TailSim does not provide a phone number or SMS service for its eSIM plans in Brazil. The provider’s offerings there are limited to data‑only connections, so travelers cannot send or receive traditional text messages or make standard voice calls with a local number.
With a data‑only plan, users can access internet‑based communication apps such as WhatsApp, Telegram, and iMessage. However, because some destinations may restrict access to these services, travelers should verify that the VoIP apps they rely on are available and functional in Brazil before purchasing a plan.
