AlpineSIM eSIM Data Plans for South Korea

AlpineSIM does not offer a truly unlimited data eSIM for South Korea. All of the plans labelled “Unlimited” in the catalogue provide a fixed daily allowance—typically 500 MB or 1 GB per day—after which the data speed is reduced; they do not allow high‑speed data without limits more than that daily quota.

If an unlimited‑plan type is required, AlpineSIM provides large fixed‑data packages instead. For example, a 50 GB eSIM is valid for 30 days, and a 20 GB eSIM is available for the same validity period. These fixed‑data plans can be more cost‑effective for travelers who expect to use a substantial amount of data during their stay in South Korea.

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.
