Sim Local eSIM Data Plans for South Korea

Sim Local does not provide a truly unlimited data eSIM for South Korea. All of the plans listed for South Korea are fixed data bundles, even those with “Unlimited” in the name. For example, the “South Korea Unlimited Data for 7 Days” offers 5 GB per day for a total of 35 GB over the 7‑day period, and the “South Korea Unlimited Pro Data for 7 Days” offers 10 GB per day for 70 GB total. These bundles are capped at the specified data amount; after the allowance is used the speed may be reduced.

If a traveller needs a large amount of high‑speed data, they can choose a fixed plan such as the 30‑day 20 GB bundle or the 31‑day 100 GB bundle. These options provide a set amount of data at a fixed price, and may be more cost‑effective than a pay‑as‑you‑go credit for most users.

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.
