MobileSIM eSIM Data Plans for Singapore

MobileSIM does not provide a true unlimited data eSIM for Singapore. The plans that carry “Unlimited” in their name give a high‑speed allowance of 3GB per day and, once that daily limit is reached, the speed is throttled to 1000kbps. Therefore, the data is not unrestricted while the connection remains at full speed.

Instead, MobileSIM offers fixed‑data plans that can be more cost efficient if you need a large amount of data without the risk of a speed cut‑off. For example, a 20GB plan for 30 days costs $23.00 USD, and a 100GB plan for 180 days costs $89.00 USD. These plans give you a specified data cap without the reduced‑speed caveat that applies to the “Unlimited” offerings.

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 currently has 12 single‑country data plans for Singapore and 22 multi‑country data plans that include Singapore among their destinations. The single‑country options range in price from about $2.34 to $89 and offer data caps spanning 200 MB to 100 GB; these are fixed‑amount plans, meaning the customer receives a set quantity of data for the whole validity period. The multi‑country plans align with the same price range, but they use daily data caps, allowing the customer to consume a specified amount of data each day rather than a single total amount. This structure provides travelers with flexibility in choosing a plan that best matches their stay length and data requirements.
