Zwitchy eSIM Data Plans for South Korea

Zwitchy does not provide a truly unlimited data eSIM for South Korea. The plans that contain “Unlimited” in their name actually offer a fixed amount of high‑speed data each day, such as 1 GB/day or 3 GB/day, with speed reduced to 1000 kbps once that daily limit is reached. Travelers who need more data without such caps can choose one of Zwitchy’s fixed‑data plans: for example, the South Korea 50 GB · 30 days plan for $38.00 USD or the South Korea 30 GB · 30 days plan for $24.00 USD. These alternatives provide a larger, unthrottled data allowance over the validity period.

Zwitchy does not provide an eSIM for South Korea that includes a phone number or SMS capability. Only data‑only eSIMs are offered by the provider. Travelers who need to communicate from the device can generally rely on VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but should confirm that these services are accessible in South Korea before purchasing a plan.

Zwitchy offers 16 single‑country plans and 29 multi‑country plans for South Korea. The catalog includes both fixed data‑cap plans, where the allotted data is available for the full validity period, and daily data‑cap plans, where the allowance resets every day. Prices range from about $1.00 to $139.50, with data caps spanning from 100 MB up to 50 GB.
