Astaroam eSIM Data Plans for South Korea

Astaroam does not provide a truly unlimited data eSIM for South Korea. All plans that carry an “Unlimited” label give 3 GB of high‑speed data each day; once that daily limit is reached the speed is reduced to 1 000 kbps.
If a larger, fixed‑data plan is preferable, Astaroam offers alternatives such as a 20 GB plan valid for 30 days at $10.56 (covering South Korea and 17 additional countries) and a 50 GB plan valid for 90 days at $33.17 for the same coverage area. These plans include tethering and may be more cost‑effective for users who need a substantial amount of data.

Astaroam does not provide eSIM plans for South Korea that include a phone number or SMS capability. Only data‑only eSIMs are offered by the provider. Travelers who need voice and messaging can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but should verify that those services are accessible in South Korea before purchasing.

Astaroam offers a range of plans that cover South Korea, with 13 single‑country options and 26 multi‑country options available. The catalog includes daily data‑cap plans—where the data allowance resets each day—and fixed data‑cap plans that provide a set amount for the whole validity period. Across all plans the price ranges from about $2.04 to $48.51, while the data caps vary between 500 MB and 50 GB, giving travelers a broad spectrum of choices to suit short trips or extended stays.
