Zwitchy eSIM Data Plans for South Korea

Zwitchy does not offer a true unlimited data eSIM for South Korea. All of its plans that claim “Unlimited” in the name provide a daily data allowance—typically 3GB/day for the South Korea line or 1GB/day for broader Asia plans—and after that limit the speed to 1000kbps.

Customers looking for a higher data allowance can choose from fixed‑data plans. For instance, the South Korea · 50 GB · 30 days plan provides a 50 GB high‑speed allocation for 30 days at $37.00 USD, and the South Korea · 30 GB · 30 days plan offers 30 GB for $23.50 USD. These fixed‑data options can be more cost effective for typical travelers than the capped daily solutions.

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.
