TraveleSIM.CH eSIM Data Plans for South Korea

TraveleSIM.CH does not provide an unlimited data eSIM plan for South Korea. All listed South Korean offers have a fixed data cap, with the largest plan granting 50 GB for 30 days and the smaller options providing 20 GB for 30 days. These fixed data plans are the only options available for travelers in South Korea.

Choosing a fixed data plan may be more cost‑effective for most users, while those with very high data consumption may need to carefully evaluate the data limits before purchasing.

TraveleSIM.CH does not provide eSIM plans for South Korea that include a local phone number or SMS functionality. Travelers who need a phone number or the ability to send SMS must seek another provider. The available plans from TraveleSIM.CH are data‑only eSIM plans that give internet access.

You can still use voice and messaging apps such as WhatsApp, Telegram, or iMessage over the data connection to communicate, although some destinations may block or restrict certain VoIP services. It is advisable to confirm that the apps you rely on are accessible in South Korea before purchasing a data‑only eSIM.

TraveleSIM.CH provides 13 single‑country plans that are limited to South Korea and 40 multi‑country plans that include South Korea in their coverage. The plans range in price from around $2.50 to $119, offer data caps between 1 GB and 50 GB, and are valid for periods between 7 and 365 days. The single‑country offerings give customers a fixed data amount for a set duration, while the multi‑country options bundle the same data amount across several countries, allowing travelers to use the data while moving between destinations.
