Beware: 1) No call/text available in South Korea. 2) Routed via HK so not the best service due to latency, but the same as most competitors in SK for eSIM. 3) Weird discrepancy on their website about price in USD vs charged amount ($1.00 USD more is charged than shown online). How do I know? I bought 3 eSIMs from Giga.Tel in South Korea, and over 10 from eSIM competitors. So far they are still the cheapest for the same 30GB and quality of service. Plus you can checkout with American Express in case of a dispute (MobiMatter does not allow Amex)
Giga.Tel’s plans that bear the “Unlimited” label actually limit high‑speed data to 1GB per day. After the 1GB daily cap is reached, the speed falls to 512 kbps, as seen in the Global Unlimited 5‑Day, 7‑Day, 10‑Day and 15‑Day plans available for South Korea. While these plans offer a large total amount of data over several days, they are not truly unlimited for high‑speed use.
If a traveler needs continuous high‑speed data without speed throttling, Giga.Tel’s fixed‑data eSIMs can be more cost‑effective. For South Korea, options include the South Korea (Dual Networks) 50GB 30‑Day eSIM, the Vietnam Plus 60GB 60‑Day eSIM that covers South Korea, and the China Korea Japan 60GB 90‑Day eSIM, each providing a generous data allowance with no daily limit on speed.
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.
For South Korea, Giga.Tel lists 22 single‑country plans that provide a fixed data amount for a set validity period. In addition, 43 multi‑country plans include South Korea as part of a broader coverage zone. These options span a price range of about $4.99 to $195.99 and data allowances from 1 GB up to 90 GB, with both fixed‑data and daily‑data‑cap structures available.
