  5. Check validity: many eSIM plans expire by time, not data used.


Conclusion

For convenience and data-only needs, a well-known eSIM—like AloSIM or Yoho Mobile—is the easiest. If you need local voice/SMS, opt for a physical SIM from LG U+, SK T, or KT at the airport. Remember to activate before heading out, and enjoy fast and reliable connectivity during your stay! Variations may occur depending on location and season—please treat this as a guideline.
