Firsty eSIM Data Plans for South Korea

Firsty does not provide an unlimited data eSIM plan for South Korea. All of the current South Korea offerings from Firsty have a fixed data allowance of 5 GB per day, as seen in plans such as the Firsty First Class (South Korea) – 1 day, 3 days, 5 days, 7 days, and 10 days.

Travelers who need more data can consider purchasing one of these fixed‑data plans. For instance, the Firsty First Class (South Korea) – 3 days plan gives 15 GB of data over its validity period, and the 10 days plan offers 50 GB. Because the cost increases with the number of days, buying a higher‑day plan can be more cost‑effective for heavy users, whereas a single day plan may suit lighter usage.

Firsty does not provide an eSIM for South Korea that includes a local phone number or SMS capability. Only data‑only eSIM plans are available from Firsty for this destination. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without a traditional phone number or SMS service.

Firsty offers 16 single‑country data plans for South Korea, with no multi‑country options available. Prices range from $2.15 to $107.69, while data caps span 1.5 GB to 5 GB. Of these 16 plans, 14 feature daily data caps that reset each day, allowing travelers to control how much data they use each day, whereas 2 provide a fixed data amount that does not reset, giving a consistent data allowance for the entire validity period. This variety allows users to choose the plan that best matches their expected data usage during their stay.
