airdatalink eSIM Data Plans for Singapore

There are no unlimited data eSIM plans from airdatalink for Singapore. All available plans list a specific data cap, such as 20GB or 50GB for 30 days, or 20GB for 30 days with a different price point.

Travelers who need more data can select a fixed‑data eSIM from the catalog, such as the Singapore eSIM with 20GB for 30 days or the Southeast Asia 5 eSIM with 50GB for 30 days. Choosing a fixed data amount can be more cost‑effective for heavy data users, while airdatalink does not currently provide a truly unlimited option for Singapore.

airdatalink does not provide an eSIM plan for Singapore that includes a phone number or SMS capability. The provider offers only data‑only eSIM options for travelers visiting Singapore.

Because the plan lacks a traditional mobile number, calls and text messages can still be made through on‑demand VoIP services such as WhatsApp, Telegram and iMessage, which work over the data connection. If a conventional phone number or SMS service is required, you may need to consider a different provider.

AirDataLink offers five single‑country eSIM plans and 54 multi‑country plans that are valid in Singapore. The available plans span a price range of about $2.89 to $69.39 and a data cap range of 1 GB to 50 GB. Among these, 42 plans are capped on a daily basis while 17 provide a fixed data allowance for the entire validity period. Some plans include additional features such as tethering or reduced speeds at 384 Kbps or 128 Kbps.
