MobileSIM eSIM Data Plans for Singapore

No, MobileSIM does not provide a truly unlimited data eSIM for Singapore. The plans labeled “Singapore Unlimited data for X days” offer a 3 GB/day allowance, after which the speed is throttled to 1000 kbps, so the high‑speed data is limited.

If a traveler needs more data without the speed reduction, MobileSIM sells fixed‑data plans instead. For example, the Singapore 20 GB for 30 days plan costs $23 USD, while the Asia 100 GB for 180 days plan costs $185 USD. These plans give a larger data allowance at a fixed price and may be more cost effective for most users.

MobileSIM does not provide an eSIM plan for Singapore that includes a local phone number or SMS capability. Only data‑only eSIM options are available through the provider.

Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice calls and messaging, which do not require a phone number or SMS functionality.

MobileSIM offers 12 single‑country data plans and 13 multi‑country plans for Singapore. The available options range in price from about $5 to $185 and cover data caps from 1 GB to 100 GB, with validity periods spanning 3 to 180 days. Among the plans, there are 6 that use a daily data cap, limiting usage to a fixed amount each day, and 19 that provide a fixed data cap, allowing the same total data amount to be consumed over the entire validity period. These options give travelers flexibility depending on whether they prefer short‑term daily limits or longer‑term data allotments.
