Astaroam eSIM Data Plans for Taiwan

Astaroam does not provide a true unlimited data eSIM for Taiwan. All of its plans that use the word “Unlimited” have a data cap of 3 GB per day and a reduced speed of 1000 kbps after that limit is reached. For travelers who need larger data allowances, fixed data plans are available, such as a 50 GB plan valid for 90 days, or 20 GB and 10 GB plans both valid for 30 days. These fixed plans can be more cost‑effective unless the user is an extremely heavy data consumer.

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.
