Cellesim eSIM Data Plans for South Korea

Cellesim does not provide an unlimited data eSIM for South Korea. The available plans are fixed data bundles, each with a specific cap and a 30‑day validity. For example, the 50GB 30d plan gives 50 GB of data for $59.50 USD, and the 20GB 30d plan offers 20 GB for $24.31 USD. If a traveler needs a large amount of data, choosing a fixed bundle can be more cost‑effective unless they are an extremely heavy data user.

Cellesim does not provide South Korea eSIMs that include a phone number or SMS capability. Only data‑only plans are available. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging, but some destinations may block or restrict certain apps, so it is wise to confirm that the services you rely on will work in South Korea before purchasing a plan.

Cellesim offers 17 single‑country data plans for South Korea and does not provide any multi‑country plans. The available plans range in price from about $3.59 to $144 and in data cap from 1 GB to 50 GB, with validity periods between 5 and 30 days. Ten of the plans feature a daily data cap, allowing a set amount of data each day, while seven plans offer a fixed data amount that is available for the entire validity period. Tethering is permitted on some plans, and a reduced speed of 512 kbps may apply in certain cases.
