Lotso Travel eSIM Data Plans for South Korea

Lotso Travel does not sell a data plan that provides unlimited high‑speed data for South Korea. All plans listed under the “Unlimited” label actually offer a capped allowance of 3GB/day, 2GB/day, or 5GB/day, and after the cap is reached the speed is throttled to 1000kbps.

If unlimited data is not a requirement, Lotso Travel offers fixed‑data options such as the 20GB plan for 5 days (priced at $22.00 USD) or the 20GB plan for 10 days (priced at $24.00 USD). These higher‑capacity plans can be more cost effective than the capped “Unlimited” packages if you need a larger amount of data for a longer stay.

Lotso Travel does not provide eSIM offers that include a phone number or SMS service for South Korea. Only data‑only plans are available from this provider in that country.

Travelers who require voice or text can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which allow calls and messaging without a local phone number or SMS capability.

Lotso Travel offers 32 single‑country plans and 32 multi‑country plans that include South Korea. The single‑country plans range from $5.00 to $104.00 and provide data caps between 1 GB and 20 GB, with validity periods from 5 to 30 days. These plans are a mix of fixed‑data options—providing a set amount of data for the entire validity—and daily data‑cap options, which allocate a specific amount of data per day. The multi‑country plans offer a similar price and data range while allowing coverage in several destinations, including South Korea. This combination gives travelers flexibility whether they need a focused stay in South Korea or a roaming solution across multiple countries.
