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 sell an eSIM plan for Singapore that includes a phone number or SMS capability. The provider offers only data‑only eSIM options for travelers visiting Singapore.

If you need to make calls or send text messages, you can use VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection provided by the eSIM.

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.
