Airalo eSIM Data Plans for South Korea

Airalo does not provide a truly unlimited data eSIM for South Korea. Plans that carry the name “Unlimited” actually offer a 3GB/day data cap and reduce speed to 1000kbps after that limit is reached; the LG U⁺ “Unlimited” variant reduces speed to 5000kbps once the 3GB/day cap is used.

Travelers can instead choose from fixed‑data plans that give much larger allowances and retain full speed. For example, Asialink offers a 100GB plan valid for 180 days at $89.00, while 짱 Jjang provides a 50GB plan for 30 days priced at $49.00. Other substantial options include Asialink’s 50GB for 90 days at $69.00 and the 20GB plan for 15 days at $31.00. Fixed‑data offers can be more cost‑effective for users who need more data than the 3GB/day capped “Unlimited” plans provide.

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 total of 54 data plans that cover South Korea: 20 single‑country plans specifically for the country and 34 multi‑country plans that include South Korea among other destinations. The plans span a price range from $4.00 to $89.00, provide data capacities between 1 GB and 100 GB, and are valid for 3 to 365 days. Customers can choose from plans with a fixed data allotment—generally a set amount of data you can use during the validity period—or from daily‑data‑cap plans, which reset your data allowance each day during the plan’s active period.
