Airalo eSIM Data Plans for South Korea

Airalo does not provide a truly unlimited data eSIM for South Korea. All of its plans for the country have a fixed data allowance, such as 3 GB per day for the “Unlimited”‑named bundles, after which the speed is reduced to 1 Mbps, or larger fixed bundles like 50 GB for 30 days or 100 GB for 180 days. Travelers who need more data can choose one of these fixed‑data plans, which may be more cost‑effective than a high‑usage plan that throttles after a daily limit.

Airalo’s eSIM plans for South Korea are data‑only; no local phone number or SMS service is provided. Travelers can still use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but they should confirm that these services are available in South Korea before purchasing, as some destinations may block or restrict certain apps.

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.
