ETravelSim eSIM Data Plans for South Korea

ETravelSim does not provide a truly unlimited high‑speed data eSIM for South Korea. Plans labeled “Unlimited” actually allow 4 GB of data per day and then reduce speed to 128 kbps once the daily allotment is reached, so the data are not unbounded.

Instead, ETravelSim offers fixed‑data plans that can be more cost‑effective for regular travelers. For example, the “South Korea eSIM 50 GB – 30 days” plan gives 50 GB of high‑speed data for 30 days at $49.99 USD, and the “South Korea eSIM 25 GB – 30 days” plan provides 25 GB for $27.50 USD. These fixed‑data options are the primary choices for travelers visiting South Korea.

No, ETravelSim does not offer a South Korea eSIM that includes a phone number or the ability to send SMS. All eSIM plans for South Korea provided by ETravelSim are data‑only. Travelers can still stay connected using popular VoIP services such as WhatsApp, Telegram, and iMessage, which work over a data connection and allow calls and messaging without requiring a local phone number or SMS capability.

ETravelSim offers 10 single‑country plans that cover South Korea exclusively, and 9 multi‑country plans that include South Korea as part of a broader regional package. Prices range from about $4.50 to $109.99, while data caps span from 1 GB to 50 GB. Some plans provide a fixed amount of data for the entire validity period, whereas others allow a daily data cap, giving users flexibility based on how they wish to control their usage during the trip.
