Sim Local eSIM Data Plans for South Korea

Sim Local does not supply a truly unlimited data eSIM for South Korea. The plans labeled “South Korea Unlimited Data” actually provide a capped high‑speed allowance of 5 GB per day or 10 GB per day; once the daily limit is hit the connection speed is reduced. For a more predictable budget, Sim Local offers fixed‑data alternatives such as 20 GB for 30 days or 100 GB for 31 days, which may be more cost‑effective unless one is an extremely heavy data consumer.

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.
