Astaroam eSIM Data Plans for Singapore

Astaroam does not offer an unlimited data eSIM for Singapore.
Travelers can instead choose from fixed‑data plans, such as the Singapore 20GB 30Days (nonhkip) plan priced at $19.77 USD or the Singapore 10GB 30Days (nonhkip) plan at $12.76 USD. These plans provide 5G connectivity and allow tethering for the full 30 days of validity. Selecting a fixed‑data plan can be more cost‑effective for most users unless they require an extremely high data allowance.

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 lists six single‑country data plans and 18 multi‑country plans that include Singapore. The available packages span data caps from 1 GB to 20 GB and priced between $3.80 and $87.03. Single‑country plans provide a fixed amount of data for a set validity period, whereas multi‑country plans allow usage across several destinations while still respecting the data limit. Some of these plans permit tethering.
