Choosing a connection
Your BlackBerry device is capable of a wide range of connections, to increase what you can do with your device and how it
interacts with other devices. Take a look at the list of connections to learn about the different types of connections, some
tips for when to use each connection, and maybe learn a few things you didn't know you could do.
Network connections
Mobile network
A mobile network connection allows your BlackBerry device to make calls and, if you have a data plan, use data
services such as Internet browsing. In some locations, such as in a hospital or on an airplane, you need to turn off
your mobile network connection, but usually you can just leave your mobile network connection on.

your mobile network connection, but usually you can just leave your mobile network connection on.
Wi-Fi
A Wi-Fi network connection is another way to get data services on your device, but unlike using the mobile network,
using Wi-Fi doesn't add charges to your data plan. Your device is designed to try to use saved Wi-Fi networks before
it tries to use the mobile network for basic data functions such as using the Internet or downloading apps. You can
leave Wi-Fi on so that as soon as you're in range of a saved Wi-Fi network, your device connects to it automatically,
but remember that if you leave Wi-Fi on all the time your battery can drain faster.
