Lumbus eSIM Data Plans for South Korea

Lumbus does not provide a true unlimited data eSIM for South Korea. The plans that use the word “Unlimited” in their names actually give a fixed amount of high‑speed data: each day the user receives 3 GB at 5G speeds, and once that daily allowance is used the connection slows to 1000 kbps. All other Lumbus plans for South Korea have a hard data cap, such as the 50 GB plan for 30 days or the 20 GB plan for 30 days, which offer larger daily allowances without the post‑cap speed reduction. These fixed data plans are typically more cost‑effective unless a traveler requires very heavy data usage.

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 11 single‑country plans and 43 multi‑country plans that include South Korea. The available plans span a price range of about $2.99 to $140.99 and a data cap range from 1 GB up to 50 GB. Some plans are capped by a fixed data amount, while others impose a daily data cap, allowing users to choose between a single bulk data allotment or a shorter daily allowance.
