4S eSIM eSIM Data Plans for Singapore

4S eSIM does not provide a truly unlimited data eSIM for Singapore. While several plans carry the word “Unlimited” in their names, the listed data cap shows a fixed amount—such as 3GB, 5GB, 10GB, up to 50GB—after which the speed is throttled to 1000 kbps. For travelers who need a large data allowance, the fixed‑data plans are the practical choice, for example the Singapore 50GB plan valid for 30 days or the Singapore 30GB plan valid for 15 days.

4S eSIM does not offer a Singapore eSIM with a phone number or SMS capability. The provider only sells data‑only plans for this destination, so travelers cannot receive or make standard voice or text calls on the local network. For voice and messaging, users may rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection; however, some destinations may block or restrict certain apps or services, so it is advisable to check that the applications you need will work in Singapore before purchasing a plan.

4S eSIM lists 57 single‑country data plans that cover Singapore alone and 108 multi‑country packages that include Singapore among their destinations. The coverage options range in price from about $1.47 to $146.84 and in data size from 714 MB up to 50 GB, with validity periods spanning 1 to 365 days. Among the offerings there are two main styles: fixed‑data packages that provide a set amount of data for the entire validity, and daily‑cap plans that allow a particular amount of data each day, resetting daily.
