Voyasim does not offer an eSIM for Brazil that includes a phone number or SMS capability. Travelers can purchase only data‑only plans from this provider. Over the data connection, popular VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used to make calls and send messages, but some destinations may block or restrict specific apps or VoIP services, so users should verify that the applications they rely on are accessible in Brazil before buying a plan.
