Astaroam eSIM Data Plans for Singapore

Astaroam does not provide an unlimited‑data eSIM for Singapore. Travelers who need high‑volume data can instead choose from Astaroam’s fixed data plans. For example, the Singapore 20GB 30Days plan costs $16.81 USD and offers 5G connectivity, while the Singapore 10GB 30Days plan is $11.68 USD and also includes 5G. These options give you a set amount of data for a month, and for most users they are more cost‑effective than a hypothetical unlimited plan, unless you are an extremely heavy data consumer.

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 6 single‑country plans and 18 multi‑country plans that include Singapore. All of the plans provide a fixed data allowance, ranging from 1 GB to 20 GB, with prices spanning from $2.68 to $52.14 and validity periods of 7 to 30 days. Some plans also allow tethering.
