I recently moved and had my FIOS service transferred from my old apartment to my new condo. I kept my phone number when I moved.
When I attempted to log into verizon.com/fiosvoice this morning it had me go through the initial setup wizard. The wizard ask me for a backup number in case the power is out. So I type in my cell phone number and hit proceed. I then get a page not found message. When I try to do it again later I get the same issue. I can't get pass this inital setup wizard.
