eSIM4Travel eSIM Data Plans for South Korea

eSIM4Travel does not provide a truly unlimited high‑speed data plan for South Korea. The plans that include “Unlimited” in their names give a fixed allowance of 3GB per day, and after that limit is reached the speed is reduced to 1024 kbps.
For travelers who need more data, fixed‑data options are available. One example is the 50GB/30 days plan at $43.24, which offers 5G coverage in South Korea, while the 90GB/365 days plan costs $200 and covers South Korea plus 69 other countries. These alternatives may be more cost‑effective if you require data beyond the daily 3GB cap.

eSIM4Travel does not provide a South Korea eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are available.

You can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage with the data plan to make calls and send messages over the Internet.

eSIM4Travel lists 15 single‑country plans and 16 multi‑country plans that cover South Korea. The single‑country options give you a dedicated local network, while the multi‑country packages allow usage across several destinations, including Seoul, Busan and other Korean cities.

The available plans span a price range of about $1.29 to $200 and a data cap range from 1 GB up to 90 GB. Some plans are structured with an overall fixed data amount, providing a set total that can be used over the validity period, whereas others use a daily data cap, limiting the amount you can use for each day of the plan’s duration. Both structures are present—eight plans employ daily caps and 23 use fixed caps—offering flexibility for short‑term travelers or longer stays.
