📱 Stay Connected in Korea — 2025 SIM Card Guide

Staying connected while traveling in Korea has never been easier. Whether you’re visiting for a few days or several months, this 2025 guide explains everything you need to know about getting a SIM card, eSIM, or Wi-Fi device in Korea.

🇰🇷 Major Korean Mobile Carriers

There are three main mobile service providers in South Korea:

  • SK Telecom (SKT) – The largest provider with excellent nationwide coverage.
  • KT (Olleh) – Offers stable and fast connections, popular among travelers.
  • LG U+ – Affordable and has solid data speeds, great for city areas.

All three carriers offer tourist SIMs and short-term eSIM plans that can be purchased both online and at the airport.

✈️ Where to Buy a SIM Card in Korea

1️⃣ At the Airport (Incheon or Gimpo)

Most tourists buy their SIM cards at Incheon International Airport Terminal 1 or 2. Look for counters from KT, SKT, or LG U+. Staff usually speak English, and installation takes about 5 minutes.

2️⃣ Online Pre-Order

You can pre-order your SIM online via platforms like Trazy, Klook, or KKday. Upon arrival, pick it up at the airport counter. Some options include eSIM activation by QR code, allowing instant setup.

3️⃣ Convenience Stores

CU, GS25, and 7-Eleven sell prepaid SIMs from KT or LG U+. However, foreign tourists may find setup easier through airport counters or online services.

📶 SIM Card vs eSIM vs Pocket Wi-Fi

Here’s how to choose the best option for your needs:

  • SIM Card: Works in any unlocked phone; available for 3, 5, 10, or 30 days.
  • eSIM: Digital version — no physical card. Perfect for newer iPhones and Androids.
  • Pocket Wi-Fi: Great for groups or travelers with multiple devices. Battery-powered and shareable.

Prices range from ₩5,000 (1-day) to ₩60,000 (30-day unlimited data) depending on speed and provider.

🧳 What You Need to Bring

  • Passport (required for registration)
  • Unlocked phone (SIM-locked devices won’t work)
  • Payment method (credit card or Korean won)

Once activated, you’ll receive your Korean phone number and can use high-speed 4G/5G data immediately.

💡 Travel Tip for 2025

Most modern SIMs now offer tethering and hotspot sharing, so you can connect laptops or tablets. For frequent travelers, eSIMs from Airalo or Nomad are convenient and can be recharged online without visiting a store.

💬 Frequently Asked Questions

1. Do I need to show my passport to buy a SIM in Korea?

Yes. All SIM card purchases by foreigners require passport registration, even for short stays.

2. Can I use my foreign SIM for roaming instead?

You can, but roaming is more expensive. Local SIM or eSIM plans are cheaper and faster for data use.

3. Is 5G available for tourists in Korea?

Yes. Most tourist SIMs from SKT, KT, and LG U+ include access to 5G networks at no extra cost.

4. What if my phone doesn’t support eSIM?

You can still buy a physical SIM card at the airport counter. Staff will help install and test it for you.
