If you’re planning a trip to South Korea and want to stay online with ease, this guide has everything you need. Learn where and how to get the best SIM or eSIM option, how much it costs, which network providers are best for visitors, and which plan suits your travel style.
I. Where Can You Get a Tourist SIM or eSIM in South Korea? #
Travelers heading to South Korea can choose from several methods to stay connected, whether before departure or once on the ground:
1. Order a SIM Online Before You Travel #
You can purchase a prepaid Korean SIM online through international travel SIM retailers. It can be shipped to your home or available for pickup upon arrival.
- Advantages: Typically more affordable than airport vendors, and allows instant connectivity upon landing.
- Drawbacks: Requires planning ahead. If delivered in Korea, coordination is needed.
2. Buy at the Airport After You Land #
Major airports like Incheon, Jeju, and Gimpo have SIM card kiosks offering prepaid packages from major carriers.
- Pros: Convenient for immediate use.
- Cons: Often more expensive, with fewer plan choices. You’ll also need to show your passport.
3. Buy in the City #
If you’re okay waiting, you can grab a SIM in retail shops across major cities such as Seoul and Busan.
- Pros: Often the cheapest option. Local staff may help with the best package.
- Cons: May be harder to communicate if there’s a language barrier, and a passport is usually required.
4. Buy a South Korea eSIM Online #
An eSIM can be purchased and activated entirely online from providers like Roamify—no physical SIM needed.
- Pros: Simple activation, no physical delivery, and no lines or kiosks to visit.
