Compare South Korea eSIM Plans

The South Korea eSIM comes in ten sizes. For 3 days: 10GB at A$7.90. For 7 days: 10GB at A$8.90, 20GB at A$15.90 and 30GB at A$21.90. For 15 days: 10GB at A$9.90, 20GB at A$17.90 and 30GB at A$24.90. For 30 days: 10GB at A$10.90, 20GB at A$18.90 and 30GB at A$25.90. Prices are in Australian dollars and convert automatically if you shop in another currency. Both plans are delivered by email as a QR code, and neither can be recharged, so choose the allowance that fits your whole trip.

Which South Korea eSIM Should I Choose?

Weekend or stopover in Seoul: 10GB (3 Days)

For a long weekend around Myeongdong, Hongdae and the palaces, the South Korea eSIM 10GB (3 Days) plan at A$7.90 covers maps, translation, ride-hailing and messaging with room to spare. Staying up to a week costs only a little more: the 10GB (7 Days) plan is A$8.90.

One to two weeks, Seoul to Busan: 20GB (15 Days)

A classic first trip takes in Seoul, Gyeongju and Busan by KTX, perhaps with a few days on Jeju. The 20GB (15 Days) plan at A$17.90 gives you enough for constant navigation, camera translation of menus and daily photo uploads. If your trip is a week or less and you use a lot of data, the 20GB (7 Days) plan is A$15.90.

A month in Korea: 30GB (30 Days)

Language courses, working holidays and slow travel suit the 30-day plans. Light users can take 10GB (30 Days) at A$10.90, while the 30GB (30 Days) plan at A$25.90 is the better fit if you tether a laptop or stream on the move. The plan cannot be topped up, so size up if you are unsure.

Korea plus Japan, Taiwan or Southeast Asia: Asia Explorer

If South Korea is one stop on a wider itinerary, the Asia Explorer eSIM covers South Korea on the LG U+ network along with 11 other destinations. The 20GB Data (15 Days) plan is A$25.90 and the 10GB Data (30 Days) plan is A$15.90, and a 3GB Data (3 Days) option at A$5.90 suits a short stopover.

South Korea Network Coverage: LG U+

South Korea has three national mobile operators: SK Telecom, KT and LG U+. Our South Korea eSIM connects to LG U+, with 5G where it is available and 4G LTE elsewhere. The Asia Explorer eSIM also uses LG U+ while you are in South Korea. Neither plan uses SK Telecom or KT, so if you specifically need one of those networks, these are not the plans for you.

Coverage is nationwide and takes in Seoul, Busan, Jeju and the KTX rail corridors. South Korea is one of the most densely connected countries in the world: the Seoul and Busan subway systems have mobile signal in stations and on trains, and you can expect service in the cities, at the airports and along the main expressways. Signal can be weaker or patchy on mountain trails in national parks such as Seoraksan and Jirisan, on Hallasan on Jeju, and on some of the smaller offshore islands. Download offline maps before a long hike. For ideas outside the capital, see our guide to travelling Korea beyond Seoul.

Travelling Beyond South Korea?

The South Korea eSIM works in South Korea only. For a multi-country trip, the Asia Explorer eSIM covers 12 destinations on one QR code: South Korea, Japan, Taiwan, Hong Kong, Macau, Vietnam, Thailand, Malaysia, Singapore, Indonesia, Australia and New Zealand. It is data only, supports hotspot, and plans run from 3GB for 3 days to 50GB for 30 days. No ID is required for activation, except that travellers to Hong Kong and Taiwan must complete real-name registration with a valid passport.

If you would rather buy a dedicated plan for each stop, compare our Japan eSIMs, Taiwan eSIMs and Hong Kong and Macau eSIMs, or browse every regional option in the Asia eSIM collection.

How It Works

1. Buy online. Choose your data size and validity. The QR code is sent by email. Returning customers get real-time delivery, and orders placed after 1 AM AEST are sent from 9 AM AEST.
2. Install on Wi-Fi before you fly. The South Korea eSIM can be installed any time before your intended travel date. Scan the QR code in your phone's mobile settings while you have a reliable Wi-Fi connection. The QR code must be installed and used within 90 days of purchase and cannot be reissued.
3. Land and connect. When you arrive, set the eSIM as your mobile data line and turn on data roaming for it. Service starts on the first network connection, and your 3, 7, 15 or 30 days run from that activation date.

Screenshots and troubleshooting steps are in the South Korea Prepaid eSIM User Guide. Our Melbourne-based support team is available 16 hours a day by live chat and email if you get stuck. The Asia Explorer eSIM follows a different rule: install it on arrival at your destination rather than in advance, because its service starts on the first network connection in any of its 12 destinations. Details are in the Asia Explorer user guide.

South Korea eSIM vs Roaming on Your Home Plan

Roaming with your home carrier is convenient, but it is usually charged per day or per megabyte, often with a small daily allowance and reduced speeds once that allowance is gone. The cost grows with the number of days you are away rather than how much you actually use, and it is easy to trigger a charge by accident when a background app refreshes.

A prepaid South Korea eSIM is a fixed price for a fixed allowance. You pay once, you know exactly how many gigabytes and days you have, and there is no bill afterwards. If your phone supports dual SIM, your home SIM stays active for incoming calls and SMS codes from your bank (keep data roaming switched off on it), while the eSIM handles mobile data on a Korean network. The trade-off is that the plan has no Korean phone number and no voice calls or SMS, so calls are made through apps. A local Korean prepaid SIM can give you a local number, but it generally involves passport registration at a counter, which this travel eSIM does not.

Tips for Using an eSIM in South Korea

• Check that your phone is unlocked and supports eSIM before you buy. Dial *#06#: if a 32-digit EID appears, the device supports eSIM. You can also consult our eSIM compatibility list.
• Install Naver Map or KakaoMap before you land. Google Maps has long offered only limited navigation in South Korea, and locals rely on the Korean apps for walking, transit and driving directions. Both work in English.
• KakaoTalk is the everyday messaging app in Korea. Guesthouses, tour operators and restaurants often use it, and it handles voice and video calls over data.
• Papago is a popular translation app for Korean, with a camera mode for menus and signs. Download the offline language pack on Wi-Fi to save data.
• Public transport runs on stored-value cards such as T-money, which you can buy and top up at convenience stores and subway stations without a local phone number.
• Some Korean apps and websites, including several food delivery and booking services, ask for a Korean phone number to verify your identity. A data-only eSIM cannot provide one, so ask your accommodation for help or use services that accept foreign visitors.
• Set the eSIM as your mobile data line and switch off data roaming on your home SIM so you are not charged twice.
