Because it is recommended to turn off WiFi when you leave the house and not worry about data consumption

Log into Internet, in mobile phones there are two types of connections. One is WiFi and the other is the telephone network (3G, 4G or 5G). Can both always be on or should one be off? Also, what is the battery drain represented by each? And there are differences regarding the safety.

Faced with this dilemma, many people walk away both connections activated permanently. The truth is that the remedy is worse than the disease, especially in these times when many operators offer a large margin of monthly data volume.

While fixed WiFi connections usually have unlimited megabytes of uploads and downloads, when using the 4G or 5G network you have to try to account for mobile data consumption so as not to pay off the entire tariff in a few hours of madness and downloads.

Although it seems that the only drawback of keeping the WiFi function active is battery consumption, the reality is that there is another much more important one: vulnerability. Also, nowadays smartphones don’t consume a lot of energy to search for networks.

These free networks usually used in airports, coffee shops, shopping malls, restaurants or hotels, provide free access to the Internet and just a couple of clicks to get online.

Another mistake is to think that these networks are more secure than connecting to a data antenna, along with thousands of other people’s devices that are around, but it’s not. The phone, when connected to the public router, is share information with other devices.

The data exchange with the antenna is minimal and it is very difficult for an attacker to know the name of the phone. These antennas have a better data encryptionTherefore, even when you are outside the country, it is the ideal option, instead of looking for a dubious landline connection.

The dangers of public networks

Also, many of these networks don’t require a login password, which means your device could connect to a network without your knowledge. This doesn’t have to be a problem, but it does increase your chances of being attacked or tracked by a cybercriminal.

Multiple network access points are saved by the mobile, further traces and information of the team are available to anyone. Also, when you move with the WiFi function activated, triangulation makes it easier for someone to detect your location.

The problem with connecting to wireless networks, especially in public spaces, is that it seems harmless, even though it’s a major security breach in using mobile devices.

Furthermore, if you keep this function active outside the home, the terminal will be constantly looking for wireless networks and this is not convenient, since the door is left open to possible attacks.

To avoid falling into a trap, all devices allow you to disable this tool and have customizable options, such as asking before connecting to a new or unknown network.

However, keep in mind that this will not be enough, since you also need to delete the wireless networks saved in the phone’s memory, no matter how secure they may be.
