Most accommodations – including hostels and midrange hotels – provide wi-fi access. It’s usually free, though some luxury hotels still charge exorbitant rates for it. You’ll also find free wi-fi in most cafes and in many restaurants, as well as in some shopping malls.
Given the widespread availability of wi-fi and the popularity of smartphones, internet cafes are a vanishing breed, though there are still a few scattered around Copacabana and other areas of the Zona Sul. The remaining places charge between R$6 and R$12 an hour.
Blame It on Rio 4 Travel offers internet access.
