I have:

AMERICA'S CHOICE II 450 ANY UNLIM N&W AND UNLIM IN CALLING $39.99

Do I have to change to a Nationwide plan in order to see the XV6900 as an upgrade on my company' b2b website?

I couldn't see it on mine either. I just called customer service and ordered the phone with my company discount and was done with it. I ended up getting the phone for 269.99 with no rebates necessary.

Do you still get the ADC and/or NE2 discount?
What data plan did you sign up for?

Isn't there a $23.99 "email and web for smartphone/pda" plan and a $35.99 "unlimited data" plan

(these prices are after 20% discount)

What phone number did you call?
Do you still get the mail-in rebate?

I just called customer service directly. Just dialed 611. No you do not get advanced device credit or mail in rebate. Yes you get the 20 percent feature discount which brings the unlimited data plan down. But I got mine for 269.99 no other discounts or rebates. If you order it online its 399.99 with a 50 dollar mail in rebate and 100.00 advance device credit if you sign up for the unlimited data plan. I preferred to not wait for the mail in rebate and just took the company discount.

Did you sign up for a data plan?

Yes I did just until they have the 29.99 plan out for it. But so far I'm enjoying the data

it sounds like the 6900 is a phone that verizon is making have a "nationwide" plan like they did with the voyager...i would say change your plan to the nationwide 450...and then upgrade

If I change the plan from America's Choice for $39.99 to Nationwide for $39.99, can I select the XV6900 as an upgrade?

No, he's wrong because I have and have had the nationwide plan and I still did not see it. Just make it easy on yourself and call Customer service and let them know of your company and they will process it just as easily for you
