Is US Cellular supported?


I am in an area that has very poor coverage for the main LTE contenders (AT&T, Verizon, T-Mobile and Sprint). My iPhone on AT&T gets no coverage whatsoever until I am a mile out of our community. I have heard from others that have no connectivity with other carriers.

The only carrier with decent coverage is US Cellular. Are they supported with Hologram (Especially the Nova)?
