Your Options at a Glance

Here's a quick comparison of the three main ways to get internet in Korea. According to Korea Tourism Organization data, over 17.5 million tourists visited Korea in 2023—and most needed mobile data.

Physical SIM Cards

Korea has three major carriers: SK Telecom (SKT), KT, and LG U+. SKT offers the best nationwide coverage, especially in rural areas. KT is known for competitive pricing and offers local phone numbers. LG U+ is the budget option with decent urban coverage.

You can buy SIM cards at both Incheon Airport terminals. KT has booths at Terminal 1 (Exit E, near gates 10-11) and Terminal 2. Operating hours are 6 AM to 11 PM—if you arrive outside these hours, consider pre-ordering online.

• KT Korea SIM: 5 days unlimited data from 25,000 KRW (~$18)
• SK Telecom: 5 days unlimited from 30,000 KRW (~$22)
• LG U+: 5 days + T-money card from 27,000 KRW (~$20)

eSIM: The Easiest Option

An eSIM is a digital SIM that you activate by scanning a QR code. No physical card needed—just download before you land in Korea. Most iPhones (XS and newer) and recent Android phones support eSIM. This is our recommended option for most travelers.

Popular eSIM providers include Holafly, Airalo, Klook, and Ubigi. Prices start from $6 for 3 days up to $25 for 30 days of unlimited data. Most connect to either SKT or KT networks.

• Holafly: Unlimited data, starts at $6/day, uses SKT network
• Airalo: Data caps, cheaper at $4.50 for 1GB/7 days
• Klook: Good deals, pickup or eSIM options, from $5/day
• KT Direct: Official carrier eSIM, includes local number option

Pocket WiFi Rental

Traveling with family or need to connect multiple devices? Pocket WiFi (also called WiFi egg) lets you share one data connection with up to 5 devices. Pick up at the airport and return before departure.

Prices range from $2 to $5 per day depending on the provider. Budget option WiFi Dosirak starts at just $1.99/day with 2GB daily data. Premium options offer truly unlimited data.

• WiFi Dosirak: From $1.99/day, 2GB daily, budget choice
• KT Pocket WiFi: $3.99/day, unlimited data, reliable coverage
• SKT Pocket WiFi: $2.15/day, unlimited, up to 3 devices
• Deposit: Most require ~$50 deposit (returned at drop-off)

Where to Buy

The most convenient place is Incheon International Airport. Both Terminal 1 and Terminal 2 have carrier booths and convenience stores selling SIM cards. You can also buy at Gimpo Airport, major train stations, and convenience stores like GS25, CU, and 7-Eleven.

Which Option Should You Choose?

Your best choice depends on your travel style and group size. Here's our recommendation based on different scenarios:

• Solo traveler, short trip (3-7 days): eSIM is easiest—activate before landing
• Solo traveler, need Korean number: KT physical SIM with local number
• Family or group: Pocket WiFi to share among 3-5 devices
• Long stay (2+ weeks): Physical SIM for better value
• Budget traveler: LG U+ SIM or WiFi Dosirak pocket WiFi
• Need best coverage (rural areas): SKT network (SIM or eSIM using SKT)
