Simbye eSIM Data Plans for South Korea

Simbye does not provide a truly unlimited high‑speed data eSIM for South Korea. The plans that carry the name “Unlimited” actually supply 2GB of high‑speed data each day, and once that daily limit is reached the connection drops to a reduced speed of 1000 kbps.

Instead, Simbye offers fixed data plans that can be a better value for most travelers. For example, a 20 GB plan for 30 days or a 10 GB plan for 30 days gives full‑speed data for the entire validity period without throttling.

Simbye does not offer a South Korea eSIM that includes a local phone number or SMS capability. The provider’s South Korea offering is data‑only. Travelers can still make calls and send messages by using popular VoIP apps such as WhatsApp, Telegram, and iMessage, which operate over the data connection.

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.
