SimBalkan eSIM Data Plans for South Korea

SimBalkan does not provide a truly unlimited high‑speed data eSIM for South Korea. All plans that carry “Unlimited” in the name give only 1 GB of data per day or a total of 1 GB for the validity period, which means the data is capped and the connection speed is reduced after the limit is reached.

For travelers who want more data, SimBalkan offers fixed‑data plans such as the 20 GB plan valid for 30 days at $11.39 USD, the 10 GB plan for 30 days at $6.79 USD, or the 5 GB plan for 30 days at $4.49 USD. These plans provide larger data allowances and may be more cost‑effective for users with heavier data needs.

SimBalkan does not provide any South Korea eSIM that includes a phone number or SMS functionality. The provider offers only data‑only plans for South Korea.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, use of these services can be restricted in some destinations, so it is advisable to confirm that the apps you intend to use are accessible in South Korea before purchasing a plan.

SimBalkan provides a range of data offerings for travelers in South Korea. Among the options, there are 10 single‑country plans that give coverage exclusively within South Korea. Additionally, the provider offers 5 multi‑country plans that include South Korea as part of a broader regional coverage. The plans are structured in two main ways: some provide a fixed data amount for the entire validity period (11 such plans), while others cap the data on a daily basis (4 daily cap plans). Overall, the available packages span a price range from roughly $3.31 to $51.28 USD, with data caps from 1 GB up to 20 GB and validity periods between 1 and 30 days.
