Ovosim eSIM Data Plans for South Korea

Ovosim does not provide a true unlimited data eSIM for South Korea. All plans that carry the word “Unlimited” in their name are actually capped at 2‑5 GB per day for 5‑10 days; after the quota is reached the speed is reduced. Travelers who need unrestricted high‑speed data can choose one of Ovosim’s fixed‑data plans, such as the 50GB 30Days plan for $45.68 USD or the 20GB 30Days plan for $27.40 USD. Selecting a fixed‑data option may be more cost‑effective for many users, especially those who are not extremely heavy data consumers.

Ovosim does not provide a South Korean eSIM that includes a local phone number or SMS capability. Only data‑only eSIMs are offered for South Korea, so travelers can use the internet for browsing and can rely on VoIP applications such as WhatsApp, Telegram, and iMessage for voice and text communication over the data connection.

Ovosim offers 39 single‑country eSIM options that cover South Korea and an additional 52 multi‑country bundles that include the country. The plans range in price from about US$4.05 to US$115.92 and provide data caps from 1 GB up to 51 GB, with validity periods between 5 and 30 days. Some eSIMs come with a fixed data amount for the entire validity, while others allow a daily data cap, giving travelers the choice between a set total or a per‑day data allocation.
