AlpineSIM eSIM Data Plans for South Korea

AlpineSIM does not provide a true unlimited‑data eSIM for South Korea. All of the plans that carry “Unlimited” in their name include a fixed data allowance, such as 500 MB per day, 1 GB per day or 2 GB per day, after which the speed may be reduced.

Travelers who need a large amount of high‑speed data can choose one of AlpineSIM’s fixed‑capacity plans. For example, a 50 GB plan valid for 30 days costs $25.21 USD, while a 20 GB plan for the same period costs $12.17 USD. These options are available specifically for South Korea and offer a straightforward alternative for users who are not extreme data consumers.

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 selection of plans that cover South Korea across both single‑country and multi‑country options. In the single‑country category there are nine distinct plans, while the multi‑country category lists 136 plans that include South Korea among their coverage. The available plans span a price range from $0.44 to $264.52, with data caps that vary from 100 MB up to 50 GB. Some of the plans operate with a daily data cap, meaning the data allowance resets each day, whereas others use a fixed data cap that remains constant for the entire validity period of the plan. This range of options allows travelers to choose a plan that best matches their data needs and budget.
