Astaroam eSIM Data Plans for South Korea

Astaroam does not provide a truly unlimited data eSIM for South Korea. All of its plans have a fixed data allowance, and after the specified amount is used the speed is reduced to 1000 kbps. Travelers who need a large amount of high‑speed data can choose from Astaroam’s fixed data plans, such as the 50 GB plan valid for 90 days or the 20 GB plan valid for 30 days, which offer substantial data without the speed throttling that applies to the “Unlimited”‑named plans.

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.
