Astaroam eSIM Data Plans for Singapore

Astaroam does not provide a true unlimited data eSIM for Singapore. All plans that carry the name “Unlimited” actually grant 3GB of high‑speed data each day; once that daily amount is used, the connection speed drops to 1000kbps. If a traveler needs more continuous high‑speed data, Astaroam offers fixed‑data options instead. For example, a 20GB plan for 30 days runs for $8.93 USD, and a larger 50GB plan lasting 90 days is priced at $33.59 USD. These fixed‑data plans can be more economical for users who consume a lot of data, whereas the “Unlimited” designations are not truly unlimited.

Astaroam does not offer Singapore eSIM plans that include a phone number or SMS service. Only data‑only eSIMs are available from this provider for travelers in Singapore. You can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice calls and messaging, but some destinations may block or restrict these services, so travelers should verify that the apps they rely on are accessible in Singapore before purchasing.

Astaroam provides 15 single‑coverage plans and 32 multi‑coverage plans for Singapore.
The plans span a price range of $2.01 to $48.74 and offer data caps from 500 MB up to 50 GB.
Single‑coverage plans give a set amount of data for Singapore only, while multi‑coverage plans bundle data that can be used across several countries.
Astaroam also sells two types of plans: fixed data‑cap plans, which deliver a predetermined amount of data for the whole validity period, and daily data‑cap plans, in which the data allowance resets each day.
