How much does a Taiwan eSIM cost?
The cheapest option is $4.00 for 1 GB over 7 days. From there plans climb to 10 GB or more, and the bigger ones run as long as 30 days. Prices change, so instead of pasting a table that goes stale, check the live list on the Taiwan eSIM page.
Which network does a Taiwan eSIM use?
Chunghwa Telecom is the largest carrier in Taiwan and supplies the main network. If Chunghwa drops out, the eSIM falls back to Taiwan Mobile or FarEasTone, so coverage holds up in the mountains and on the east coast, not just in Taipei. 5G comes through where the local network has it; elsewhere it drops to 4G LTE, which is still fine for maps and messaging.
How much data do you actually need?
Navigation eats about 100 MB a day. Messaging and social media add another 150–200 MB. So a normal week of maps, Line and the occasional photo upload lands around 2–3 GB total. Video is the exception: an hour of streaming is roughly 1 GB. If you plan to video-call family or stream on the High Speed Rail, that changes the math.
When is unlimited data worth it?
Only when you know you’ll stream or tether. If you’re on maps and messaging, unlimited is money you won’t use. But if you’re working remotely and hotspotting a laptop every day, a larger or unlimited plan is cheaper than buying a small one and running out.
Dual-SIM: keep your bank OTPs
A data-only eSIM leaves your physical SIM slot free, so your home number keeps receiving bank verification texts at no extra cost. That’s the setup to use if your bank still sends one-time passwords by SMS.
Arrival and getting around
At Taoyuan Airport, the Airport MRT gets you into Taipei in about 40 minutes. Around the city, the Taipei Metro runs on an EasyCard, and the High Speed Rail links Taipei to Taichung and Kaohsiung in under two hours. The eSIM is active the moment you land, so you can pull up transit directions before you clear passport control.
How to install and activate
- Scan the QR code from your order email under Settings → Cellular → Add eSIM.
- Label the plan so you can tell it apart from your home SIM.
- Turn on data roaming for the eSIM once you land. The plan starts counting from the first connection.
Will my phone work with it?
Any carrier-unlocked phone that supports eSIM will work: iPhone XS or newer, Pixel 3 or newer, and Samsung Galaxy S20 or newer are the common ones. If your phone is locked to a carrier, unlock it first or the install will fail at the QR step.
Frequently Asked Questions About Taiwan eSIMs
Q1: Do I need to register with a passport?
No. Tourist data plans don’t ask for a passport upload or ID check under current carrier rules. Local laws can change, so it’s worth a quick check before you go.
Q2: Which network does the eSIM connect to?
Chunghwa Telecom is the primary network, with Taiwan Mobile and FarEasTone as backup. Your phone picks whichever has the strongest signal in that spot.
Q3: Can I use it as a hotspot?
Yes, hotspot and tethering are enabled on every plan. A laptop or a second phone can share the connection.
Q4: When does the plan start counting?
From the first connection to a local network after landing, not from the moment you scan the QR code. Install it at home on Wi-Fi and activate on arrival.
Q5: Does it work outside Taipei?
Yes. The same networks cover the whole island, including Hualien, Taitung, Alishan and the offshore islands, so you stay connected when you leave the capital.
Q6: Can I top up or extend it?
Topping up depends on the plan. The simplest option is to buy a longer plan up front if your dates are fixed; check the live plan list for what’s available.
Q7: What if I run out of data?
Buy a second plan and install it the same way. The first one keeps working until its days or its data run out, whichever comes first.
Q8: Does it work with Line, WhatsApp and FaceTime?
Yes. Calls and messages through Line, WhatsApp, FaceTime or Zalo run over data, so you don’t need a local number.
Q9: Will I get 5G everywhere?
5G appears where the local network has it — mostly cities and major transport lines. In between you’ll sit on 4G LTE, which handles navigation and messaging without a problem.
Q10: What’s the refund policy?
Refunds depend on whether the plan has been activated. If you buy and don’t install it, you’re usually covered; once it’s active, it’s non-refundable. The full terms are on the product page.
Bottom line
For a Taiwan trip, a single data eSIM on Chunghwa Telecom is the least-fuss option, and 2–3 GB covers a normal week. Pick the size that matches your video habit, install it before you fly, and you’ll have signal the moment you land. See the current plans here.
