During the peak of Carnival in Rio de Janeiro, especially at high-density events like the Sambadrome or popular blocos, local mobile networks experience significant strain due to the immense crowds. While HotelESIM connects to Brazil's top-tier networks such as Vivo and Claro, you may notice some reduction in data speeds. We recommend using your HotelESIM as a reliable backup for essential communications and navigation, while embracing the vibrant atmosphere. Even with congestion, it will still offer a more consistent connection than many public Wi-Fi options.
