esimzon eSIM Data Plans for South Korea

esimzon does not provide a truly unlimited high‑speed data eSIM for South Korea. The plans that carry the word “Unlimited” actually offer 25GB of high‑speed data per day and, after that amount is reached, the speed is reduced to 8000kbps. For travelers who want a larger, unthrottled data allowance, esimzon offers fixed‑data options such as a 30GB 30‑day plan for $20.99 USD and a 50GB 30‑day plan for $35.99 USD, both with 5G coverage across South Korea.

Esimzon does not offer an eSIM for South Korea that includes a local phone number or SMS functionality. The available plans are data‑only, allowing internet access but not providing inbound or outbound calls or text messages. Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for communication instead.

For South Korea, esimzon offers six single‑country data plans and seventeen multi‑country data plans. The single‑country offerings are all daily data‑cap plans, which mean the data allowance is refreshed each day, while the multi‑country plans are fixed‑data‑cap plans that provide a set amount of data for the entire validity period. Across all plans, prices range from about $2.55 to $110, and data capacities vary from 1 GB up to 50 GB. These ranges give travelers a broad spectrum of options depending on their usage needs.
