AeroSims eSIM Data Plans for South Korea

AeroSims does not provide a true unlimited data eSIM for South Korea.
The plans labeled “South Korea Unlimited” give 5GB of high‑speed data each day; after the quota is used the speed is throttled to 384kbps. All other options are fixed data plans, such as the Seoul 50GB/30 days or Seoul 20GB/30 days bundles, which deliver a set amount of high‑speed data that must be used within the specified validity period. These fixed plans can be more cost‑effective for most travelers, while the “Unlimited” title only refers to the daily allowance before speed reduction.

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 offers 12 single‑country data plans that cover South Korea and 27 multi‑country plans that include South Korea as part of a broader regional package. The available plans span a price range from $3.90 to $167.15 and a data cap range from 3 GB to 50 GB. Some plans provide a fixed data amount for the entire validity period, while others impose a daily data cap, allowing users to manage usage on a day‑by‑day basis.
