BNESIM eSIM Data Plans for South Korea

BNESIM does not provide a truly unlimited data eSIM for South Korea. All of its South Korean offerings are fixed‑data plans, even when the plan name includes the word “Unlimited.” For example, BNESIM sells a 200GB plan valid for 10 days, a 100GB plan valid for 30 days or with unlimited validity, and a 50GB plan also available for 30 days or unlimited validity. These plans provide high‑speed data up to the specified cap; after the cap is reached, the speed is typically reduced, although no specific reduced speed is listed in the data. Choosing a fixed data plan can be more cost‑effective unless a traveler is an extremely heavy data consumer who would need more than the largest available allowance.

BNESIM does not provide an eSIM for South Korea that includes a local phone number or SMS capability. All eSIM plans from BNESIM available in South Korea are data‑only, with no voice or text services built into the plan.

Travelers who need to make calls or send messages can use internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection supplied by the BNESIM eSIM.

BNESIM offers 21 single‑country data plans that cover South Korea and 40 multi‑country plans that include South Korea. The available plans range in price from roughly $2.08 to $262.36 and provide data caps from 1 GB up to 200 GB. Most of them allow tethering, giving users the ability to share data with several devices. The plans are either fixed‑data packages—where the total data amount remains constant for the plan’s validity—or daily‑cap options that limit usage each day; the specific type can be verified on BNESIM’s official site.
