how do you block a number
Depending on your phone, you may be able to block a number via the phone dialer app. Otherwise, you could block the number via My Verizon, i.e., Block Numbers | Verizon Wireless
What phone do you have? I have a S 7 edge and on there I tap the phone icon and on the right hand side you will see 3 dots. Tap that and go to settings then go to blocked numbers and add the number you want to block.
