Airalo eSIM Data Plans for South Korea

Airalo does not offer a truly unlimited high‑speed data eSIM for South Korea. The plans that carry “Unlimited” in their names actually provide 3GB of high‑speed data each day and, once this daily quota is reached, the speed is throttled to 1000kbps (or 5000kbps for some LG U⁺ offerings). After the limit, data can still be used but at a reduced speed, so the plans are not unlimited in the sense of providing unlimited high‑speed connectivity without any cap.

Instead, Airalo sells fixed‑data eSIMs that can be more cost effective for travelers needing larger data allowances. For example, the Asialink 100 GB plan provides 100 GB of high‑speed data for 180 days at $89.00, and the Asialink 50 GB plan offers 50 GB for 30 days at $59.00. These fixed plans allow users to buy a specific amount of data and use it over a longer period, avoiding the daily cap and speed reduction that apply to the “Unlimited” name plans.

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 18 single‑country plans and 32 multi‑country plans for South Korea. The catalogue includes both fixed data‑cap options, which provide a set amount of data for non‑renewable periods ranging from 1 GB to 100 GB, and daily‑cap plans that refresh each day, giving travelers more flexibility with shorter usage windows. Prices across the collection start at roughly 4 USD and can be as high as 89 USD, giving users a broad spectrum of data volumes and cost choices.
