I even tried pressing the dialer and pressing *228. No such luck.
The solution: call Verizon at 1-800-922-0204. I found the lady at the call center over-the-top helpful and she got my phone activated without problems.

She'll more than likely ask you to power it down and then back up--and I'm not really sure how you can do that while talking to her. So, bottom line, call from a land line or another cell phone.
