Astaroam eSIM Data Plans for Singapore

Astaroam does not currently offer an unlimited data eSIM for Singapore. The provider’s plans are all fixed‑data packages, the largest of which is a 20GB allowance. For example, the Singapore 20GB 30Days (nonhkip) plan is priced at $17.09 USD and includes 5G coverage only within Singapore. Another option is the Singapore & Malaysia & Thailand 20GB 30Days plan, priced at $19.87 USD, which also offers 20GB of data but covers those three countries. If a traveler expects to use more data than a single 20GB package provides, selecting one of these fixed plans can be more economical than a truly unlimited offering.

Astaroam does not provide Singapore eSIM plans that include a local phone number or SMS capability. The available plans are data‑only, meaning you can access the internet but cannot receive or place voice calls or send text messages through a traditional phone number. Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging needs.

Astaroam offers six single‑country data plans and twenty‑four multi‑country plans for use in Singapore. The available plans span prices from about $2.67 to $52, feature data caps between 1 GB and 20 GB, and are valid for 7 to 30 days. Some plans allow tethering.
