Airalo eSIM Data Plans for South Korea

Airalo does not provide a true unlimited data eSIM for South Korea in which high‑speed data is available without restrictions. The available “Unlimited” plans are limited to 3 GB per day, and once that daily cap is reached the speed drops to 1000 kbps (or 5000 kbps for the LG U⁺ option). For travelers who need more data without the daily limit, Airalo offers fixed‑data plans such as the Asialink‑100 GB plan valid for 180 days at $89.00 USD and the ‘짱 Jjang‑50 GB plan valid for 30 days at $49.00 USD. These fixed‑data options can be more cost‑effective for heavy data users.

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.
