Hi I am an incoming student and will be studying in Minneapolis. I have a Lumia 730 DS which I had bought in India. It is a 3G handset, unlocked and country variant (CV). Will the phone work out of box with US carriers like AT&T, T Mobile, Verizon, Sprint, US Cellular for calling and internet ? Also I will be living at the U of M, so suggestions on carriers which have good coverage and 3G speeds at the U is appreciated. Thanks.
