How to Get Internet & SIM Cards
Staying connected in South Korea is super easy—and fast. This is one of the most connected countries in the world, with lightning-speed internet, even in subways and remote areas. Whether you’re checking your itinerary, ordering food delivery, or translating a menu, here’s how to stay online from the moment you land.
📱 SIM Cards vs. eSIM: What’s Best for You?
South Korea offers both physical SIM cards and eSIMs, depending on your phone. If your phone supports eSIM, that’s the easiest and fastest way to connect—no need to swap anything out.
✅ eSIM
Perfect for iPhones (XR and up), Google Pixel, and newer Samsung Galaxy phones
Purchase and activate before your trip or upon arrival—no line, no kiosk needed

✅ Physical SIM Card

🛫 Tip: If arriving at night, consider pre-ordering online and picking up at the airport OR go with an eSIM so you're connected as soon as you land.

🧠 WRUGoing Tips
Most SIMs include unlimited data, but speed may reduce after a certain GB.
Some eSIM providers also offer international roaming across Asia.
Free Wi-Fi is widely available in cafés, subways, malls, and airports—but not always secure, so avoid logging into banks or sensitive accounts on public networks.
