Comet SIM eSIM Data Plans for South Korea

Comet SIM does not offer an unlimited data eSIM for South Korea. The provider’s plans for the country are fixed data bundles that must be used within a set validity period. Two common options are the 20 GB bundle valid for 30 days and the 10 GB bundle also valid for 30 days. Choosing a fixed‑data plan can be more cost‑effective unless a traveler expects to consume an extremely large amount of data.

Comet SIM does not provide a South Korea eSIM that includes a local phone number or SMS capability. The provider offers only data‑only plans for South Korea. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in South Korea before purchasing, as some destinations may block or restrict certain apps.

Comet SIM offers five single‑country plans and ten multi‑country plans that include South Korea. The available plans range in price from about $3.90 to $119.90 and provide data caps between 1 GB and 20 GB, with validity periods from 7 to 30 days. The single‑country options give you a dedicated data allowance for South Korea alone, while the multi‑country plans bundle data that can be used across several destinations, allowing travelers to switch between countries without purchasing a new plan.
