MobileSIM eSIM Data Plans for Singapore

MobileSIM does not provide a true unlimited data eSIM plan for Singapore. The plans that carry “Unlimited” in their name offer a maximum of 3 GB per day; once that amount is reached the speed is reduced to 1000 kbps, so high‑speed data is not unlimited. Travelers who need consistently high‑speed data can instead choose one of MobileSIM’s fixed‑data plans, such as the Singapore 20 GB for 30 days plan priced at $23 USD, the Asia 50 GB for 90 days plan at $69 USD, or the Asia 100 GB for 180 days plan for $89 USD. These fixed‑data options can be more cost‑effective for users who expect to use a lot of data throughout their stay.

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.
