 Buying a SIM Card or eSIM to Travel to Korea: What You Need to Know

Planning a trip to South Korea? One of the first things you’ll need upon arrival is reliable internet access. Whether you’re navigating the Seoul subway, translating menus, or uploading photos to Instagram, staying connected is essential. The good news? South Korea has excellent mobile coverage and several affordable options for travelers, including physical SIM cards and eSIMs.

• What’s the Difference Between a SIM and an eSIM?

A SIM card is a physical chip you insert into your phone. An eSIM, on the other hand, is a digital version that doesn’t require physical swapping—perfect for travelers who want to activate data instantly, even before landing.

• Which One Should You Choose?

Choose a SIM card if your phone doesn’t support eSIM or if you prefer a physical product.

Go with an eSIM if you want convenience, quick setup, and no need to switch out your current SIM.

• Where to Buy

You can buy a SIM card or eSIM at Incheon Airport, major convenience stores, or online in advance. Online purchases are often cheaper and easier. Here’s a recommended provider with tourist-friendly plans:
