eSIM4Travel eSIM Data Plans for South Korea

eSIM4Travel does not provide a truly unlimited data eSIM for South Korea. The plans that carry “Unlimited” in their name offer a fixed allowance of 3GB each day; after the daily limit is reached, the speed is throttled to 1000 kbps, so data usage is still capped.

Instead, eSIM4Travel offers fixed data plans that give larger high‑speed allowances. Examples include a 50 GB data bundle valid for 30 days and a 20 GB bundle also valid for 30 days, both delivered on 5G networks in South Korea. These fixed‑data options are available if you need more data than the daily‑limited “Unlimited” plans allow.

eSIM4Travel does not currently offer a South Korea eSIM plan that includes a phone number or SMS capability. The only available South Korea plans from eSIM4Travel are data‑only options.

Travelers who need voice or text calls can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific VoIP apps, so it is advisable to verify that the apps relied upon are accessible in South Korea before purchasing a plan.

eSIM4Travel lists 21 single‑country data plans covering South Korea and 12 multi‑country plans that include South Korea. Prices span from $0.69 to $77.36 USD, with data caps ranging from 1 GB to 50 GB. Plans are offered in two main styles: fixed‑data‑cap packages, where the total amount of data remains the same for the entire validity period, and daily‑data‑cap packages, which grant a set amount of data each day.
