Choose the SPAM Control: There you can add up to 5 phone numbers that you do not want to contact you. This also prevents these #s from text messaging you.
*Press APPLY then you are done. They block these #s for 3 months at a time. So you will have to repeat the steps in 3 months.
*To Unblock these #s, do the same exact steps as above, except just delete the number you want to unblock. Press "APPLY" and the number is unblocked.
I did too, but I found this easier, and less taxing on my memory. You don't have to worry about yet another app running in the background and the call is blocked before it ever makes it to your phone. This means no missed call icons.
