Why not turn off your phone's Wi-Fi when you leave the house? These are the risks you're taking without realizing it.
When leaving home, we sometimes forget to turn off Wi-Fi on our mobile devices. We might forget or overlook it, assuming that mobile data is in use and Wi-Fi is off, but this isn't true. What happens is that when passing through an area with an open network, your phone will attempt to connect to it, with all the risks that entails.
What happens if I don't turn off WiFi when I leave home?
Leaving this feature enabled causes your mobile phone to constantly search for networks to connect to, leading to various problems. These include your smartphone automatically connecting to a public network and potentially being accessed from it, or connecting to fake or compromised networks created by cybercriminals, among others.
In this case, your personal and banking information could be stolen. Even if you are not connected to any service, your phone will continue to send information about your previous online activity. This information may be used to monitor your browsing activity, which could compromise your privacy and security.
All of this can be avoided by disabling Wi-Fi on our mobile phones or any device we use when we leave home. It's a simple gesture that can save us from many problems, such as having our phones or information monitored and losing complete control over them.
