Zwitchy eSIM Data Plans for South Korea

Zwitchy does not provide a truly unlimited data eSIM for South Korea. The plans that carry “Unlimited” in their names give a daily allowance – for example, South Korea · Unlimited – 3 days provides 3GB per day and after the daily cap the speed drops to 1000 kbps. Thus, once the daily data limit is reached the connection is throttled.

For travelers who need larger amounts of high‑speed data without daily limits, Zwitchy offers fixed data plans. A 50 GB plan valid for 30 days costs $38.50 USD, while a 30 GB plan for the same validity costs $24.00 USD. These options give a set data allowance and keep 5G speeds throughout the period, which can be more cost‑effective for heavy data users.

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.
