to $69 for a month, and Holafly runs $12.50 for three days up to $73.90 for thirty. If you just need maps, messaging and a translation app, the 1 GB per day tier is enough and you do not pay for a bigger daily cap.

Two exceptions, and we would rather say them plainly than sell you the wrong thing. If you genuinely need unlimited data for a full month, Airalo's monthly plan undercuts our unlimited tier and you should buy theirs. And if you need a Taiwanese phone number, no data eSIM from anyone will give you one. That second point causes more trouble in Taiwan than in almost any country we cover, so it gets its own section below.

Taiwan runs on phone numbers. YouBike, the bike share system you see on every corner in Taipei, requires a Taiwanese number to register. So do Line Pay, most local delivery apps, and a lot of e-commerce and banking verification. A data only eSIM, ours or anyone else's, gives you internet but no number, so those services stay closed to you.

It gets stranger. Travellers on the Taiwan subreddit report that regional travel eSIMs sometimes geolocate outside Taiwan, one visitor found the YouBike app failing with a network error while his phone showed a healthy 5G connection, because the eSIM was placing him in Japan. He solved it with a VPN. If you plan to use apps that check your location as well as your connection, buy a Taiwan specific plan rather than a regional Asia bundle, which is the single most useful piece of advice on this page.

If a local number is essential to your trip, buy a prepaid tourist SIM from Chunghwa, Taiwan Mobile or Far EasTone with your passport. It is the only route to a Taiwanese number, and we will not pretend otherwise.

Taoyuan and Songshan both have SIM counters in arrivals, and their tourist packages are decent value at around 1,000 NT. The catch is opening hours. Travellers arriving after midnight repeatedly report the kiosks closed until roughly 6am, and the Klook pickup desk shut with them. Late arrivals end up choosing between waiting in the terminal until morning or heading into the city with no data.

An eSIM installed before departure removes the decision. Your phone connects as the plane doors open, you book a taxi or check the MRT timetable straight away, and you can still buy a local SIM later in the week if you decide you need a number.

Taiwan has three major carriers: Chunghwa Telecom, Taiwan Mobile and Far EasTone, plus smaller players. Chunghwa reaches well into rural areas, Taiwan Mobile is strong in the west coast cities where most visitors spend their time, and all three run solid 5G in Taipei, Taichung, Tainan and Kaohsiung.

Our Taiwan data plans connect through Taiwan Mobile, with Chunghwa Telecom and Far EasTone available as fallbacks on the same profile, verified in August 2026. That matters because network claims in this category are often copied from marketing sheets rather than checked. One honest note from Taiwanese travellers: the very cheap resold eSIMs sold through booking platforms sometimes ride heavily congested capacity, and users report speeds far below what the underlying carrier is capable of. Cheap and slow is a real combination in Taiwan.

Prices checked by hand on 30 September 2026. Holafly sells Taiwan as unlimited only, and so do we, so the table compares unlimited against unlimited.

Read that table honestly. Our column is the 1 GB per day tier, and there is a 2 GB per day tier above it if you want a bigger daily cap. On short unlimited we are competitive. On month long unlimited, Airalo and Holafly beat us and we are not going to pretend they do not.

A local prepaid SIM from an airport counter sits at roughly 1,000 NT for a tourist bundle, which is fair value if you want a number and do not mind the queue and the passport paperwork.

Taiwan is a heavy maps and translation country, and light on everything else, because free wifi is genuinely everywhere. Convenience stores, MRT stations, most cafes and nearly every hotel put you on wifi without asking for a local number.

A long weekend in Taipei on maps, Line and a translation app fits comfortably inside the 3 day plan at 1 GB per day, which is $12.60. A week or two mixing Taipei with Tainan, Kaohsiung or Hualien suits the 7 day plan at $29.40 or the 15 day plan at $63.00. If you are posting video from Jiufen and Taroko every evening, or hotspotting a laptop, take the 2 GB per day tier, which is $56.84 for a week.

Long stay students and exchange visitors are the group who should think hardest. Chunghwa stores have told visitors without an ARC that they may hold only one 30 day prepaid plan and cannot simply renew it, which leaves people scrambling in month two. A travel eSIM sidesteps that entirely, because it is not a Taiwanese subscription and can be re-bought as many times as you like.

The west coast corridor is excellent. Taipei, Taoyuan, Hsinchu, Taichung, Tainan and Kaohsiung all have dense 5G, and the high speed rail line keeps a signal for nearly the whole run. The Taipei MRT has coverage in stations and tunnels.

The east coast and the mountains are the honest exception. Hualien and Taitung towns are fine, but Taroko Gorge, the cross island highways and the high altitude sections around Alishan have real dead spots on every carrier. Download offline maps before you head into the gorge, the same way locals do.

One quirk worth knowing: some restaurants and night market stalls use QR menus hosted on services that load slowly over congested resold data. If a menu will not open, that is usually the network side rather than your phone.

Buy on wifi at home, scan the QR code we email you, and leave the line switched off until you land. On an iPhone go to Settings, then Cellular, then Add eSIM. On most Android phones go to Settings, then Network and internet, then SIMs, then add a SIM. It takes about two minutes.

When you land at Taoyuan, switch on data roaming for the eSIM line and turn data off on your home line. The phone finds Taiwan Mobile within a minute or two and you are online before passport control. Your home number stays active for calls and bank codes.

Taiwan rewards a little planning. Land connected, use the island's excellent free wifi for the heavy lifting, and keep a data plan for maps and translation when you are out. A month at 1 GB per day is $126.00 and that covers almost every itinerary, and if your trip needs a Taiwanese phone number for YouBike or Line Pay, add a local prepaid SIM when you reach the city rather than buying the most expensive thing at the airport at midnight.

Have a great trip. The night markets are worth every gigabyte of photos.
