Ohayu eSIM Data Plans for South Korea

Ohayu does not provide any unlimited data eSIM plans for South Korea.
Travelers who need a larger data allowance can choose from fixed plans such as the 50GB 30 days plan priced at $76.79 USD or the 25GB Monthly plan costing $49.49 USD. These fixed plans offer 5G coverage within South Korea (and, in the case of the 25GB monthly plan, additional coverage in 105 other countries). Choosing a fixed data plan can be more cost‑effective for most users unless extremely heavy data consumption is anticipated.

Ohayu does not offer a South Korea eSIM that includes a phone number or SMS capability. The provider only sells data‑only eSIM plans for travel in South Korea and currently does not provide telephony services in that destination.

Because a phone number and SMS are not available, travelers who need to communicate while abroad can rely on popular VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over a data connection and allow voice calls and messaging without a traditional phone number.

Ohayu provides a total of five single‑country data plans and four multi‑country data plans for South Korea. The available plans range in price from $9.49 to $76.79 and in data caps from 2GB to 50GB, with validity periods of 15 to 30 days. Single‑country plans allow usage only within South Korea, while multi‑country plans grant access across other covered regions; several of the plans also permit tethering.
