simpleSIM does not provide a true unlimited data eSIM for Singapore. All plans that carry the word “Unlimited” actually have a hard data cap—usually 1 GB per day or a fixed total amount—and once the cap is reached, the network speed is throttled to a reduced rate (for example 384 kbps or 128 kbps). Therefore the “Unlimited” label refers only to the absence of a billing cap, not to the availability of unrestricted high‑speed data.
For travelers who want a larger data allowance, simpleSIM offers fixed‑data plans instead. A notable example is the 50 GB plan, valid for 90 days, and the 20 GB plan, valid for 30 days. These bundles allow users to download at full speed until the allocated data is used up. In most cases, choosing a fixed data plan can be more cost‑effective unless a user anticipates very heavy data consumption.
