3. Buying an eSIM at South Korea Airports: Options and Points of Sale

3.1 Official Operator Kiosks: SK Telecom, KT, LG U+

3.2 Third-Party Resellers and Automated Booths

If you only need internet access for maps, messaging apps, or browsing, a data-only plan is usually sufficient and more affordable. However, if you require a Korean phone number for calls or SMS (for deliveries or banking apps), opt for a voice + data package.
