Numerous mobile devices help in connecting with different kinds of networks, which also include Wi-Fi networks. You can be extremely tempted to check the balance or even make transfers when you are grabbing a drink in any coffee shop. However, before you are logging into the account, it is a must that you check whether you are connected to any public network.
Public connections are not secure at all. Most places, which offer public Wi-Fi, are responsible for warning users to avoid sharing sensitive information. If you have to check your account information, you must switch to other networks. In case you are using your smartphone, you need to disable your Wi-Fi and switch to the cellular network. You need to be extremely careful because you never know who is going to steal your information.
