iRoamly eSIM Data Plans for South Korea

iRoamly does not provide a true unlimited data eSIM for South Korea. All plans listed under the iRoamly catalog for South Korea give a fixed high‑speed data allowance of 500GB. Examples from the dataset include a 1‑day 500GB plan priced at $2.00 USD and a 30‑day 500GB plan priced at $58.00 USD. These plans are labelled “Unlimited” in the product name, but the name does not reflect an uncapped data amount. Because a single data cap is specified, after the 500GB quota is reached the speed would typically be reduced, although the exact throttled speed is not disclosed in the available information.

If an unlimited data option is required, the fixed‑data plans remain the only available alternative. While choosing a fixed data plan can be more cost effective for travelers who consume large amounts of data, it may not suit extremely heavy data users who need truly unlimited data without any caps.

iRoamly does not provide a South Korea eSIM that includes a local phone number or SMS capability. The provider’s South Korea plans are data‑only, enabling use of applications such as WhatsApp, Telegram, and iMessage for voice and messaging over the data connection.

iRoamly offers 73 single‑country and 48 multi‑country plans for South Korea. Most of the plans are fixed‑data options, but a smaller subset has daily data caps. Prices vary from free to about $257 USD, and data caps range from 500 MB up to 500 GB, with validity periods that can last from one day to a full year. Many plans include tethering, and some are limited to new users or offer reduced speed during peak times.
