The Call Manager module in BullGuard Mobile Security can be used to make sure unwanted or unsolicited calls or text messages don't get through to you. It can also be set to block all shortcode messages by default with the exception of the numbers you whitelist yourself.
The Blocked tab will list all calls and texts that were blocked throughout time and the reason for the block. The default Reason for blocked shortcode messages will be Blocked shortcode.
In order to manage restricted contacts, you need to use the Blacklist tab from the main Call Manager screen. Once there tap on Add to Blacklist and choose the Number, Contact or Entry from Call History you wish to block. Finally select what traffic should be blocked and enter a reason and tap on Block.
Use the Whitelist tab in order to unblock shortcode numbers from which you would like to continue receiving messages in case you activated the option to Block all shortcodes (for example your bank's or carrier's number).
In order to activate the Block all shortcode option, tap on the Cogwheel symbol while in the main BullGuard interface, choose Settings and tap on the slider next to the option.
