merdata eSIM Data Plans for South Korea

Merdata does not offer an unlimited data eSIM plan for South Korea. Travelers who need a large amount of data can choose from the fixed options that the provider lists, such as the eSIM South Korea 50 GB 30 days plan priced at $31.10 USD and the eSIM South Korea 20 GB 30 days plan at $20.70 USD. These plans provide a clear data allowance and an explicit validity period, which can be more cost‑effective for most users unless a very heavy data consumption is anticipated.

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 provides 14 single‑country data plans and 50 multi‑country plans for South Korea. The plans are mainly fixed‑data‑amount offerings, ranging in price from about $1.43 to $102.14 and covering data from 500 MB up to 50 GB. Some of the plans allow reduced‑speed options, with speed limits of 512 kbps, 1000 kbps, 384 kbps, or 128 kbps.
