Lumbus eSIM Data Plans for South Korea

Lumbus does not provide a truly unlimited high‑speed data eSIM for South Korea. Their “South Korea Unlimited” plans supply only 3GB per day, after which the speed is reduced; this is a daily cap rather than an unlimited data allowance.

Travelers looking for larger data budgets can choose from the fixed‑data options listed by Lumbus. For example, the 50GB plan offers 30 days of validity, and the 20GB plan also gives 30 days. These alternatives provide a fixed amount of high‑speed data without the daily limit, which may be more cost‑effective for most users.

Lumbus does not offer an eSIM for South Korea that includes a phone number or SMS capability. Only data‑only eSIM plans are available from this provider. Travelers who need voice or text can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, availability of these apps can vary, so it is advisable to verify that the services you rely on are accessible in South Korea before purchasing.

Lumbus offers 12 single‑country plans that are valid only in South Korea, and 46 multi‑country plans that include South Korea in their coverage list. The plans are priced between $0.99 and $140.99, with data limits ranging from 500 MB to 50 GB and validity from 1 to 365 days. Some plans are sold as fixed‑data packages (54 in total) while a smaller subset uses a daily data cap (4 plans), giving customers flexibility in how they consume data. Tethering is permitted on the applicable plans.
