NiftySIM does not provide a Singapore eSIM plan that includes a phone number or SMS capability. The plans that are available from NiftySIM for Singapore are data‑only.
Travelers who need voice or messaging can use the data connection to access VoIP applications such as WhatsApp, Telegram, and iMessage. They should verify that these services are accessible in Singapore before relying on them, as some destinations may block or restrict certain apps or VoIP services.
