Korea SIM Card & eSIM Guide for 2025 Travelers

Traveling to Korea in 2025? One of the first things you’ll need is reliable internet access. Whether you’re navigating the subway, translating signs, or sharing your trip on social media, a SIM card or eSIM is essential. This guide explains everything you need to know about getting a SIM card or eSIM in Korea – including prices, where to buy, and tips for staying connected.

>Korea SIM Card & eSIM Guide

1. Why you need a SIM card or eSIM in Korea

Korea has some of the fastest internet speeds in the world, but public Wi-Fi isn’t always reliable. Many cafes, hotels, and subways offer free Wi-Fi, but you’ll constantly need passwords, and coverage isn’t guaranteed. A Korea SIM card or eSIM gives you unlimited data access for navigation, messaging, and essential apps like KakaoMap or Naver Map.

2. Where to buy a SIM card in Korea

The easiest place to buy a SIM card is at the airport (Incheon, Gimpo, or Busan). Major telecom providers – KT, SK Telecom, and LG U+ – have booths in arrival halls. You can also pre-order online and pick up your SIM card when you land. Prices range from 25,000–40,000 KRW for 7 days of unlimited data, and 50,000–70,000 KRW for 30 days.

3. How to use an eSIM instead

If your phone supports eSIM (most newer iPhones, Samsung Galaxy, and Google Pixel models do), you can skip the physical SIM card. Purchase an eSIM online before your trip – companies like Airalo, Nomad, and KT offer Korea eSIMs – and simply scan a QR code to activate it. This option is perfect for travelers who don’t want to swap out their home SIM card.

4. Documents you might need

For short-term tourist SIMs, you usually don’t need a passport copy – just present your passport at the counter. For long-term plans (over 90 days), you may need an Alien Registration Card (ARC). Most travelers will be fine with prepaid tourist SIMs or eSIMs.

5. Tips for staying connected in Korea

Check compatibility: Make sure your phone is unlocked before traveling. ✅ Top-up options: Some SIM cards allow you to recharge at convenience stores or online. ✅ Hotspot sharing: If you’re traveling in a group, consider one unlimited data SIM and share via hotspot. ✅ Watch for expiration: Some tourist SIMs deactivate after a set period (7, 15, or 30 days).


Conclusion: Stay connected, travel smarter

Getting a SIM card or eSIM is one of the smartest things you can do when visiting Korea in 2025. With unlimited data on your phone, you can navigate the country, use local apps, and stay in touch with ease.
