You will see a short advertisement.

Train station, foreign city, signs in a language you can't read. Your country's SIM card has no roaming, the hostel address is in an email that won't load, and the map shows only a gray grid. Two blocks away, a public library has open Wi-Fi. Nobody told you.

Free Wi-Fi exists in stations, cafes, libraries, and hotels in any country, and also in your city, when your data plan runs out before the end of the month. All that's missing is the address and password. In this guide, you'll see the app that puts these networks on a map, how to connect in just a few taps, the apps that complete the kit for those who spend the day out or traveling, and the habits that make using public networks safe.

WiFi Map: the world's free networks on a single map.

WiFi Map functions as a shared map. Those who connect to a Wi-Fi network at a coffee shop, hotel, or station mark the location on the app and note the password provided by the establishment. According to the company, the map covers more than 200 countries. On Google Play, the app has over 100 million downloads and a 4.3 rating, with more than 3 million reviews. In the Brazilian App Store, the rating is 4.6.

• Networks around you: The map opens to your location and displays nearby hotspots. A filter prioritizes the closest or fastest network.
• Password and comments: When you tap on a spot, you see the password that the community left there and the message from those who passed by before.
• Path to the network: The app provides step-by-step directions to the location.
• Speed test: It measures the connection right after you log in.
• Bathroom and water: The same map marks public restrooms and drinking fountains, the kind of information that saves a trip to an unfamiliar city.
• Paid plan: The subscription removes ads and unlocks the ability to download regions for offline map browsing. The app also sells eSIM data packages for travel.

How to connect to a free network using WiFi Map

1. Install WiFi Map using the button at the top of this page, or from Google Play or the App Store.
2. On the first opening, allow location access. The app uses this information to map the networks around you.
3. Zoom in on your street or type the name of a neighborhood, station, or shopping mall into the search bar.
4. Turn on the filter and sort the results by distance or speed.
5. Choose a spot and check the network name, password, and messages from people who have been there. If someone has reported that the password has changed, you'll save yourself the walk.
6. Once there, access your phone's Wi-Fi menu, tap the name shown by the app, and enter the password.
7. Many websites display a welcome screen before allowing navigation, with an email field or an acceptance button. Complete it and you're done.
8. Run the app's speed test before starting a video call.

The map only exists because someone registered each point. If the password has changed, update it. If the network is new, add it.

Travel: have your map ready before leaving home.

The best time to hunt for Wi-Fi in another country is before you even board the plane, from the comfort of your couch, using your home internet.

• Search for the destination: Search for the city on the WiFi Map and see the networks near your hotel, the station, and the places you plan to visit.
• Save the passwords: Take a screenshot of the points of interest. If you subscribe to the app, download the entire region to use offline.
• Airport: Many airports have free Wi-Fi with quick registration, sometimes with a time limit. Use this time to download the city map and save the hotel address.
• Plan B: If your phone accepts eSIM, a travel data plan will cover the stretches without network coverage nearby.

Instabridge: Android connects automatically

On Android, Instabridge handles the tedious part: it automatically connects to working networks and skips over those that don't. The company claims to have amassed over 20 million passwords and access points. The app has a 4.1 rating on Google Play, more than 4 million reviews, and over 100 million downloads.

• Automatic connection: Good for airports and coffee shops, where the right chain isn't always the first one that comes to mind.
• Offline map: The list of networks is saved on the device and opens without internet access, useful when the SIM card is blocked for roaming.
• X-ray of each network: Speed, popularity, and data usage.

iPhone users will find another offering from the same company on the App Store: paid eSIM data packages.

Speedtest: test your network before the video call.

An open network isn't always a good network. Ookla's Speedtest measures download, upload, ping, and jitter with one tap, and has a video test that shows the maximum resolution the connection can handle. It has a 4.7 rating on Google Play, over 100 million downloads, and a 4.7 rating on the Brazilian App Store. A quick test saves meetings from freezing mid-sentence.

Proton VPN: a closed tunnel within an open network

On a public network, you share the same connection with dozens of strangers. A VPN creates an encrypted tunnel between your phone and the internet, and those on the same network can't see what's happening inside. Proton VPN has a 4.9 rating on Google Play, over 100 million downloads, and a 4.8 rating on the Brazilian App Store.

• Free plan with unlimited data: Connects with one touch, no registration required, to servers in 10 countries.
• Automatic cut-off: If the VPN goes down, the app blocks the internet so nothing goes unprotected.
• Paid plan: It offers servers in over 140 countries and an ad blocker.

Some countries restrict the use of VPNs. Check the rules of your destination before traveling.

Where to find free Wi-Fi in any country.

• Universities: If you study or work at an institution that participates in eduroam, the same login connects you to campuses in dozens of countries. Set it up before your trip.
• Public libraries and museums: They usually have an open network connection, a power outlet, and a chair to sit on.
• Long-distance trains and buses: Many airlines offer onboard Wi-Fi. Check when you buy your ticket.
• Large fast-food and coffee shop chains: Many offer free Wi-Fi to customers, sometimes with a quick registration on the first access.

Public network without surprises: seven habits

1. VPN enabled before any app. Turn it on first, open the rest later.
2. Beware of twin networks. If both “Aeroporto_Free” and “Aeroporto Free WiFi” appear, one of them may be a trap set by someone nearby. An employee will confirm which name is the real one in ten seconds.
3. Free Wi-Fi, no card required. If a website asks for your card number or email password to unlock the network, close it and look for another one.
4. Banking and shopping only with protection. Paying bills, opening your bank app, or changing your password: use a VPN or mobile data, never a raw, open network.
5. Two-step verification. Activate it in your email, social media, and bank accounts before traveling. Even with your password, no one can enter without the code.
6. Closed sharing. Keep your iPhone's AirDrop and Android's Quick Share visible only to your contacts.
7. Forget about the safety net on the way out. In the Wi-Fi settings, tap on the network and choose To forget. Otherwise, the device will automatically reconnect to any network that copies that name, in another neighborhood or another country.

Which app to choose?
