eSIM Cards eSIM Data Plans for South Korea

eSIM Cards does not offer a truly unlimited data eSIM for South Korea. The plans that reference “Unlimited” in their names actually provide a fixed amount of high‑speed data—1, 000 GB for the 5‑day and 10‑day options—with the potential for speed throttling after the cap is reached. Because these plans still impose a data limit, they are considered fixed‑data plans rather than unlimited.

Travelers who need large data allowances can choose from alternative fixed‑data options that eSIM Cards offers for South Korea. For example, a 100 GB plan is available for 5 days for $62.67 USD or 10 days for $69.48 USD, and a 20 GB plan is available for 30 days for $36.78 USD. These plans provide higher data limits and may be more cost‑effective than the capped “Unlimited” name plans unless a user is an extremely heavy data consumer.

eSIM Cards does not offer eSIM plans for South Korea that include a local phone number or SMS capability. The South Korea plans available from eSIM Cards are strictly data‑only, providing internet access for the validity period of the plan. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for voice and text communication.

eSIM Cards provides six single‑country data plans and two multi‑country plans for South Korea. Prices for these plans range from $8.17 to $69.48, while data caps span from 3 GB to 1, 000 GB. Validity periods are between 5 and 30 days. Some plans include a fixed data allowance, whereas others offer a daily data cap that resets each day. Tethering is allowed on applicable plans, although speeds may be throttled.
