Astaroam eSIM Data Plans for Macau

Astaroam does not provide a truly unlimited data eSIM for Macau. All of its plans for Macau have a fixed data allowance, ranging from 3 GB to 50 GB, and each plan has a set validity period. For travelers who need a large amount of high‑speed data, Astaroam offers fixed data plans such as the 50 GB plan valid for 90 days or the 20 GB plan valid for 30 days. These plans give a generous data allowance and can be more cost‑effective for most users compared to a plan that would throttle speed after a daily limit.

Astaroam does not offer a Macau eSIM that provides a phone number or SMS service. Travelers can only purchase data‑only plans from the provider. They can use commonly supported VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but access to these services may be limited or blocked in Macau, so it is advisable to confirm that the apps needed are usable before buying a plan.

Astaroam provides 6 single‑country plans and 14 multi‑country plans for Macau. The available plans range in price from about $2.73 to $34.05 USD and offer data caps between 500 MB and 50 GB. Plans are split into two main types: fixed‑data plans give a total amount of data for the entire validity, while daily‑cap plans allow a specific amount of data each day, which may help users control usage during longer stays.
