Airalo eSIM Data Plans for South Korea

Airalo does not provide a truly unlimited high‑speed data eSIM for South Korea. All plans that carry “Unlimited” in the name, such as LG U⁺ – Unlimited, actually limit usage to 3 GB per day and throttle speed to 5000 kbps once the daily quota is reached. Travelers who need more data without this cap can choose from high‑allowance fixed plans. For example, Asialink offers a 100 GB plan valid for 180 days and a 50 GB plan valid for 90 days, both providing 5G coverage in South Korea and a larger country footprint. These fixed‑data options may be more cost‑effective for heavy data users compared to the daily‑cap unlimited alternative.

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 a variety of data plans for travelers to South Korea. Currently, there are 8 single-coverage plans specifically for South Korea, and an additional 20 plans that include South Korea as part of a wider regional or global coverage area. These plans range in price from approximately $4.50 to $185.00 and offer data allowances from 1GB up to 100GB. Some plans provide a fixed data amount, while others offer a daily data cap for usage.
