TooSim eSIM Data Plans for South Korea

TooSim does not provide an unlimited data eSIM for South Korea; all plans sold by TooSim for that country have a fixed data allowance. Travelers can choose from several high‑capacity options, such as a 50GB plan for 30 days priced at $132.99 USD or a 20GB plan for 30 days priced at $58.99 USD, both of which include tethering. These plans offer substantial data amounts, but they are not unlimited. Selecting a fixed data plan can be more cost effective for most users unless they are extremely heavy data consumers.

TooSim does not provide an eSIM for South Korea that includes a local phone number or SMS capability. The only eSIMs offered for South Korea by this provider are data‑only plans.

Because of the lack of telephony features, travelers rely on the data connection for voice and text. Popular VoIP apps such as WhatsApp, Telegram, and iMessage work over the data link and allow users to make calls and send messages without needing a local phone number or SMS service.

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.
