A note on speaking Portuguese
These guides use Brazilian Portuguese. Você is a common everyday address; senhor or senhora may fit a more formal interaction. Eu gostaria and poderia can soften requests without making them complicated.
Keep the accents and nasal spellings, such as não and conexão. Portuguese in Portugal may use different everyday vocabulary or pronouns. The examples aim for broadly understandable Brazilian wording.
