Block specific phone numbers from calling you on your Verizon Motorola Droid smartphone. There are quite a few directions you can go in order to accomplish not being bothered by a certain person calling you.
Option 1 – Send the call directly to voicemail.
Option 2 – Login to your Verizon Wireless account and enable Usage Controls ($5 a month per line).
Option 3 – Choose from a number of call blocker apps.
Personally, what I’ve done is installed CallBlock. You have to root your Droid though in order for this specific app to work.
