EtravelSIM eSIM Data Plans for South Korea

EtravelSIM does not offer a true unlimited data eSIM for South Korea. The plans that carry the “Unlimited” name give a daily allowance of 4GB and, after that limit is reached, the connection speed drops to 128kbps. Because the high‑speed data is capped each day, the plans are not unlimited in the sense of continuous high‑speed access.

Instead, travelers can choose fixed‑data options that provide larger allowances without throttling. For example, a 50GB plan for 30 days costs $49.99 USD, and a 25GB plan for 30 days costs $27.50 USD. These fixed plans can be more cost‑effective for users who need steady high‑speed data throughout their stay.

EtravelSIM does not provide South Korea eSIM plans that include a phone number or SMS capability. All eSIM offerings for South Korea are data‑only; they lack inbound or outbound voice and text services. Travelers who require voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not depend on a local phone number.

EtravelSIM lists a total of 19 data plans that cover South Korea. Ten of those are single‑country packages, providing data exclusively for South Korea, while nine are multi‑country packages that include South Korea as part of a broader regional coverage.

The available plans span a price range from around $4.50 to $109.99 and a data cap between 1 GB and 50 GB, with validity periods from 5 to 365 days. Within the South Korean assortment, a handful of packages are sold with a daily data allowance (4 plans), while the majority are fixed‑data packages (15 plans). This means customers can choose either a plan that grants a set amount of data for the entire validity period or a plan that allows a specific daily data limit—often useful for short trips.
