SimSmash eSIM Data Plans for Singapore

SimSmash does not provide a plan with a truly unlimited high‑speed data cap for Singapore. All of its listed plans specify a finite allowance; for example, the plans called Singapore Daily Unlimited 10GB/day still provide only 10GB of fast data before throttling may apply.

If a user needs a large amount of data, SimSmash offers fixed data plans such as the Singapore 50GB for 30 days priced at $20.99 USD or the Singapore 20GB for 30 days at $9.99 USD. These options give a substantial high‑speed data allowance and can be more cost‑effective for many travelers.

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.
