ZenSim eSIM Data Plans for South Korea

ZenSim does not provide a truly unlimited high‑speed data eSIM for South Korea. The plans that carry the word “Unlimited” in their name, such as South Korea Unlimited STANDARD – 10 days and – 30 days, actually limit high‑speed data to 3 GB per day. Once that daily limit is reached, the download and upload speeds are throttled to a reduced speed that is specified in the plan details.

Travelers who need a predictable amount of high‑speed data can choose from ZenSim’s fixed‑data plans. The catalog includes a 20 GB plan for 10 days priced at $29.00 USD, the same 20 GB for 30 days for $30.00 USD, a 10 GB plan for 10 days at $18.00 USD, the 10 GB for 30 days at $20.00 USD, and a 5 GB plan for 10 days at $17.00 USD. These fixed‑data options offer a higher data allowance than the limited‑day “Unlimited” plans and are usually more cost‑effective for users who do not require a continuous, unrestricted data flow.

ZenSim does not provide a South Korea eSIM that includes a phone number or SMS capability. The only South Korea eSIMs offered by ZenSim are data‑only plans. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

ZenSim offers 8 single‑country data plans for South Korea. These plans cover a data range from 3 GB to 20 GB and are priced between $17.00 and $60.00, with validity periods that vary from 10 to 30 days. Within the selection, two plans feature a daily data cap model while the remaining six provide a fixed data amount, offering travelers flexibility depending on whether they prefer a set quantity of data or a daily allowance.
