merdata eSIM Data Plans for South Korea

Merdata does not provide an unlimited data eSIM option for South Korea. All plans available through merdata for this country include a fixed data allowance and a validity period, meaning the traveler must use the data within a set number of days.

Merdata’s fixed data plans for South Korea include, for example, a 50 GB bundle that is valid for 30 days and costs $31.67 USD, and a 20 GB bundle that is also valid for 30 days and costs $21.08 USD. These plans offer large data allowances, but they have a hard validity limit, which can be more cost‑effective for most travelers unless they are extremely heavy data users.

merdata does not provide a South Korea eSIM plan that includes a phone number or SMS capability. The South Korea eSIMs offered by merdata are data‑only.

Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and text communication. However, access to these services can vary by destination and is not guaranteed; travelers should verify that the apps they rely on will work in South Korea before purchasing a data‑only plan from merdata.

Merdata lists 13 single‑country plans and 64 multi‑country plans for South Korea. The single‑country offerings allow travelers to remain in one country for a set period with a fixed data allowance, while the multi‑country plans enable access across several regions for a validity that can range from one day up to a full year. Across both categories, plans are priced from roughly $1.48 to $105.81 and data caps range from 500 MB to 50 GB.
