Can I use the Taiwan eSIM the moment I reach Taoyuan Airport?

Yes! If you install your Yeohaengyusim eSIM before leaving Korea, it links up automatically with the Chunghwa Telecom network right after landing at Taoyuan International Airport. You don't need to look for a carrier booth or a convenience store in the airport, so you can check travel information right after entering the country.

Does the internet work well all over Taiwan?

Chunghwa Telecom is Taiwan's largest mobile carrier, and it connects reliably not only in central Taipei but also at popular destinations such as Jiufen, Yehliu, Taichung, Tainan and Kenting. That said, coverage can be patchy in some mountain areas or deep valleys. It boasts 97% coverage nationwide.

Can I use a Korean charger in Taiwan's sockets?

Taiwan uses Type A/B sockets. A Korean charger (Type C plug) can't be plugged in directly, so you need to bring a multi-adapter. The voltage is 110V, unlike Korea's 220V, so be sure to check your charger's voltage range as well. Most smartphone chargers these days are 100-240V free-voltage, so an adapter alone is fine.

Are the MRT and bus apps good to use while travelling in Taiwan?

Using apps really matters for public transport in Taiwan. To use the official Taipei MRT app, Google Maps, Taiwan Trip and the like in real time, a stable data connection is essential. A Yeohaengyusim eSIM keeps you connected without interruption at LTE/5G speeds, so you can get through even complicated transfers without worry.

Which season suits a trip to Taiwan?

The ideal season for a trip to Taiwan is between October and April of the following year. It is not hot and relatively dry then, so it is pleasant for travelling. June to September, on the other hand, overlaps with typhoon season and is very humid, which can make outdoor activities hard. October, around Korea's Chuseok holiday, has good weather and the night-market atmosphere is at its best.

Does eSIM work in Taiwan?

Taiwan supports eSIM, and plans start from ₩7,519. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Taiwan?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Which carrier network does a Taiwan eSIM use?

In Taiwan it connects automatically to local carrier networks such as Chunghwa Telecom · Taiwan Mobile · Far EasTone (4G/LTE, 5G where supported). Population coverage is about 97%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I keep using my Korean number while travelling in Taiwan?

Yes. The eSIM works as a data-only second line, so your Korean SIM and number stay as they are. Use the Yeohaengyusim eSIM for data only, and keep receiving calls, texts and KakaoTalk on your Korean number.

Can I add to or extend my Taiwan eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Can I use tethering (hotspot) in Taiwan?

Yes. In Taiwan you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Taiwan. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

The buzz of the night markets, drives along winding mountain roads, and even hot-spring getaways. Taiwan is a country with a great deal to enjoy for such a short flight. From Taipei's Jiufen and Yehliu Geopark to Taichung's Rainbow Village and the beaches of Kenting in the south, it overflows with things to see and eat. There is too much moving around to be complacent just because it is a short-haul trip, and without a smartphone, everything from searching for restaurants to checking MRT lines and navigating with Google Maps is a real hassle. If you install your Yeohaengyusim Taiwan eSIM before departure, you can connect as soon as you land at Taoyuan Airport. Enjoy every moment in Taiwan to the full, with no queue for a local SIM and no worries about roaming charges.

Why you really need a travel eSIM for Taiwan

Taiwan has a well-developed public transport system, but you need a real-time internet connection to check routes and transfers. You will often combine the Taipei MRT with buses and the high-speed rail (THSR), so being able to search at any time matters. Taiwan's night markets also differ by area, such as Ralin Night Market, Shilin Night Market and Ruifeng Night Market, so you frequently need to check Google or KakaoMap before visiting. A Yeohaengyusim eSIM can be installed in Korea beforehand, so it is ready to use the moment you arrive at the airport. Running on the Chunghwa Telecom network, it covers more than 97% of Taiwan and supports both 4G/LTE and 5G speeds. You can keep your existing SIM and use the eSIM alongside it, so you won't miss calls or texts to your Korean number either. Save the time you would spend hunting for a local convenience store or an airport carrier booth, and spend it on one more plate of dim sum.
