MobileSIM eSIM Data Plans for Singapore

MobileSIM does not offer a truly unlimited data eSIM for Singapore. The plans with “Unlimited” in their names actually have a fixed allowance of 3 GB per day and a reduced speed of 1000 kbps once the daily limit is reached.

Travelers who need more data can consider fixed‑amount plans instead. For example, a Singapore 20 GB plan for 30 days costs $23 USD, while an Asia 100 GB plan for 180 days costs $89 USD. These fixed plans provide a clear data allowance and may be more cost effective for most users who are not extremely heavy data consumers.

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.
