Free Wi-Fi Near You: Where to Find It and How to Avoid Fake Networks
My data ran out in the middle of the street and my phone is just showing a white screen. The exit is usually just a few blocks away — but nobody puts up signs indicating where there's an open network, and the phone's network list doesn't say which ones are reliable.
There is a large network of free public Wi-Fi in Brazil, much of it maintained with public funds. In the city of São Paulo alone, there are... 7,842 active points According to the city hall, the network is available in squares, libraries, bus shelters, and health units. The problem is knowing where to look—and how to avoid connecting to the wrong network.

Why does free public internet exist?
It's not a courtesy: it's a digital inclusion policy. Municipalities are installing open access points in public spaces, the federal government is bringing satellite broadband to places where no operator has yet reached, and businesses are offering internet access hoping you'll stay longer.
Add it all up, and the free internet coverage area of an average city is much larger than it seems. The expectation that needs to be calibrated is speed: it works very well for messaging, maps, email, and browsing, but struggles with high-quality video.
