Simbye eSIM Data Plans for Singapore

Simbye does not offer a truly unlimited high‑speed data eSIM for Singapore. The plans titled “Singapore Unlimited” provide only 2GB per day and throttle speed to 1000kbps once the limit is reached, so the data is not unlimited in the sense of continuous high‑speed use. For travelers who need more data, Simbye sells fixed‑data plans such as the 50GB plan valid for 30 days, priced at $44.99 USD, and the 20GB plan also valid for 30 days, priced at $19.99 USD. These fixed plans avoid speed throttling; however, they might be less cost‑effective for very heavy data users compared with a plan that offers unlimited data.

Simbye does not offer any Singapore eSIM plans that include a phone number or SMS capability. All of the plans available for Singapore are data‑only, providing internet connectivity without call or text services. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.

Simbye offers eight single‑country data plans that are specific to Singapore and eleven multi‑country plans that include Singapore. Most of the plans provide a fixed data amount – 17 of them have a set data cap – while a smaller subset, two plans, impose a daily data cap. Prices for these plans range from roughly $3 to $60, data caps cover a spectrum from 1 GB up to 50 GB, and validity periods vary between 7 and 180 days.
