iRoamly does not offer a truly unlimited data eSIM for Singapore. All of the listed plans have a defined data cap of 500GB and, according to the provider’s own description, the high‑speed 10 Mbps service stops after 100GB and drops to 384 kbps. Consequently, the plans are considered fixed data plans rather than unlimited offerings.
Customers seeking large data allowances can choose from several fixed‑data options. For instance, a 500GB plan can be purchased for 7 days for $16 USD or for 30 days for $62.50 USD on the iRoamly network, which delivers 5G coverage in Singapore. Other durations such as 5 days, 10 days, or 15 days are also available and follow the same data‑cap and speed‑reduction rules. These fixed plans remain cost‑effective for most travelers unless a very heavy usage pattern is expected.
