ZenSim eSIM Data Plans for Singapore

ZenSim does not provide a truly unlimited data eSIM for Singapore. All Singapore‑based plans have a hard data cap, and plans that include “Unlimited” in the name actually offer 3GB per day with total data subject to a speed reduction to 1000 kbps once the daily allowance is reached.

Users who need a larger data allowance can choose from ZenSim’s fixed data plans. For example, the Singapore 40GB plan is valid for 30 days, and the Singapore 20GB plan is valid for 15 days, both offering tethering and no reduced speed during the included data cap. These fixed data plans can be a more cost‑effective option for most travelers unless an extremely heavy data user requires higher usage.

ZenSim does not provide a Singapore eSIM that includes a local phone number or SMS services.
Only data‑only eSIM plans are available from ZenSim for Singapore. Users can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging, but they should verify that these apps work in Singapore before purchasing a plan.

ZenSim provides 13 single‑country plans and 18 multi‑country plans for Singapore. The single‑country options include a mix of fixed‑data packages, such as 1 GB up to 20 GB, that are available for 5 to 30 days, while the multi‑country plans cover several destinations in the region and can range from 5 GB to 30 GB for 15 to 60 days. Across both categories, prices start around $5 USD and can go up to roughly $119 USD, and the data caps vary from 1 GB to 40 GB. Of the available plans, six are daily data cap multiples, allowing for a set amount of data each day, while the remaining 25 are fixed data cap plans that provide a single lump sum of data for the entire validity period.
