BlueSky eSIM eSIM Data Plans for South Korea

BlueSky eSIM does not provide a truly unlimited data eSIM for South Korea. The plans that carry “Unlimited” in their name actually offer a fixed daily allowance of 3GB; after that amount the speed is reduced to 1 Mbps.

Travelers who need more data can choose from BlueSky eSIM’s fixed data plans, such as the 100GB plan valid for 180 days or the 50GB plans valid for 7, 15, 30, or 90 days. These plans give a larger high‑speed data allowance and may be more cost‑effective for users who consume a lot of data.

BlueSky eSIM does not provide plans that include a local phone number or SMS capability for South Korea. Travelers who need a phone number and SMS will find that BlueSky offers only data‑only eSIM options for this destination. However, common VoIP services such as WhatsApp, Telegram, and iMessage can usually be used over the data connection for voice and messaging, though some destinations may block or restrict certain apps and users should verify access before purchasing.

BlueSky eSIM offers 11 single‑country plans and 29 multi‑country plans for South Korea, giving travelers a total of 40 different options. The plans span a price range from $1.52 to $100.15 USD and data caps between 200 MB and 100 GB. Among these, some plans use a daily data cap (10 plans) that limits usage each day, while others employ a fixed data cap (30 plans) that adds up over the entire validity period.
