How to block numbers on a BlackBerry
We show you how to stop nuisance or unwanted calls on your BlackBerry…


Unwanted calls can be a real pain, whether it’s someone cold-calling about unclaimed PPI or a distant relative that insists on blabbering on at you for hours on end. If you want to put an end to such annoying, or even, harassing calls, here’s how to block calls and texts on BlackBerry phones.
BlackBerry has a nifty little feature that allows you to block phone calls and messages from anyone not in your contacts list. Annoyingly, however, it’s buried in the parental controls submenu, rather than being a dedicated option within BB10’s privacy settings.
How to block unknown numbers
1) Open security settings
Open the settings menu, and tap on the ‘Security and privacy’ tab.
2) Activate Parental Controls
Go into the ‘Parental controls’ tab, and use the slider to activate parental controls.
3) Set up password
If you’re activating parental controls for the first time, you’ll be asked to set up a password and optional recovery question.
4) Block unknown numbers
Once you’ve done that, you can tick the boxes to block calls or texts from numbers not already in your contacts.

How to block specific numbers
Unfortunately, BlackBerry doesn’t allow users to blacklist specific numbers from contacting them. If you want to block, for example, a particularly persistent ex, then you’ll have to do so via a third-party app.
There are plenty to choose from on the company’s BlackBerry World app store, so you can pretty much take your pick. There are various examples, including free and paid-for apps and almost all of them feature personal blacklists, along with other useful features.
