Kolet eSIM Data Plans for South Korea

Kolet does not provide a truly unlimited high‑speed data eSIM for South Korea. The plans that carry the “UNLIMITED” name give 5GB of 5G data per day for the chosen validity period, after which the speed drops to 1024 kbps. These are fixed data plans, not unrestricted data bundles. Travelers who need more data can opt for larger fixed plans such as the 20GB for 30 days plan or the 10GB for 30 days plan, which deliver full‑speed data up to the stated cap without a reduced speed threshold. Choosing one of these fixed plans can offer better value for most users unless they anticipate usage beyond the available data quantities.

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.
