When in Brazil, you can expect excellent 4G/5G coverage for your Truly Roaming eSIM in major urban centers like Rio de Janeiro, São Paulo, and Salvador. Even the primary Amazonian city of Manaus offers strong connectivity for your work needs. However, it is crucial to manage expectations for remote Amazonian areas. Once you venture deep into the rainforest on riverboats or to isolated lodges, network availability becomes sparse. While Truly Roaming leverages the best local networks, truly remote jungle environments will have limited to no signal, so plan your offline work accordingly.
