TraveleSIM.CH eSIM Data Plans for South Korea

TraveleSIM.CH does not provide an unlimited data eSIM plan for South Korea. All its South‑Korea offerings have a fixed data cap, the largest of which is 50 GB for 30 days. Travelers who need more data can consider one of these fixed plans, such as the 50 GB, 30‑day bundle or a 20 GB, 30‑day option, which may be more cost‑effective unless the user is an extremely heavy data consumer.

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 data plans and 52 multi‑country data plans that include South Korea. The options range in price from about $2.35 to $112.07 and in data cap from 1 GB up to 50 GB. The single‑country plans are a fixed data amount for the entire validity period, while the multi‑country plans may offer a daily data cap that renews each day. This gives travelers a broad spectrum of choices in terms of cost, data volume and flexibility of use.
