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.
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.
