eSIMzio eSIM Data Plans for South Korea

eSIMzio does not offer a true unlimited‑data eSIM for South Korea. All plans listed for that country have a hard data cap; the highest daily allowance is 3GB per day, and after that threshold the speed is reduced to 1000kbps. Fixed data plans are the only options available. For example, the South Korea Unlimited — 30 days plan gives 3GB/day for 30 days, while the Asia 100 GB — 180 days plan provides a larger total allowance of 100GB over 180 days. These fixed plans may be more cost‑effective unless a traveler requires truly unlimited high‑speed data.

eSIMzio does not provide South Korea eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIMs for South Korea. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in South Korea before purchasing a plan.

eSIMzio offers 12 single‑country plans and 41 multi‑country plans for South Korea. The single‑country plans are fixed‑data plans – each offers a set amount of data for the entire validity period – while the multi‑country plans include daily data cap options that reset each day. Across both sets, prices range from about $2.03 to $228.12, and data caps span from 200 MB up to 100 GB. These plans also allow tethering and feature a reduced speed option of 1000 kbps on certain tiers.
