The South Korea plans in our database use SK, LG. Where a provider hasn't published it, the table shows "Network not published". Coverage is excellent across South Korea, including the Seoul subway. A data-only eSIM can't receive Korean SMS verification codes.
For maps, messaging and light browsing, about 0.3–0.5GB a day, so 3–5GB is enough for 7 days. If you often watch videos or share a hotspot, consider unlimited data. To save money, choose Airalo 50GB · 30 days, the best value per GB (US$0.98 / GB).
Most providers don't list hotspot limits in their details, so please read the plan details before you buy. A travel eSIM is data only and works alongside your own SIM, so WhatsApp keeps working. Calls and SMS to your usual number still go through your own carrier (roaming charges may apply).
A data-only travel eSIM has no Korean phone number, so it can't receive SMS verification codes from Korean websites or apps.
