ETravelSim eSIM Data Plans for South Korea

ETravelSim does not provide a genuinely unlimited data eSIM for South Korea.
The plans labeled “Unlimited” in their name deliver 4 GB per day; once that daily quota is reached the speed drops to 128kbps.
Internally, these plans still have a fixed data cap and are not continuous unlimited data at full speed.

Travelers who prefer a true unlimited experience will need to look elsewhere.
ETravelSim offers fixed‑data alternatives that may be more cost‑effective for most users, such as the 50 GB / 30 days plan priced at $49.99 USD or the 25 GB / 30 days plan priced at $27.50 USD.

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.
