Phone Etiquette
Sometimes an e-mail or letter just isn't quick enough or personal enough to handle a situation. Sometimes you have to make a call. Certain elements of phone conversation are as formulaic as written communication: greetings, asking who is calling, asking what the call is regarding, and asking about leaving a message, for example. Take a minute to think about how you phrase these things in English, and then take a look at how it's done in Spanish.
Mobil or cell phones are extremely common in Latin America and Spain. Service is reliable and often comparatively inexpensive. The most common terms for mobile phones are el celular and el móvil. If you need a new battery, ask for una pila or una batería.
Business phone etiquette usually stipulates that phones are answered with the name of the company, the identity of the speaker, and a general greeting ranging from “good morning” or something similar to any number of formulaic phone greetings. When you answer your phone at home, however, you probably only say “hello.” Phone greetings vary from country to country, and include expressions like
