SimBalkan eSIM Data Plans for South Korea

SimBalkan does not provide a truly unlimited data eSIM for South Korea. The plans with “Unlimited” in their name actually allow only 1 GB per day, so high‑speed data is capped on a daily basis. Travelers who need larger data allowances can choose from a range of fixed‑data plans, such as a 20 GB plan for 30 days priced at $11.26 USD or a 10 GB plan for 30 days at $6.71 USD. These fixed‑data plans give access to high‑speed data for the specified validity period and are often more cost‑effective unless one is an extremely heavy data consumer.

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 offers 10 single‑country eSIM plans for South Korea, with no multi‑country options available. The plans vary in price from about $3.30 to $30.60, provide data caps ranging from 1 GB to 20 GB, and are valid for between 1 and 30 days. Within these offerings, four plans feature a daily data cap, limiting usage on a day‑by‑day basis, while six plans provide a fixed total data amount that can be consumed anytime during the validity period.
