Ovosim eSIM Data Plans for South Korea

Ovosim does not provide a true unlimited data eSIM for South Korea. Existing plans labeled “Unlimited” actually offer a daily data cap of 3GB/day, 5GB/day, or 2GB/day, after which speed is altered.

Travelers who need larger data volumes can choose fixed‑data options. For example, a 50GB plan is available for 30 days, and a 20GB plan is also sold for the same period. These fixed plans give more data for the price and may be more cost effective for heavy users.

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.
