SimSmash eSIM Data Plans for South Korea

SimSmash does not provide a truly unlimited data eSIM for South Korea. All of its plans for the country have a defined data limit, and the plans that use the “Daily Unlimited” name actually cap the high‑speed data at 10GB per day. Once that amount is used, the speed is typically reduced, though the specifics are not listed in the available data.

Instead, SimSmash offers fixed‑data plans that may suit travelers who need more internet. For example, a 50GB plan is available for 30 days at $19.99 USD, and a 20GB plan is available for 30 days at $10.99 USD. These options can be more cost‑effective for users who consume a lot of data, as they avoid the speed throttling that comes after the capped daily limits.

SimSmash does not provide a South Korea eSIM that includes a phone number or SMS capability. The only eSIM plans available for South Korea from this provider are data‑only plans.

Travelers who need phone or text services can use the data connection to access VoIP applications such as WhatsApp, Telegram, and iMessage for voice calls and messaging over the internet.

SimSmash offers 12 single‑country data plans that cover South Korea and 18 multi‑country plans that include the country within their coverage list. The available plans range in price from $0.89 to $94.99 and provide data caps between 490 MB and 50 GB; some of the options allow tethering.
