Travelsim Asia eSIM Data Plans for South Korea

Travelsim Asia does not currently provide an unlimited data eSIM plan for South Korea. All of the South Korea‑specific offerings are fixed‑data plans. For example, a 50 GB plan is available for 90 days at $130.99 USD, a 20 GB plan for 30 days at $47.99 USD, and a 10 GB plan for 30 days at $17.99 USD.

Choosing a fixed data plan can be more cost effective for most travelers, while an extremely heavy data user may need to consider a higher‑cap or multi‑country package to meet their needs.

Travelsim Asia does not provide a South Korea eSIM plan that includes a phone number or SMS capability. All of its South Korea offerings are data‑only and do not support inbound or outbound calls or text messages.

Travelers who need to stay connected can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make voice calls and send messages, as these services do not require a local phone number.

Travelsim Asia provides five single‑country data plans and four multi‑country plans for travelers heading to South Korea. The available offers range from about $4.99 to $130.99 and include data caps between 1 GB and 50 GB, with validity periods spanning 7 to 90 days. Single‑coverage plans focus solely on South Korea, while multi‑coverage plans bundle South Korea with other destinations, often allowing tethering on selected packages.
