AlpineSIM eSIM Data Plans for South Korea

AlpineSIM does not provide a truly unlimited data eSIM for South Korea. All of the plans marketed with the word “Unlimited” actually have a fixed data cap, such as 500 MB per day, 1 GB per day, or 2 GB per day, and after the allocation the speed is usually throttled.
If a larger, continuous data allowance is preferred, AlpineSIM offers fixed‑data plans for South Korea, such as the 20 GB and 50 GB packages, which can be more cost‑effective for travelers who need a lot of data without the daily limits of the “Unlimited” options.

AlpineSIM does not offer an eSIM plan for South Korea that includes a phone number or SMS capability. The provider’s South Korea offerings are limited to data‑only plans.

Travelers who need to make voice calls or send text messages can use popular VoIP applications—such as WhatsApp, Telegram, or iMessage—over the data connection provided by the eSIM.

AlpineSIM provides a mix of single‑country and multi‑country data plans that cover South Korea. In total, there are nine single‑country plans and 136 multi‑country plans that include South Korea. The available plans span a price range of approximately $0.46 to $268.79 and a data cap range of 100 MB to 50 GB. Among them, 84 plans feature a daily data cap and 61 offer a fixed data amount; some plans allow tethering.
