Simbye eSIM Data Plans for South Korea

Simbye does not provide a truly unlimited data eSIM for South Korea. All Simbye packages enable high‑speed data, but the South Korea Unlimited plans cap usage at 2GB per day; once this limit is reached the speed is throttled to 1000 kbps. Because of this daily cap the plans are not unlimited.

Travelers who need more data can select from Simbye’s fixed‑data offerings. For example, the 20GB 30‑day plan is available for $19.99 and the 5GB 30‑day plan is available for $9.99, both delivered on 5G across South Korea. Fixed‑data plans can be more cost‑effective for most users unless extremely heavy data consumption is required.

Simbye does not provide South Korea eSIM plans that include a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from Simbye for use in South Korea. If callers need to make or receive voice or text communications, they may use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict access to certain VoIP services, so travelers should verify that the apps they rely on are available in South Korea before purchasing a plan.

Simbye offers eleven data‑only eSIM plans that include South Korea. Six of those plans are single‑country, covering only South Korea, while five are multi‑country plans that allow use in additional destinations. The available packages range in price from $3 to $55, provide data caps between 1 GB and 20 GB, and have validity periods from 7 to 90 days. Some plans give a fixed data allowance, while others apply a daily data cap.
