About joyn
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.
For information about fees or conditions that might apply when using this application, contact your
wireless service provider.
