Sim Local eSIM Data Plans for South Korea

Sim Local does not provide a truly unlimited data eSIM for South Korea. The plans that carry “Unlimited” in their names actually offer a daily data allowance of 5GB/day or 10GB/day for 7 or 15 days, after which the speed is reduced. Because the data cap is a hard limit, the plan is not unlimited.

Travelers who need more data can choose from Sim Local’s fixed data plans. For example, a 20GB plan is available for 30 days, and larger bundles such as 50GB or 100GB are sold for 31 days. These fixed‑data options give a set amount of high‑speed data and can be more cost‑effective for most users unless they require very heavy data usage.

Sim Local does not offer eSIM plans that provide a phone number or SMS capability for South Korea. Travelers using Sim Local’s South Korean eSIM will receive only a data plan.

For voice and messaging, users can rely on internet‑based services such as WhatsApp, Telegram, or iMessage. Because some destinations can restrict access to certain VoIP services, it is advisable to verify that the apps you need are functional in South Korea before purchasing a plan.

Sim Local provides a total of 19 data plans that cover South Korea, split into 9 single‑country plans and 10 multi‑country plans. The plans range from 500 MB to 100 GB of data and are priced between $4.00 and $93.50. Some options are structured with daily data caps—typically lasting one day—while others use fixed data caps that remain available for the plan’s validity period. This mix allows travelers to choose between short‑term, low‑data usage or longer‑duration, higher data needs.
