Best SIM Card, eSIM and WiFi for South Korea Travel – Updated 2024

It’s hard to imagine traveling in a foreign country without the internet these days. Although South Korea provides free internet services in public places, you will definitely need to access the internet during your trip. However, finding the best SIM card or WiFi is not easy. Comparing the options of SIM cards and WiFi is an almost impossible mission for ordinary people.

Fortunately, I worked for a telecommunication company in South Korea for a long time. So I did your homework for you. I investigated all the SIM card, WiFi, and eSIM product options of multiple service providers.

Some companies say they provide unlimited 4G internet access. However, the products provide 128kbps, which is almost unusable in this multimedia world after the data of the 4G speed is used up. Staying connected during your travel to Korea shouldn’t have to be complicated. Here are the best ways to do so.

So I compiled and compared prices and options of SIM, eSIM, and Wifi products for your trip to South Korea. It took over a week to make this spreadsheet. You can easily find your perfect-fit product at the best price. Check it out!
