AlpineSIM does not offer a truly unlimited data eSIM for South Korea. All plans marketed with the word “Unlimited” actually have a daily data cap, such as 500 MB, 1 GB, or 2 GB, and the plans do not provide an unrestricted high‑speed data allowance. Because of the caps, the speed can be reduced once the limit is reached, but the dataset does not specify the throttled rate.
Instead, AlpineSIM provides fixed‑data plans for South Korea. For example, a 50 GB plan for 30 days costs $23.59 USD, and a 20 GB plan for 30 days costs $11.38 USD. These fixed‑data options give travelers a larger and predictable data budget and can be more cost‑effective for moderate to high usage compared with the capped “Unlimited” options.
AlpineSIM does not provide an eSIM for South Korea that includes a phone number or SMS capability. The provider only offers data‑only plans for the country, so travelers must rely on internet access for any voice or text communication.
Users can still make calls and send messages through VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these apps are accessible in South Korea before purchasing a plan.
AlpineSIM provides both single‑country and multi‑country data plans for South Korea, with a total of 57 single‑coverage plans and 156 multiple‑coverage plans that include the destination in their itineraries. The plans span a price range from $0.43 to $274.89 and offer data caps between 100 MB and 50 GB. Travelers can choose between daily data cap options—140 plans that reset each day—and fixed data cap plans—73 that provide a set data allowance for the entire validity period. This variety allows travelers to select a plan that matches their usage needs and travel duration.
