Halo eSIM eSIM Data Plans for South Korea

Halo eSIM does not provide a truly unlimited high‑speed data plan for South Korea. The plans that carry “Unlimited” in their names give 3GB of high‑speed data each day, after which speed is reduced to 1 Mbps until the next day.
If you need a higher data allowance with no throttling, Halo eSIM offers fixed data plans such as 20 GB for 30 days or 10 GB for 30 days. These plans give you a set amount of high‑speed data that can be used at any time within the validity period, and they may be more cost‑effective unless you are an extremely heavy data user.

Halo eSIM does not provide a South Korea eSIM that includes a phone number or SMS capability. Only data‑only plans are offered for South Korea.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in South Korea before purchasing a plan.

Halo eSIM provides 38 plans for South Korea, with 12 single‑country options and 26 multi‑country packages. Among these, some plans have a fixed data amount while others set a daily data cap. Prices range from roughly $1.99 to $141.76, the data caps span 1 GB to 20 GB, and validity periods extend from 3 to 30 days.
