AeroSims eSIM Data Plans for South Korea

AeroSims does not have a truly unlimited data eSIM for South Korea. The plans that carry the “Unlimited” label actually provide a fixed data allowance—5 GB per day on their 1‑ to 30‑day packages—after which the speed is throttled (the reduced speed is not listed in the available data). If a traveler needs more data, AeroSims offers fixed‑data alternatives. For example, a 50GB plan valid for 30 days costs about $34.90 USD, and a 20GB plan valid for the same period costs about $16.90 USD. These fixed plans can be more economical for most users, though very heavy data consumers might find the capped options restrictive.

AeroSims does not provide an eSIM with a local phone number or SMS capability for South Korea; all of its South Korea plans are data‑only. Travelers who need to make calls or send messages can use VoIP or messaging apps such as WhatsApp, Telegram, or iMessage over the data connection, but it is important to verify that these services are accessible in South Korea before purchasing, as some destinations may block or restrict certain apps.

AeroSims lists 12 single‑country data plans that are targeted for individual travellers in South Korea and 27 multi‑country plans that include South Korea among their regions of coverage. The single‑country offerings are all fixed‑data‑cap plans that provide a set amount of data for the duration of the plan, while the multi‑country options include both fixed data caps and daily‑cap variations to suit different usage patterns. Across the board the provider offers plans ranging from $3.90 to $167.15 with data limits between 3 GB and 50 GB, and validity periods from one day up to a full 180 days.
