1) Turn off Wi-Fi when not in use. Protect yourself and save battery power. Be sure to turn off the Auto Wi-Fi feature on your phone or tablet.

2) Don't trust unverified Wi-Fi connections that don't ask for a password. Most often, cybercriminals use such networks to steal personal data of users.

3) Do not go to online banks and other important services through open Wi-Fi networks in cafes or on the street. Use mobile internet.

4) Remember: banks, services and shops never send letters with a request to follow a link, change your password, enter a bank card number and a secret confirmation code or provide other personal data!
