ZenSim eSIM Data Plans for Singapore

No, ZenSim does not provide a truly unlimited data eSIM for Singapore. All plans called “Unlimited” actually allocate a fixed amount of high‑speed data, in this case 3 GB per day, after which the speed would be reduced (though the reduced speed is not specified in the available data).

Travelers who need larger data amounts can choose fixed‑data plans instead. For example, ZenSim offers a Singapore 20 GB plan for 10 days at $18.00 USD and a 10 GB plan for 10 days at $13.00 USD. These options give a larger overall allowance and may be more cost‑effective for most users.

ZenSim does not offer eSIM plans that include a local Singapore phone number or SMS capability. The provider offers only data‑only eSIMs for the region, and travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without needing a local phone number.

ZenSim offers 16 data plans for Singapore, comprising 8 single‑country plans and 8 multi‑country plans. The plans range in price from about $13.00 to $70.00 USD and provide between 3 GB and 20 GB of data valid for 10 to 30 days. Within these, 4 plans feature a daily data cap while the remaining 12 offer a fixed data amount. Some plans also allow tethering.
