Yesim eSIM Data Plans for Singapore

Yesim offers several unlimited data eSIM plans for use in Singapore. The plans start at $4.06 USD for a 1‑day validity and range up to $66.08 USD for a 30‑day validity, with additional “Unlim Day Pass” options that extend the period to 40 or 80 days for higher prices. All these plans provide access to 5G networks and allow tethering.

The unlimited designation is accompanied by a Fair Usage Policy: after heavy use, speeds may be reduced or throttled, although normal speed is maintained until that point. If you are concerned about potential speed restrictions, you can contact Yesim directly to confirm what the FUP thresholds are and how much data remains available at normal speed.

Yesim does not offer any Singapore eSIM plan that includes a local phone number or SMS capability. Only data‑only eSIMs are available from this provider. Travelers who need voice or messaging services can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in Singapore before purchasing, as some destinations may block or restrict certain VoIP services.

Yesim does not have a separate count for Singapore alone, but the overall catalog lists 9 single‑country plans and 35 multi‑country plans that include Singapore coverage. The plans range in price from about $0.53 to $234.66, with data caps spanning from 500 MB to unlimited, and validity periods from 1 to 365 days. Some plans allow tethering, may be limited to new users, and speed could be throttled under certain conditions.
