How Unlimited Data Works in South Korea
South Korea Unlimited Data Plans provide unlimited mobile data in South Korea with a high-speed data allowance for each 24-hour period. The amount of high-speed data depends on the plan level you select.
After the high-speed allowance is used, unlimited data remains available at reduced speeds until the next 24-hour period begins, when the high-speed allowance becomes available again. For full details, review the Fair Usage and Expiry Policy.

Unlimited or Fixed Data for Your South Korea Trip?
South Korea is supported by both South Korea Unlimited Data Plans and South Korea Fixed Data Plans. The better option depends on how you prefer to use mobile data while travelling.
| Feature | Unlimited Data | Fixed Data |
|---|---|---|
| Best for | Travellers who want ongoing mobile data access throughout their trip | Travellers who prefer a defined high-speed data balance |
| Data | Unlimited data with a high-speed allowance for each 24-hour period | Choose from 3GB to 30GB of high-speed data |
| How usage works | After the high-speed allowance is used, data continues at reduced speeds until the next 24-hour period begins | Use your selected high-speed data balance until it is used or the plan validity period ends |
| Useful for | Regular daily connectivity, longer stays, multi-city trips, hotspot use, and travellers who prefer not to manage a remaining GB balance | Trips where you have a good idea of how much high-speed data you expect to use |
Using Mobile Data During Your South Korea Trip
Mobile data can make it easier to stay connected throughout a South Korea trip, whether you are visiting for a vacation, business trip, family visit, or longer stay. Popular destinations such as Seoul, Busan, Incheon, Jeju Island, Gyeongju, and Daegu may all feature in different itineraries, so having mobile data available as you move between accommodation, airports, railway stations, transportation, attractions, restaurants, meetings, and other travel arrangements can be especially convenient.
- Getting around: Keep maps, rail and transportation details, accommodation information, reservations, and travel documents available while you are on the move.
- Multi-city and longer trips: Stay connected as your itinerary takes you between different parts of South Korea without relying entirely on hotel, airport, railway station, restaurant, or public Wi-Fi.
- Business travel: Stay connected to email, browser-based services, messaging, video meetings, and other online tools while travelling.
- Hotspot and router use: Share your mobile data connection with a laptop, tablet, or another device, or use the SIM Card in a compatible unlocked travel router.
Your South Korea SIM Card can connect to supported partner networks including LGU [4G/5G] and SK [3G/4G/5G]. Network availability depends on your location, device, and local network conditions.
