Do you have any recommendations regarding mobile phones? Did you keep your home-country plan or use a local provider?
The least bad service is Claro/Net, but their customer service can be awful if you have to deal with a human being. The best customer service is Vivo (which I have), but I think the cell phone coverage and WiFi is a little lesser than what you get with Claro. Don't even think of the other providers (Oi, Tim). - Aug 2020
The consulate provides staff with cell phones. Otherwise, there are lots of plans and they are relatively cheap. - Jan 2011
