ESIMFUN eSIM Data Plans for Singapore

ESIMFUN does not provide a truly unlimited data eSIM for Singapore. All of its plans carry a fixed 100 GB cap, and the plans are marketed with “Unlimited” in the name only to indicate that the data rate is not reduced after the cap is reached. Travelers can choose from the available fixed‑data options; for instance, a 5‑day plan delivers 100 GB for $15.48 USD, while a 30‑day plan offers the same 100 GB for $45.87 USD.

ESIMFUN does not provide Singapore eSIM plans that include a local phone number or SMS capability. The provider’s Singapore offerings are limited to data‑only eSIMs, so travelers cannot receive or send traditional SMS messages or make call via a Singapore mobile network. However, popular VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection for voice calls and text messaging.

ESIMFUN lists 53 multi‑country data plans that are applicable when you travel to or from Singapore; there are no single‑country plans for that country.
The available plans vary in price from about $8.20 to $208.89, with data caps ranging from 1 GB up to 100 GB and validity periods from 3 days to 30 days. Among these, 38 plans offer a fixed data amount, while 15 have a daily data cap.
