Universal SIM Card in Korea – USIM
In Korea, it is very easy to purchase a domestic SIM card, commonly known as a USIM, which allows you to use mobile data, make calls, and send messages during your stay. These USIM cards are widely available at convenience stores such as GS25, CU, and 7-Eleven, making it convenient for travelers to stay connected almost anywhere in the country.
Alternatively, you can rent a portable WiFi router, often called an “Egg,” at the airport arrival hall. This is a great option if you are traveling with friends or family, as multiple devices can connect to one router at the same time.

Staying connected while traveling in Korea is very helpful, as you can easily use maps, translation apps, public transportation apps, and search for restaurants, cafes, shopping areas, and tourist attractions.
Korea has an excellent public transportation system, vibrant shopping districts, historic palaces, modern architecture, and delicious food, making it a very convenient and exciting destination for international travelers.
