TooSim eSIM Data Plans for South Korea

TooSim does not provide any unlimited data eSIM plan for South Korea. The available options are fixed data plans with specific data caps and a validity of 30 days, such as the 10GB, 20GB, and 50GB bundles. For travelers who need a large amount of data, the 50GB 30‑day plan or the 20GB 30‑day plan offer substantial capacity, and choosing a fixed data plan can be more cost‑effective unless extremely heavy data usage is expected.

TooSim does not provide eSIM plans for South Korea that include a phone number or SMS capability. Travelers receiving an eSIM from TooSim for South Korea will have access only to data usage.

Because the plan offers no native voice or SMS service, travelers can still communicate through internet‑based applications such as WhatsApp, Telegram, or iMessage, provided those services are not blocked in South Korea. It is advisable to verify that the specific VoIP apps you intend to use are available and functional in South Korea before purchasing the data‑only plan.

TooSim provides seven single‑country data packages for South Korea and seven multi‑country packages that include South Korea. The offerings run from about $7.99 to $138.99 and include data caps between 1 GB and 50 GB; a number of the plans allow tethering.
