eSIMCard eSIM Data Plans for South Korea

eSIMCard does not provide a truly unlimited data eSIM for South Korea. The plans that carry the word “Unlimited” in their name actually have a fixed data allowance of 1GB/day or 2GB/day, and once that amount is used the speed is reduced to 512kbps or 2000kbps. Therefore, these plans are not unlimited in the sense of providing high‑speed data without limits.

If a traveler needs a larger, fixed data allowance, eSIMCard offers several high‑capacity plans. For example, a 100GB eSIM Data plan for 180 days for South Korea costs $65.41 USD, and a 100GB eSIM Data plan for 30 days for Asia costs $109.25 USD. These fixed data plans give a substantial amount of high‑speed data that does not have a daily cap, though the data must be used within the validity period. Choosing a fixed data plan can be more cost‑effective unless the user is an extremely heavy data consumer.

eSIMCard does not provide South Korea eSIM plans that include a phone number or SMS capability. The provider’s South Korea offerings are data‑only plans with no telephony services.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but availability of these services in South Korea can be affected by local restrictions. It is advisable to confirm that the specific apps you rely on are accessible in South Korea before purchasing a data‑only eSIM from eSIMCard.

eSIMCard provides 11 single‑country plans and 100 multi‑country plans for South Korea. The plans cover a price range from $1.90 to $395.07 and data caps between 1 GB and 100 GB. Some plans use a fixed data amount, while others offer a daily data cap, giving travelers flexibility depending on their usage patterns.
