Absolutely not! This is a major advantage for adventure travelers heading to Brazil. Acquiring a local physical SIM card from carriers like TIM, Claro, or Vivo in Brazil famously requires a CPF (Cadastro de Pessoas Físicas), a local tax ID that tourists typically do not possess. With eSIMAdventures, you completely bypass this hurdle. Our eSIM operates as a roaming service, meaning no local registration or CPF is needed, allowing you to activate your plan and get connected instantly, ready for your Brazilian expedition.
