Giga.Tel eSIM Data Plans for South Korea

Giga.Tel does not provide a truly unlimited high‑speed data eSIM plan for South Korea. Every plan that lists “Unlimited” in its name actually limits the data allowance to a fixed amount per day; after that limit the connection speed drops to 512kbps. For travelers in South Korea, Giga.Tel offers fixed‑data bundles instead, such as the 30GB plan valid for 7, 15, or 30 days and the 20GB plan valid for 7 or 15 days, both of which provide high‑speed data at a reduced speed of 128kbps once the allocation is used. These fixed data plans can be more cost‑effective for most users unless exceptionally heavy data usage is required.

Giga.Tel does not offer an eSIM plan for South Korea that includes a phone number or SMS capability. The only available eSIMs from Giga.Tel for South Korea provide data-only usage. Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which work without a local phone number or SMS service.

Giga.Tel offers 17 single‑country data plans for South Korea. In addition, the provider has 14 multi‑country plans that can be used in South Korea when travelers include it as one of their destinations. The available plans span a price range from $4.99 to $195.99 and a data cap range from 1 GB up to 30 GB, with validity periods from 1 to 30 days.
