Astaroam eSIM Data Plans for Singapore

Astaroam does not provide a truly unlimited eSIM data plan for Singapore. The plans that carry the “Unlimited” label actually give 3 GB per day; after the daily allotment is used the speed is reduced to 1000 kbps. For travelers who need larger, unthrottled data packages, Astaroam offers fixed‑data options such as the 20 GB 30‑day plan for $8.92 USD or the 50 GB 90‑day plan for $33.54 USD, which cover the entire data volume at their full speed without daily limits.

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.
