Create a blacklist
There may be certain people who have your mobile number but
who you'd rather not take calls from. Whether they are ex-partners,
old clients or pesky call centres, we all have certain numbers we'd
like to block from our phones. Instead of having to manually stop
a call each time you're called, you can set up a blacklist of numbers
whose calls will automatically be rejected (Fig 3).
In the Phone app, tap the Menu button that is located at the
top of the screen and then select the Settings. Next, tap Cell>Call
rejection and make sure that the slider for Auto reject mode is
showing green. If it is grey then the function won't work, so simply
slide it to the right to ensure that you're able to block numbers.
Next, tap Auto reject list.
