To find free and open public mobile hotspots, you may use an app for a device, such as Wi-Fi Finder, which is available on the Google Play store and Apple App Store. Most mobile hotspots are not secure by their nature, so additional security measures are often necessary.
Mobile hotspots are public Wi-Fi networks that provide wireless connectivity to patrons at restaurants, malls, banks, hotels and in some cases the populations of entire cities. While mobile hotspots are a convenient way to stay connected to the Internet and save on data costs, they can also be dangerous if a device is not protected against hackers. The best mobile hotspots to use are those provided by phone and Internet service providers to subscribers, as these networks are password protected and afford a low level of security users.
A great way to protect a mobile device for use on a public Wi-Fi networks is by using a Virtual Private Network app, or VPN. VPNs bounce a device's connection around a private network of servers before routing the connection to its end point. This helps to make data, such as the IP address of the device, more anonymous, making it more difficult for attackers to gain access to private information.
