Purchasing a SIM card in Korea is a great option. It will give you easy and convenient access to the internet without the hassle of trying to find free WiFi. Free WiFi can often have dubious security, plus finding and logging in to each WiFi hotspot can be painful.

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.

I have done the research to help you find the best SIM card in Korea for your visit with options to pick up your SIM card from various locations throughout South Korea. This article will help you quickly decide which SIM card option will suit you best.

Before I get into the details, a key tip is to plan to pre-order your Korea 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.

You may also want to consider checking the compatibility of your phone with the relevant Korean network through Will My Phone Work.
