There are few ways to stay connected to the world and, more important, your family and friends when you travel to Korea.
You can rent your SIM card from Olleh KT which requires you to stay in Korea for at least 3 days before you can apply for it and to return the SIM card at the end of your trip, before you leave Korea.
Or you can rent a phone at Incheon Airport after landing, last time I checked the price was 5000 KRW/5 USD a day. The renting-plans got me confused right from the start, but if you’re interested you can check it out here.
Me and my friend even tried to buy KT Olleh 1 day wi-fi but it just didn’t work out. The payment didn’t go through no matter how many time we do it with different credit cards so we just gave up in the end.
Before coming to Seoul I did a lot of research to find an easy way to keep me connected to the internet world throughout the trip, I came across Evergreen Mobile twitter page and decided to give it a try.
I bought two SIM cards, one for me and one for my sister, we faced some problems trying to insert the SIM card too so I hope what I share below will be helpful.
