Why Purchase a Korean Sim Card?

Many accommodation options have guest WiFi, but when you walk out the door you will not have cost effective access to data – and you really need it for a whole range of reasons including using public transport timetables, platforms and stations; as well as for using map apps like Naver Map and KakaoMap to get around. Google Maps has pretty limited usefulness in South Korea.  Check out our article on the best apps to load onto your phone for your trip to South Korea.

We have done the research to help you find the South Korea Sim Card for your visit with options to pick up your Sim card from various locations throughout South Korea or have it delivered to your home prior to departure. This article will help you quickly decide which Sim card for Korea option will suit you best.

Before we get into the details, a key tip is to plan to pre-order your South Korea prepaid Sim card with many providers allowing you to pre-order up to 1-3 days in advance. Also, if you are arriving or departing early or late, ensure you check the opening hours for your pick up and return options which are further down in the article, or on the supplier’s page after you click through below.

For prepaid eSim plans you should receive your eSim details either instantly, or within 24 hours of placing your order, so this is a much faster option if your phone is a newer phone. Make sure you check before booking whether your cell phone can be used with an eSim, as only newer phones have this feature.
