Airalo eSIM Data Plans for South Korea

Airalo does not provide a truly unlimited data eSIM for South Korea; all of its plans with “Unlimited” in the name are limited to 3GB per day. After the 3GB daily threshold is reached, the connection is throttled to 1000 kbps, which reduces the speed of the remaining data. Examples include the “짱 Jjang - Unlimited” plan that offers 3GB/day for 30 days at $69.00 USD and the “Asialink - Unlimited” plan that provides 3GB/day for 30 days at $73.50 USD.

For travelers who need more data without daily caps, Airalo sells fixed‑data plans that can be more cost‑effective. These include the 100 GB plan for 180 days at $89.00 USD, several 50 GB plans ranging from 30 to 90 days for $49.00–$69.00 USD, and a 20 GB plan for 15 days at $29.00 USD. These alternatives allow consistent high‑speed data throughout the validity period without the daily limitation.

Airalo does not offer eSIM plans for South Korea that include a local phone number or SMS capability. Travelers can only purchase data‑only eSIMs for South Korea from Airalo. They can still use VoIP services such as WhatsApp, Telegram or iMessage over the data connection for calls and messaging, but no traditional voice or SMS service is provided.

Airalo offers 20 single‑country plans and 35 multi‑country plans for South Korea. The available plans break down into two main types: fixed data caps, where a set amount of data is allotted for the plan’s validity, and daily data cap options that reset each day during the validity period. Across all South Korean plans the price ranges from about $4 to $97, and the data caps vary from roughly 1 GB up to 100 GB.
