ChillaxSIM eSIM Data Plans for South Korea

ChillaxSIM does not provide a truly unlimited data eSIM for South Korea. All plans listed as “unlimited” actually give 1 GB per day; after that daily allowance is reached the speed is reduced to 5000 kbps. Travelers who want more data without the speed reduction can choose ChillaxSIM’s fixed‑data plans. For example, the 100 GB/day plans available for 1 day, 3 days, 5 days, 7 days, or 10 days give a large fixed allowance and do not have a reduced speed clause. These fixed plans may be a more cost‑effective choice unless a user is a very heavy data consumer who would quickly hit the 1 GB/day cap.

ChillaxSIM does not provide a South Korea eSIM that includes a phone number or SMS capability. Their South Korea offerings are limited to data‑only plans, so travelers cannot receive calls or text messages on an active phone number. For voice and messaging needs, users typically rely on VoIP applications such as WhatsApp, Telegram, and iMessage that work over the data connection.

ChillaxSIM offers 46 single‑country data plans and 5 multi‑country plans that include South Korea. The plans are available in both fixed data amount and daily data‑cap formats, allowing users to choose between a set data allotment for the validity period or a daily limit that renews each day. Prices on the site range from approximately $2.90 to $157.42, with data caps spanning from 1 GB up to 100 GB and validity periods of 1 to 30 days.
