SimSmash eSIM Data Plans for Singapore

SimSmash does not sell a true unlimited‑data eSIM for Singapore. All Singapore‑specific plans have a fixed data allowance—such as 20GB for 30 days or 50GB for 30 days—although the plan names include the word “Unlimited.” These names only indicate a nominal daily limit such as 0.49GB or 10GB; once the cap is reached the speed would normally be reduced, but the exact reduced speed is not listed in the available data. For travelers who need a large amount of data without a hard daily limit, a fixed‑data plan like the 20GB or 50GB options may be more cost‑effective.

SimSmash does not provide a Singapore eSIM that includes a phone number or SMS capability. The provider’s Singapore plans are data‑only, so travelers cannot receive or send regular phone calls or SMS messages on the device.

To communicate or make calls while in Singapore, users can rely on common VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection. However, availability of these services can vary; some destinations may block or restrict specific VoIP applications, so travelers should confirm that the apps they depend on are accessible in Singapore before purchasing a SimSmash plan.

SimSmash offers 12 single‑country plans and 18 multi‑country plans for Singapore. The plans available range in price from $0.89 to $94.99, with data caps between 490 MB and 50 GB, and validity periods from 1 to 180 days. Some of the options include tethering.
