4. Do not use public wi-fi
Using public Wi-fi networks can be dangerous mainly because it is easier for hackers to obtain your data. And so, what can you do?
Well, for starters, remember to create strong passwords, it will make their job harder to access your documents and then use a VPN, virtual private network, that way you can still connect your phone to the public network and keep your personal things safe.
If you do not have a VPN, do your best and turn off your internet until you get home or you can use your mobile data.
