Need to block calls from a spam caller?
To add a number to the blocked list
Select the gray circle "X" icon to the right of the number you wish to remove from the list.
Turning on Block anonymous calls will block all calls with no caller ID, marked private, or those with caller ID blocked. Calls from numbers that don't appear to be a real phone number will also be blocked with anonymous call blocking.
Turning on Block international calls will block all calls that are non US or Canadian phone numbers.
Note: Only full telephone numbers with area codes can be blocked. Partial phone numbers cannot be blocked.
