Comet SIM eSIM Data Plans for Singapore

Comet SIM does not provide an unlimited data eSIM for Singapore. The available Singapore‑only plans are fixed data plans that must be used within a set validity period. For example, the Singapore eSIM — 20GB / 30 days plan gives 20GB of data for 30 days and costs $19.90 USD, while the Singapore eSIM — 10GB / 30 days plan offers 10GB for 30 days at $12.90 USD. A similar 20GB / 30 days plan is also available for Singapore, Malaysia and Thailand, and for a broader Asia or global coverage, but all of these are fixed data plans with a 30‑day validity. Choosing a fixed data plan can be more cost‑effective unless a traveler expects to use data beyond the plan’s allowance.

Comet SIM does not provide a Singapore eSIM that includes a phone number or SMS capability. The provider offers only data‑only eSIM plans for Singapore.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to these apps, so it is advisable to verify that the services you rely on are available in Singapore before purchasing a plan.

Comet SIM offers five single‑country data plans and fifteen multi‑country data plans for Singapore. The plans cover data caps from 1 GB to 20 GB with prices ranging from about $3.90 to $119.90, and validity periods span 7 to 30 days. All plans provide a fixed data amount rather than a daily data cap.
