Absolutely, you can! It's actually a super smart move to install your SouthESIM for South Korea before you even board your flight. You'll receive a QR code, which you can scan in your phone's settings while you still have a stable internet connection at home or the airport. The great news is that your data plan won't actually kick in until you land in South Korea and your phone connects to a local network. This means you'll have instant internet access the moment you touch down, ready to navigate your way from Incheon Airport!
