South Korea: SIM card with SKT unlimited data & calls

Summary

Landing in Seoul & getting my SKT SIM: a real-life travel fix

From your first steps in Incheon or Gimpo Airport, you’ll get your South Korea SIM card sorted fast — with unlimited 4G/LTE data and local calls ready to go. Friendly staff walk you through activation, so you can message friends or use hotspot sharing right away. It’s one less thing to worry about on arrival — and honestly, that little moment of connection is something you’ll remember long after landing.

What’s the experience like?

Stepping off the plane at Incheon, I was still half-asleep and honestly just wanted coffee. Instead, I found myself following the signs for the SKT Roaming Center — near Exit F, Terminal 1. The arrivals hall was buzzing, that mix of rolling suitcase wheels and families greeting each other in bursts of Korean. The guy at the counter smiled when I handed over my passport (I fumbled it a bit), and he explained how to activate my SIM card online. He even pointed out where to sit for Wi-Fi if I needed it right away — which I did, because my phone stubbornly refused to cooperate at first.

The process took maybe fifteen minutes, including me double-checking the contract number and SIM phone number (don’t lose that slip of paper). My hands were still cold from the flight, but once the SIM was in and verified, everything just worked — LTE bars popped up instantly. There’s something weirdly comforting about seeing your phone light up with Korean networks after a long haul. I messaged my friend Jihoon to say I’d landed safely; he replied with a selfie from Jeju and told me to try “bingsu” before leaving Seoul. Li laughed when I tried to pronounce it in Mandarin — probably butchered it.

I used hotspot sharing on the train into town so my travel buddy could check maps too. We kept switching between Naver Map and Kakao Map trying to find our Airbnb (pro tip: both are lifesavers here). The city outside looked washed in pale winter light, all glass towers and those tiny street food stalls puffing steam into the air. By afternoon we’d already used the unlimited data streaming K-pop videos while waiting for our luggage at Shinsegae Centum City — not exactly what I planned, but hey, it worked.
