Airalo eSIM Data Plans for South Korea

Airalo does not provide a truly unlimited high‑speed data eSIM for South Korea. Plans that carry the name “Unlimited, ” such as the 짱 Jjang and LG U⁺ options, allow 3 GB per day; once that limit is reached the speed is throttled to 1000 kbps or 5000 kbps. These plans are therefore capped in the same way that most fixed‑data plans are.

If a travel eSIM with a higher total data allowance is preferred, Airalo offers fixed‑data options that are billed for a set number of days. Examples include the Asialink 100 GB plan valid for 180 days that uses 5G coverage across South Korea and 17 additional countries, the Asialink 50 GB plan for 90 days, and the 짱 Jjang 50 GB plan for 30 days. Choosing a fixed‑data plan can be more cost effective than the capped “Unlimited” type, especially for heavy data users who need a predictable amount of high‑speed data.

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 provides 20 single‑country plans that cover South Korea and an additional 20 multi‑country plans that also include South Korea. The plans come in both fixed‑data and daily‑cap variants, allowing travelers to choose either a set amount of data for a specific duration or a daily limit. Prices generally range from roughly $4 to $185, while data caps vary from 1 GB up to 100 GB across the available options.
