Horizon eSIM eSIM Data Plans for South Korea

No, Horizon eSIM does not provide an unlimited data eSIM for South Korea. All of its South Korea plans have a specified data cap, such as 10 GB for 7 days, 20 GB for 90 days, or 50 GB for 30 days. Travelers can choose one of these fixed‑data plans, which can be more cost‑effective unless very heavy data usage is expected.

Horizon eSIM does not provide a South Korea eSIM plan that includes a phone number or SMS capability. Only data‑only eSIM plans are available from this provider for South Korea.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict or block these services, so it is advisable to confirm that the apps you rely on are accessible in South Korea before purchasing an eSIM.

Horizon eSIM provides 11 single‑country plans and 13 multi‑country plans that include coverage in South Korea. These plans vary in price from about $0.31 to $309.16 and in data allowance from 100 MB up to 50 GB, with validity periods ranging from 7 to 365 days. Some of the plans also allow tethering.
