I have a Blackberry Curve. I have used the online call blocking feature twice now and it works! You can have up to 5 numbers blocked at any one time for free for 90 days. Or... wireless customers can add that feature for $1.99 per mo.
My only problem is that I can't seem to find the page I did all of that on. It's like they're trying to hide it, or something. I keep getting re-directed to this forum. Hmmm...Where is it Verizon? I need it again.
To anyone else just keep searchin', It's there someplace.
Log in to your account on verizonwireless.com; on the main overview page, there are 4 areas, and under Plan, the last box is "Block Calls and Messages" - that will take you to an area where you can set up the blocks.
