My device is ringing or vibrating more times than expected
For calls, the number of times that your BlackBerry® device vibrates is not determined by the number of vibrations that you set in your sound profile, and there is no setting for the number of rings if you do not subscribe to voice mail. Your device vibrates or rings until the caller or the wireless network ends the connection.
