The second step may not be necessary.
Please note that this process for me required one call to Verizon to get them to get it set up in the system again. One other possibility is that if you have an old Verizon phone, you can activate it, then activate the XV6900 again using the Verizon Wireless website, makes it a little less painful. And following that, probably just again like jadesse says, do *228 and option 1 on the phone.
