Wi-Fi technology

Depending on your BlackBerry® device model, the Wi-Fi® feature might not be supported.
About connecting to a Wi-Fi network
With Wi-Fi® technology, your BlackBerry® device can access the Internet by connecting to a wireless router or wireless access point at your
home, work, or in a hotspot area. Your device uses the Wi-Fi network instead of the mobile network to visit web pages, send and receive email
messages, and so on. When you connect to the Internet with a Wi-Fi network, you might avoid data charges that are associated with using your
mobile network, and, in many cases, the connection speed is faster.
