There are public telephones - known locally as orelhões - scattered around the city, especially in busier locations. To use them, you will need to buy a phone card, with 20, 30, 40, 50 or 75 credits. All cards allow you to make local calls, long distance (interstate) and IDD (international) calls.
Before travelling, check whether your carrier offers roaming services in Brazil. If it does not, and you have an unlocked phone, you can buy pre-paid SIM cards, from one of the four carriers operating in Rio de Janeiro (Claro, Oi, TIM, Vivo). To call, after buying the SIM card, simply purchase a recharge card.
