The first third party retailer to sell the phone in the US is Expansys
We don’t like to break your bubble, but the truth is that the Nokia Lumia 930 is basically just an international version of the Lumia Icon which is exclusively available at Verizon. And this is the reason why the US citizens are probably not going to be able to purchase the Lumia 930 as Nokia seemingly has no plans to officially sell it in the country. These intentions have been made clear a few days back when Nokia announced the availability details for the phone. However, you don’t have to worry much if you were planning to buy the Lumia 930 in the US because the third party retailers are definitely going to cater to your needs.
And the good news is that there is already one retailer called the Expansys which is offering the Lumia 930 through its US wing. They are selling the phone for $699.99 without a contract. At this moment, you can only get the black and green versions of the phone as the white and orange colors will arrive later on.
But the buyers should be careful since Nokia isn’t providing these phone officially in the US market and anyone buying the phone would first have to confirm whether the phone's supported network bands match up with their carrier’s or not. This should be checked for both the 3G as well as 4G LTE connectivity.
