While it’s generally a good idea to avoid using public Wi-Fi networks, sometimes they’re a necessary evil. If you do have to use one, disconnect them from any Wi-Fi connections when not in use. You never know who (or what) could be connected to a public Wi-Fi network, especially while you’re away from your device.
More than likely someone has asked for your Wi-Fi password when visiting your home. A more convenient and safer alternative than giving it away is to set up a guest Wi-Fi connection. Guest networks can be left open, plus they separate their traffic from your main SSID, which can inhibit the spread of malware.
Many mobile devices will automatically seek and connect to available wireless networks. Also, Bluetooth enables your device to connect wirelessly with other devices, such as headphones or automobile infotainment systems. Deactivate these features so that you only join to wireless and Bluetooth networks when you want to connect.
With automatic Wi-Fi connectivity enabled, your mobile device will connect to any known network or SSID that doesn’t require a password. You might be at risk if these Wi-Fi connections are monitored by untrusted third-parties. Set your your mobile devices to forget networks you no longer need, or just turn off Wi-Fi entirely.
Use your mobile network connection. Your own mobile network connection, also known as your wireless hotspot, is generally more secure than using a public wireless network. Use this feature if you have it included in your mobile plan.
