Block calls

Note: If you have BlackBerry Mobile Voice System installed on your device or you have multiple phone lines, you might have to select a specific phone line first.
  1. In the Phone app, swipe down from the top of the screen.
  2. Tap Settings > Call Blocking.
  3. Set any of the switches to On.
The first time that you turn on call blocking, you will be prompted to create a password to lock your call blocking settings. To change your call blocking password, complete steps 1 and 2, and tap Change Password.
