Why go with an eSIM
Skip the line for a physical SIM card or pocket Wi-Fi at Gimhae Airport. The moment your flight lands, you’re online for navigation, ride-hailing, and checking subway routes — especially handy for tightly packed trips of 3 days or more. It runs on the SKT and LG U+ networks, and iPhone users can install it with one tap in the KKday app, no QR code needed.
If you’d like to compare more data and duration options, it’s worth checking Klook too — plans run from 1 to 30 days, with daily data from 600MB up to unlimited, backed by over 90,000 reviews.
Things to check before you go
- Confirm your phone supports eSIM (most recent iPhones and some Android flagships do)
- Install the eSIM profile before you leave home, then activate it once you land in Korea — unstable local networks can make installation tricky after arrival
- Choose a plan that matches your actual trip length; some plans also support hotspot sharing
- An unscanned eSIM stays valid for 180 days, but once scanned it expires automatically if not activated within 30 days
- Both KKday and Klook eSIMs are non-refundable and can’t be cancelled or changed once purchased — confirm your travel dates before you book
