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.

If you have to go into quarantine on arrival into South Korea then ensure you check out our great options below to pre-book through Trazy a data+voice sim card for collection in the restricted quarantine area before you exit to head to your accommodation. Alternatively, Trazy also offers an international deliver service so you can receive your sim card prior to departure and you will also have your Korean phone number prior to departure.

Trazy is an online travel agency located in South Korea with whom we have partnered for several years now, and they offer a great service and are very reliable.

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.
