Do you have friends and contacts who aren't using a BlackBerry 10 device? If so, you can chat, call, send pictures, and
share videos with these contacts using joyn. If your wireless service provider supports joyn, within the Contacts app or the
Phone app, the
icon appears beside contacts who are using joyn, so that you can easily find other users.
joyn for BlackBerry 10 might not be available on your device, depending on your wireless service provider.
