why does my nokia lumia 928 say extended network

I can not receive or make calls, it go straight to my voicemail when I have an incoming call

Are you on Verizon?

Try calling 611 and speaking with a Vzw rep.

Is it new service or a new phone on an existing service? Maybe it is just lag getting the phone on network...
