AeroSims eSIM Data Plans for South Korea

AeroSims does not provide a true unlimited‑data eSIM for South Korea. All of its “South Korea Unlimited” plans offer 5 GB of high‑speed data per day; after the 5 GB limit is reached the speed is throttled to 384 kbps. For travelers who need a larger unthrottled data allowance, AeroSims offers fixed data options such as the 50 GB for 30 days plan and the 20 GB for 30 days plan. These plans give a single, larger data bundle that can be topped up while still valid. Choosing a fixed data plan can be more cost‑effective unless a user expects to consume a very high volume of data.

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 provides 12 single‑country plans and 27 multi‑country plans that include South Korea. The available plans span a price range from $3.90 to $167.15 and offer data caps between 3 GB and 50 GB. Some plans feature a daily data cap, limiting the amount of data that can be used each day, while others use a fixed data cap that allows the full data allowance to be used over the entire validity period.
