Kolet eSIM Data Plans for South Korea

Kolet does not provide a true unlimited data eSIM for South Korea. The plans listed under “South Korea UNLIMITED” give 5 GB of high‑speed data each day; once that limit is reached the speed drops to 1024 kbps, so the data allowance is still capped.

Instead, Kolet offers fixed data plans that can be suitable for travelers. For instance, the 20 GB for 30 days plan supplies 20 GB of data for one month, and the 10 GB for 30 days plan gives 10 GB for the same period. These fixed plans can be more cost‑effective unless a user expects usage beyond the prescribed data limits.

Kolet does not provide South Korea eSIM plans that include a phone number or SMS capability; all their plans for South Korea are data‑only. Travelers who need messaging or calls can use VoIP applications such as WhatsApp, Telegram, or iMessage over the Internet connection, although it is advisable to verify that these services are accessible in South Korea before purchasing a plan.

Kolet offers 13 single‑country data plans and 10 multi‑country data plans for use in South Korea. The available options cover data caps from 1 GB to 20 GB and prices ranging roughly from $3.99 to $121.80. Some of the plans provide a fixed data amount while others impose a daily data cap; 7 packages are daily‑cap based while 16 packages are fixed‑amount. Certain plans may also include a reduced speed of 1, 000 kb/s.
