Astaroam eSIM Data Plans for Taiwan

Astaroam does not provide a truly unlimited data eSIM for Taiwan. The plans that carry the name “Unlimited” give a fixed 3 GB per day allowance; once that quota is reached the speed drops to 1000 kbps, so the data is capped.
Alternatives include fixed‑data options such as the 20 GB plan valid for 30 days or the 50 GB plan valid for 90 days, which may be more cost‑effective for travelers who need a large amount of high‑speed data.

Astaroam does not offer a Taiwan eSIM that includes a local phone number or SMS capability. Travelers can only purchase a data‑only eSIM from Astaroam for use in Taiwan.

The data‑only plan allows patients to connect to Wi‑Fi or use cellular data on 5G, 4G and 3G networks. While the plan lacks a native telephone number, popular VoIP applications such as WhatsApp, Telegram and iMessage can generally be used over the data connection for calls and messaging. Some destinations block or restrict specific apps or VoIP services, so travelers should verify that the apps they rely on are available in Taiwan before buying an eSIM from Astaroam.

Astaroam provides 12 single‑country data plans for Taiwan and 14 multi‑country plans that include Taiwan coverage. The available plans feature both daily data cap options and fixed data amount options. Prices span from roughly $2.73 to $35.14, while data caps range between 500 MB and 50 GB across the range of offerings.
