You'll use data all day for maps, tickets and translation. Korea makes it easy with three options; sort it out before you land or at the airport.
Step by step

- Physical USIMSold at airport roaming centers, convenience stores (CU, GS25, 7-Eleven, Emart24) and online for airport pickup.
- Pocket Wi-Fi (Wi-Fi egg)Rent one at an airport roaming center. Handy if friends share it.
- Airport roaming centersMajor airports have counters run by KT, SK Telecom and LG U+ for SIMs, Wi-Fi rentals and roaming.
- Think about text messagesSome Korean services send codes or winner notices by text. If you plan to use them, check whether your plan includes a phone number.
