Which Taiwan eSIM brand to pick in 2026, compared for 5 to 10 day trips
A comparison of the eSIM brands that work in Taiwan, from daily-cap plans to unlimited ones, with sizing for 5 to 10 day trips and a note on airport SIMs at Taoyuan.
Trả lời nhanh
- Taiwan runs on Chunghwa, FarEasTone and Taiwan Mobile, and almost every eSIM brand uses one of them, so the real difference between brands is the plan model.
- A 5 to 10 day trip typically uses around 1 to 2GB a day, so fixed-GB or daily-cap plans are enough, and unlimited suits people who share a hotspot heavily.
- A SIM from a Taoyuan airport counter means a queue and passport registration after immigration, while an eSIM can be installed before the flight and works on landing.
How this comparison was made
This comparison is based on each brand's published plans, policies and help pages as of October 2026, not on a test trip. Prices change weekly, so none are quoted here. Check the current price for your exact dates.
This site also sells eSIMs. On our store Taiwan is covered by regional and global packages, and there is no Taiwan-only plan. The related guides below explain how to choose between those packages.
Taiwan networks and the 3G question
Taiwan has three main operators: Chunghwa Telecom, FarEasTone and Taiwan Mobile. Our plan pages list which network each plan uses, and with other brands you should look on the product page too, since some do not say which operator they connect to.
Reports say Taiwan's 3G network was switched off at the end of 2018, leaving 4G and 5G only. We could not confirm this on an official page, but any phone that supports eSIM already runs on 4G, so it should not affect most travellers.
Brands compared for Taiwan
| Lựa chọn | Plan model | Điều đáng biết | Kiểm tra trước khi mua |
|---|---|---|---|
| Airalo | Prepaid country, regional and global packages, mostly data only | Unlimited plans drop to 1 Mbps after 3GB in a day. There is a Thai-language website | Whether Taiwan is on the package's country list, and when validity starts |
| Holafly | Sold by number of days with unlimited data, data only | A fair-use clause applies, hotspot limits vary by destination, and top-ups ended in October 2026, so more days means a new plan | The hotspot terms on the Taiwan page |
| Nomad | Fixed-GB packages, Unlimited plans and Day Plans | Day Plans are meant for trips of 10 days or less, Unlimited plans are non-refundable, and there is a Thai help centre | Whether Taiwan is among the Day Plans countries |
| Saily | App-based, priced in US dollars, with shared plans for up to 4 people | The app has no Thai language, and the website blocks automated readers, so some details are only confirmed from the App Store | Refund terms and when the plan starts counting |
| AIS SIM2Fly | AIS travel SIM sold as an eSIM, usable by customers of any Thai network, with a separate prepaid number | The China pack covers Mainland China, Taiwan, Hong Kong and Macau. Days count from the first data connection abroad, and Thai ID is needed to register | It must be used abroad within 60 days of opening |
| True GO Travel MyPlan | An eSIM where you pick countries, days and data, open to any Thai network, on a separate TrueMove H prepaid number | Face scan and Thai ID are required, speed falls to 128 Kbps after the quota, and no calls or SMS are included | It must be used abroad within 60 days of scanning the QR |
| esimonline | Sold in baht, no app needed, QR by email, data only with no phone number | Support in Thai, English and Chinese, and a self-service refund within 14 days if the eSIM has not been installed | Taiwan comes through regional or global packages, and the plan page lists the networks |
Sizing a 5 to 10 day trip
Taiwan has trains, buses and ride apps that all need data, and a typical trip uses around 1 to 2GB a day. Match the plan model to how you actually use your phone.
- Fixed GB for the whole trip: fine for light use such as maps and translation. It often covers 5 days, but watch how fast you burn through it
- Daily cap: easy to budget and suited to trips up to 10 days, for example Nomad Day Plans. Check what speed you get once the daily quota runs out
- Unlimited: for people who film, stream or share a hotspot with others. Every brand has a normal-use ceiling, so read where the slowdown starts
On a 7 to 10 day trip that adds another country alongside Taiwan, a regional package is often simpler because you do not switch profiles midway.
Airport SIM at Taoyuan versus an eSIM
Taoyuan airport has counters from Chunghwa Telecom, Taiwan Mobile and FarEasTone in the arrivals hall. You clear immigration, collect your bag, pass customs and only then buy, with your original passport for registration. Queues can form when several flights land together.
An eSIM can be installed at home before the flight and switched on at arrival, so you can message your hotel or open a ride app straight away. A counter SIM still makes sense for anyone whose phone does not support eSIM.
Entry rules and what to keep in mind
- A data-only eSIM has no phone number, so keep your Thai SIM in the phone for bank OTP texts
- Install before flying, then check that mobile data is set to the eSIM and that data on the Thai SIM is off
Câu hỏi thường gặp
Câu hỏi thường gặp
Which Taiwan network is best?+
We have no official source for ranking the networks. Chunghwa, FarEasTone and Taiwan Mobile are all major operators. See whether the plan names its network, and choose the brand by plan model instead.
How many GB for 7 days?+
Plan on roughly 1 to 2GB a day. Maps and chat sit at the low end, while streaming or hotspot sharing pushes you up, or you can pick a daily-cap plan that refreshes every day.
How early can I buy an eSIM?+
It depends on the brand. Nomad needs activation within 60 days, SIM2Fly and GO Travel must be used abroad within 60 days, and Airalo states no fixed deadline. Read the terms of the plan you choose.
