  1. Airport Roaming Desk

Likewise, once you’re arrived at the airport and need the SIM card urgently, it is also one of the great idea to visit the telecom roaming desk. There are different roaming desks from different telecom companies (SKT, KT, LG U+) but KT is absolutely dominant for tourist SIM for foreigners as mentioned above. Again, SKT and LG U+ is specialized more on WiFi router rather than SIM card. In case of KT roaming desk in Incheon International Airport, it’s very busy with many crowds so you may need to wait more than an hour if need to. And there, it is a bit more expensive than online.
