eSIMzio eSIM Data Plans for South Korea

eSIMzio does not provide a truly unlimited high‑speed data eSIM for South Korea. Plans that have “Unlimited” in the name actually give 3 GB of high‑speed data per day and then reduce the speed to 1000 kbps thereafter.

Travelers who need more data can choose fixed‑data plans instead. For example, the Asia 100 GB plan is valid for 180 days, and the Asia 50 GB plan is available for 15 days, both offering high‑speed data up to the stated data allowance. These plans can be more cost‑effective for users who expect to consume large amounts of 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.
