Selecting the best plan depends on the length of your stay and your expected data usage. We offer plans with various validity periods, including 1, 5, 7, 10, 15, and 30-day options.

• Short Trips and Light Use: If you're in South Korea for a long weekend or primarily use data for maps and messaging, smaller packages like 1 GB or 3 GB are a practical choice. These are great for staying connected without paying for data you won't use.
• Week-Long Stays: For a typical 7 to 10-day vacation, a mid-range plan of 5 GB or 10 GB is recommended. This amount of data comfortably covers regular use of social media, web browsing, and navigation apps.
• Longer Trips and Heavy Use: For stays of two weeks or more, or if you plan to stream video or use your phone as a hotspot, consider larger data allowances such as 20 GB or 50 GB. We also offer unlimited data plans for those who want maximum freedom. Note: The unlimited plans provide a set amount of high-speed data per day, after which the speed is reduced but you remain connected.

Your South Korea data eSIM connects you to the country's leading local networks, including SKTelecom and LG Uplus. This partnership ensures you receive strong and reliable network coverage in major cities like Seoul, Busan, and Incheon, as well as in most populated areas across the country.

All our eSIM plans for South Korea are data-only. They do not come with a local phone number and do not support traditional voice calls or SMS. However, you can easily make and receive calls using internet-based applications like WhatsApp, FaceTime Audio, Skype, or Telegram over your data connection.

South Korea is known for its world-class connectivity, especially in urban centers. You'll find excellent mobile data service in cities, on trains, and along major highways. However, in more remote areas like mountainous national parks or smaller islands, network coverage can be less consistent. It's a good idea to download offline maps for any planned hiking or rural excursions.

Public Wi-Fi is widely available in subways, cafes, shopping malls, and airports. Using these hotspots can help you conserve your mobile data for when you need it most. By using a data eSIM, you can keep your primary SIM card in your phone. This allows you to continue receiving calls and texts on your home number while using the eSIM for affordable local data. Services like iMessage and WhatsApp will continue to work with your existing number.
