Airalo eSIM Data Plans for South Korea

Airalo does not provide a true unlimited data eSIM for South Korea. All plans marketed as “Unlimited” give a maximum of 3 GB per day; after that daily limit is reached the connection speed is throttled to 1000kbps (or 5000kbps for the LG U⁺ option).

Travelers who need an unfettered data experience can instead choose one of Airalo’s fixed‑data plans. For example, the Asialink 100 GB plan delivers 100 GB of high‑speed 5G data over 180 days for $89.00 USD, and the Asialink 50 GB plan offers 50 GB for 30 or 90 days, priced between $59.00 and $69.00 USD. These fixed‑data options may provide a better cost–value balance for users who anticipate heavy data usage in South Korea.

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.
