Travelsim Asia eSIM Data Plans for South Korea

Travelsim Asia 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. For example, a 20 GB plan is available for 30 days at $23.99 USD, and a 10 GB plan is available for 30 days at $16.99 USD. Choosing a fixed data plan can be more cost‑effective unless a traveler is an extremely heavy data consumer.

Travelsim Asia 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 can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages, but they should confirm that the apps they rely on are accessible in South Korea before purchasing the plan.

Travelsim Asia provides five single‑country plans that cover South Korea, and an additional six multi‑country plans that include South Korea among other destinations. The plans range in price from USD 2.99 to USD 80.00 and offer data caps between 1 GB and 20 GB. Validity periods vary from 7 to 30 days. Some of the plans allow tethering to share the data with other devices.
