So I went to three different stores in the last few days to ask about the Droid and if I could get a data-only plan. I go three different "No" answers:
Best Buy Mobile... said I had to get a voice plan, and that I'd have to pay $10/mo for navigation. Clearly didn't know what he was talking about.
Verizon Wireless Authorized Dealer... said the only data-only plans from Verizon were cards for laptops and such. The VZW website clearly lists a PDA/Smartphone data-only plan. Don't think he knew what he was talking about.
Official Verizon Wireless store... said VZW would require you to get a voice plan because VoIP + Google Voice would still use voice minutes in their systems. I don't think that's technically correct, VoIP is just data traffic. Unless VZW is secretly using VoIP for it's voice service already.
I think I'm going to order it. I figure the worst that can happen is Verizon won't activate the phone and I'll have to switch to the $70 plan I grudingly was going to get anyways.
